  MAJOR FEATURES & CHANGES
============================

Change 4280523 by Patrick.Boutot

	Add option in AjaCustomTimeStep to wait until the frame to be ready. Previously, the frame was there but not yet processed so it was possible that it was not ready by the time we wanted to read it. It won't work with interlaced because the 2 fields are processed at the same time. In interlaced, will get a 30fps behaviour when we actually want a 60fps.
	Fix bug that didn't set and reset bIsOwned properly when it was first initialized as not owned.

Change 4280526 by Patrick.Boutot

	Add accessor to get the leaf media source or output.

Change 4280624 by Patrick.Boutot

	Add timecode acessor to media samples

Change 4280626 by Patrick.Boutot

	Rework the timing for AJA Media Player. Previously, we took the timing of the frame. That was a bad idea because if 2 incomings video frames were coming a the same time, you would only show one. Making the buffering system useless.
	That affects the Custom Time Step since it was waiting for the interrupt signal and in some behavior we would like the frame to be ready to be used by UE. Same the timecode in the MediaSample because we may not used it to stamps the frame.

	This prevents a crash that can happen if a source is quickly cleared and reset before the next tick of Time Synchronization.

Change 4296294 by Jon.Nabozny

052594d470 Initial support for Blueprint Graph editor "Quick Jump" bookmarks.
Change summary:
- Moved the FBlueprintEditor::OpenGraphAndBringToFront() API up into the IBlueprintEditor interface.
- Modified FGraphEditorCommandsImpl to define new "Quick Jump" commands for graph editor contexts. Keyboard shortcuts are currently set up as follows (where 'slot_index' is '0' through '9' on the keyboard):
    - Quick Jump to Bookmark: SHIFT + <slot_index>
    - Set Quick Jump Bookmark: CTRL + <slot_index>
- Modified FBlueprintEditor::CreateDefaultCommands() to map Quick Jump commands to actions within the top-level Blueprint editor toolkit context.
- Added implementations to FBlueprintEditor for handling Quick Jump commands within the relevant editor contexts.
- Added UBlueprintEditorSettings::GraphEditorQuickJumps to save Quick Jump bookmark info to local user settings (.ini).

Known issues:
- Keyboard input focus will be lost whenever the user clicks on a tab well at the top of the Blueprint editor window. As a result, quick jump keyboard shortcuts won't work again until the user clicks somewhere inside the tab to reclaim the input focus. This is a general UI problem that's not tied to this feature specifically.
- Similarly, top-level editor command keyboard shortcuts (including Quick Jump) won't work immediately after opening a Blueprint asset in a new editor window. The keyboard input focus is not set until the user clicks somewhere inside the tab area. All editors have this issue (not just Blueprint editor windows).

Change 4075849 by Wyeth.Johnson

	Metadata on location and velocity modules, new DI

Change 4076028 by Frank.Fella

	Niagara - Fix an issue where the list of relevant scripts in the shared script view model could get out of sync when changing properties on an emitter such as interpolated spawning and gpu simulation.  This could result in an emitter recompiling forever if it started as GPU and was then switched to CPU and then a force compile was requested since it would include the GPU script when determing the compile status, but it would never compile it.

	#jira UE-59220

Change 4076925 by Frank.Fella

	Niagara - Adding and removing pins from an assignment node wasn't correctly invalidating the graph which I broke with my crash fix 4058428 since I thought the refresh call would do that.

	#jira UE-59249

Change 4076971 by Frank.Fella

	Niagara - Made few changes to stack issue handling while fixing an issue where the stack error wouldn't change when the compile error changed.
	+ Changed the unique identifier for stack issues to be automatically generated from a hash of the combined stack editor data key and the long description of the error.
	+ Changed the stack issue unique identifier from an FName to an FString to avoid poluting the name table with lots of generated hash strings.
	+ Encapsulated all of the stack issue data to validate the required inputs.

	#jira UE-59251

Change 4076974 by Frank.Fella

	Niagara - Minor change missed in last checkin.

Change 4076990 by Frank.Fella

	Niagara - Fix the assignment node so that it uses a "Begin Defaults" node instead of a regular input node when it's hooking up linked defaults.

	#jira UE-59224

	Changing pin order

Change 4077426 by Wyeth.Johnson

Change 4081107 by Shaun.Kime

	Fixing underlying GPU collision system after Rendering refactored to use the FSceneTexturesUniformParameters instead of individual textures. Note that GPU collision only works with the primary back buffer. We will need more work to support split-screen or PIP.

	#tests Collsion test GPU now is functional, but we still get a few nondeterministic strays in different directions keeping me from turning it on at the moment

	+ Don't allow the user to drop a module if the usage flags of the target script aren't supported.
	+ Allow dragging to different scripts event if they are in different graphs, or different emitters.
	+ Transfer rapid iteration paramters correctly when moving modules between scripts.

	Fixing uniform buffer alignment and padding to 16 bytes for all vector types; bumping vec2 and vec3 uniforms to vec4, and adding component mask to code chunk for accesses to uniform chunks according to their initial type
	OpenGL requires this since because adherence to the std140 memory layout is shaky at best when it comes to sub-16-byte vector types

Change 4092040 by Frank.Fella

	Niagara - Fix some issues with modify, transactions, and change ids which was causing assets to be dirty or modified on load, or were allowing internal operation to be undone.
	+ Move some transactions from public utility functions into private functions called by menu items in the UNiagaraNodeWithDynamicPins.
	+ Prevent a few modify calls in UNiagaraEmitter from marking the package dirty since they're sometimes called as a result of compiling and in the other cases earlier modifies would have already marked the package dirty.
	+ In the system view model, don't create transactions when adding an emitter if the system view model is in emitter asset mode since the user should be able to undo it.
	+ In the system toolkit when opening an emitter asset initialize, clean up, and propagate the rapid iteration parameters before copying the emitter to prevent the change ids from getting out of sync after the compile completes.
	+ In the system toolkit when trying to see if an emitter has changed using the change ids, use the last synced id from the copied emitter instead of the original emitter since duplicating the emitter can change the id, and there's not way to set it externally.

Change 4094712 by Damien.Pernuit

	Niagara - Houdini:

	Houdini Niagara Data Interface:
	- Removed the GetCSVFloatValueByString function as String aren't currently supported by Niagara.
	- Particles in the CSV file can now be updated over time (not just spawned)
	- Added GetParticlePositionAtTime, GetParticleValueAtTime, GetParticleVectorValueAtTime returning a linearly interpolated value for a given particle at a given time.
	- Added GetParticleIndexesAtTime for getting the previous/next row indexes and weight to access the values for a given particle at a given time and handle the interpolation of the values.
	- Added GetCSVVectorValue for accessing a Vector value at a given row/col.

	Houdini CSV Assets now looks for the following attributes in the CSV "Title" line:
	- pos for position.
	- id and # for particle ID.
	- alive and life for calculating a particles LifeTime.

Change 4094932 by Frank.Fella

	Niagara - Fix a few more issues where asset editors would open with their assets modified.
	+ Fix rapid iteration parameter preparation so that it doesn't modify the parameter store if it doesn't change after syncing with the graphs and propagating from dependencies.  This fixes the emitter editor allowing changes to be applied on open.
	+ Refactor the change notification for the script tool kit so that it uses the graph change and property change messages to determine if any changes have been made and can be applied.

Change 4094978 by Damien.Pernuit

	Niagara - Houdini:

	Houdini Niagara Data Interface:
	- Since we can now update particles over time, renamed/modified most of the functions to make a clear distinction between row indexes (row) and particle ids (N)
	- Replaced GetNumberOfPointsInCSV by GetNumberOfRowsInCSV and GetNumberOfParticlesInCSV
	- Renamed GetParticleIndexesAtTime to GetRowIndexesForParticleAtTime and GetLastParticleIndexAtTime to GetLastRowIndexAtTime
	- Fixed some DI Functions that were using floats for input parameter instead of using integers.

Change 4095428 by Damien.Pernuit

	Niagara - Houdini:

	Houdini Niagara Data Interface:
	Fixed incorrect behavior of the GetLastRowIndexAtTime and GetParticleIndexesToSpawnAtTime functions due to supporting particle update over time.

	Houdini CSV Asset:
	Fixed missing UPropery for SpawnTimes and LifeValues array.

Change 4096355 by Damien.Pernuit

	Houdini Niagara:

	Fixed performance warning for UHoudiniCSV::GetParticleLifeAtTime()

Change 4096419 by Damien.Pernuit

	Niagara - Houdini:

	Houdini Niagara Data Interface:
	Added GetParticleLifeAtTime for accessing a given particle's life at a given time value.
	Fixed GetParticleVectorValueAtTime not bound properly.

Change 4096466 by Damien.Pernuit

	Niagara - Houdini:
	- Added GetNumberOfColumnsInCSV to the Houdini Data Interface
	- Added descriptions to the functions exposed by the DI

Change 4096528 by Damien.Pernuit

	Niagara - Houdini:

	Houdini CSV Asset:
	- As the DI expects the values to be sorted by time, if it's not the case, the CSV importer will sort them on import.
	- As the DI spawning functions relies on the particle IDs starting at zero and increment, the CSV importer will fix the particles IDs on import if it's not the case.

Change 4096838 by Yannick.Lange

	Fix focus search box on add parameter menu

	#jira UE-59502

Change 4097205 by Bradut.Palas

	Fixes for metadata details in script toolkit (now the apply and compile buttons refresh and sort the metadata collection). The metadata functionality is fixed. Delete, add and modify work just as before, but the sorting isn't applied because refreshing the whole collection is skipped for internal changes.

Change 4097721 by Frank.Fella

	Niagara - Make the lifetime of stack entries well defined so that we can safely remove delegate bindings and clear out pointers.

Change 4097962 by Bradut.Palas

	Stack issues now update fix delegates on each refresh, even if the fix GUIDs don't change, to account for other possible changes in the graph. Had to introduce unique identifiers for fixes too, now the issue entry is using the same recycle mechanism for fixes that the base stack entry uses for issues.

Change 4098192 by Damien.Pernuit

	Niagara - Houdini:

	Houdini CSV Asset:
	When importing the CSV file, the importer creates a list of the row indexes updating each particle.
	This greatly improves performance when accessing data in large files with a lot of particles updating over time.

Change 4098406 by Damien.Pernuit

	Niagara - Houdini:

	Houdini Niagara Data Interface:
	Added helper functions for accessing Color and Velocity values in the CSV file.

	Houdini CSV Asset:
	The importer now looks for the Color (Cd, color), Alpha (A, Alpha) and velocity (V) attributes.

Change 4099945 by Frank.Fella

	Niagara - Fix op description tool tip and keyword searches in the graph add menu, fix and standardize tool tip handling for script objects in menus, and add support for keyword searches for user defined scripts to match the built in ops.

	#jira UE-59402

Change 4100451 by Shaun.Kime

	Fixing wyeth's torus error, which was caused by us not properly initializing defaults. We now initialize defaults in three waves in spawn scripts. Wave 1 are any straight up constants at the top of the spawn function. Wave 2 is inlined in spawn just before the function that needs them is called. Wave 3 is at the bottom of spawn in a section called HandleMissingDefaultValues.
	Also updated the error and warning messages to be much clearer text.

Change 4103522 by Damien.Pernuit

	Houdini - Niagara:
	Big renaming pass on the  Houdini CSV Assets  and Data Interface to follow naming conventions:
	Replaced the GetCSVXXX functions by GetXXXX (GetCSVPosition is now GetPosition)
	Always use "row" instead of "line", "Point" instead of "Particle", "PointID" instead of "N" or "ID" etc.

	Houdini Data Interface:
	- Added the GetVectorValueEx and GetPointVectorValueAtTimeEx functions that allow the user to decide how the vector conversion from houdini to unreal's coordinate system is handled.
	- Replaced the GetParticleLifeAtTime function by GetPointLife, that returns the life of a particle at spawn time.
	- Added the GetPointType function returning the type of a given point.

	Houdini CSV Asset:
	- Added the editable SourceTitleRow UProperty.
	Editing this will trigger a reimport of the source CSV file and might be used to fix/modify column titles in the file.
	- Added support for "type" attributes.
	- Removed the unused StringValues buffer and GetCSVStringValues() functions.
	- Added assetTags so the Houdini CSV asset thumbnails show more infos on the CSV data.
	- Added the "FindSourceCSV" asset action to browse to the source CSV file.

Change 3864729 by Frank.Fella

	Sequencer - Fixed a few places which were modifying sequencer data, but not calling the NotifySequencerDataChanged.

Change 3864737 by Frank.Fella

	Niagara - Fix the timeline in the niagara editor plus other fixes.
	+ Turned on looping in the timeline by default.
	+ Added simulation options to control playback in the editor, including turning off auto-play, disabling reset on change, and disabling resimulation when changing while paused.
	+ Added a buttons to the timeline for each renderer an emitter has which shows a renderer specific icon and will allow navigation directly to the renderer with future stack changes.
	+ Fixed issues in the emitter life cycle and spawn rate modules which were preventing delay and looping from working consistently. (includes auto-test)
	+ Added top level metadata for modules.
	+ Added the ability to add metadata to a module and it's inputs to allow it to be edited directly using timed sections in the timeline.  Currently configured for the emitter life cycle module.
	+ Changed the way the "MaxSimTime" on niagara component works so that it now represents the maximum frame time which should be used when seeking the component to the desired age.  This previously was the maximum amount of simulation time to run which would prevent simple effects from simulating quickly, and would also allow more complicated effects to hang the UI while seeking.
	+ Changed the behavior of niagara component when seeking to desired age so that it always uses the exact specified seek delta instead of trying to seek to the exact desired age.
	+ Fixed the component so that systems which are seeking to the desired age in the editor no longer draw in fast forward mode.
	+ Changed the default playback range for effects in the timeline from 1000 seconds to 10 seconds, and fixed the timeline so that the playback range is serialized into the asset which will persist the setting across loads.
	+ Fixed scrubbing in the timeline so that it doesn't immediately reset when scrubbing backwards.
	+ Added a button to the timeline track for enabling and disabling isolation mode for emitters.
	+ Added a checkbox to the timeline to enabled and disable emitters from the timeline.
	+ Fixed PinToNiagaraVariable so that it asserts if bNeedsValue is specified and it can't actually provide a value.
	+ Create a class called FNiagaraStackFunctionInputBinder which allows binding to an input of a function on a stack so that you can easily set and get the value of the input without having to worry about modifying the graph or rapid iteration parameter sets directly.

	#tests Existing auto-tests and 1 new test for life cycle changes.

Change 3867179 by Frank.Fella

	Niagara - Turn off GPU simulation for test assets for Shaun.

Change 3869201 by Simon.Tovey

	Bypassing JonLs issue

	#tests no longer crashes.

Change 3869897 by Frank.Fella

	Niagara - Fix crashes when using the skeletal mesh data interface.  NOTE: The change to the actual skeletal mesh data interface code doesn't seem needed, but without it, it crashes with the stomp allocator on.  We'll have to investigate further.

Change 3870487 by Frank.Fella

	Niagara - Always generate cached skin data immediately, and make sure we're not indexing triangles that don't exist.  This is a temporary fix to avoid a crash when changing the skeletal mesh source on an effect in the level from the details panel.

Change 3877378 by Frank.Fella

	Niagara - Update the burst and lifecycle modules with new metadata for incoming timeline changes.

Change 3877564 by Frank.Fella

	Sequencer - Fix a few more places which were modifying sequencer data without calling NotifyMovieSceneDataChanged.

Change 3877565 by Frank.Fella

	Niagara - Remove old unused burst code from some runtime classes.

Change 3877567 by Frank.Fella

	Niagara - Add support for keying bursts on the timeline which is configured using script metadata.

Change 3877699 by Frank.Fella

	Niagara - Fix a crash in the new timeline code for when you have bursts, but you have inputs on the emitter lifecycle bound, also set lower bound of view range of the timeline to be -.1 so that you can more easily interact with keys at 0.

Change 3877715 by Frank.Fella

	Sequencer - Update the change type when pasting keys from the clipboard from Unknown to TrackValueChanged to avoid unnecessary work.  From code review on last change.

Change 3879285 by Simon.Tovey

	A couple of fixes for using struct constants

	#tests Jon's case now compiles and works correctly.

Change 3879378 by Frank.Fella

	Niagara - Fix a few spots where recursive graph traversal was visiting nodes multiple times because of diamonds in the pin connections.  This reduces a terrible hang in UNiagaraScriptSource::InitializeNewRapidIterationParameters from 5 minutes to 5 seconds but there are futher issues to investigate becasue even 5 seconds it too long.

Change 3879858 by Shaun.Kime

	Moved the VM script compilation to the DDC in order to facilitate better team compilation behavior. Significant changes to the translator and overall compile workflow to make the data behave better for a future multi-threaded compilation path.
	In order to know when to compile, a key is generated that uses the compile id's of the graphs that influence the compilation of our node. In this way, if an end user goes and edits a function or module and checks in, the overall compile id will not match b/c that function is in the dependency list of a system downstream. The system will then know to recompile. However, everyone else on the team will generate the same key because the asset in question was checked in with its local compile id already changed.

	Additionally, we now employ change tracking on traversals from a node graph. These traversals walk through all the nodes leading to a given output node and see if they've been altered. If they have, a new compile id is generated. If not, the old compile id is used. This also means that if you edit a particle update section in the stack, the emitter section won't force the system to recompile.

	GPU scripts now have their own script slot rather than riding alongside particle spawn scripts. This allows us to address them independently in the translator and put them in the DDC as well. Once the text is generated, we then go back out to the DDC to generate the shader associated.

	Known issues:
	+ Emitters are sometimes marked dirty on open
	+ Nodes connected to event writes aren't part of the hashing
	+ DataInterface signature changes don't dirty the compiles
	+ Struct changes don't dirty the compiles
	+ On system loading, we go out to the DDC instead of using existing scripts, which is slower..

	#tests all auto-tests pass, additional tests run to validate proper behavior

Change 3879859 by Shaun.Kime

	Content update post DDC change

Change 3882822 by Shaun.Kime

	Rather than throw a check, I instead emit an error when we can't match up a data interface and instantiate a CDO version. Not perfect, but this will let you recompile.

	#tests allows me to open jonathan's file

Change 3883538 by Shaun.Kime

	Moving particle-level scripts to compile with the emitter named Emitter in their internal scripts. This simplifies the dependencies quite a bit, but causes some complexity on the wiring side (most of which we were already doing anyway).
	Getting rid of some allocations in translation (still more to go).
	Fixed some of the logic for emitters that had modules of the same name to now properly concatenate.

	Compile version bumped, so all scripts will be forced to recompile. Not saving this into the test files for now, as I expect this to happen a bit for the near term.

	#tests all auto-tests pass, creating a new emitter and system on PC works

Change 3883552 by Shaun.Kime

	Niagara - Runtime changes to support sequencer animation
	+ Reset the simulation when force solo is changed on the component.
	+ Invalidate the render data and clear the buffers when resetting to avoid previously rendered particles from drawing.
	+ Automatically sync the override parameters in the component when the source assets exposed parameters change and removed forced syncing from various places.

	Niagara - Fix some safety issues with parameter initialization on the niagara component.
	+ Kill the current system if we synchronize parameters to avoid issues with data interface lifetime.
	+ Always sync parameters when the asset is set to prevent missing data interfaces in the override list.
	+ Add an enum to control how data interface parameters are handled when calling CopyParametersTo.
	+ When the system instance is copying the asset parameters, have it copy data interfaces by reference so that it's not creating data interfaces copies which will be deleted at the next garbage collection.

	#Tests Auto-tests, also doesn't crash anymore when opeining Jonathan's disolve effect and then opening a level.

Change 3897953 by Frank.Fella

	Niagara - Remove some namespace restrictions from the code that generates the available parameters to read from in the stack UI since it was preventing the use of custom namespaces in modules and it was not clear what issue it was solving since we already prevent scripts from addressing parameters from lower level scripts.  Also move user parameters to their own menu section.

Change 3899069 by Shaun.Kime

	Parallel compilation

	Major changes:
	Rather than a custom streaming version that we know influences a rebuild, I'm moving away to a guid that you need to regenerate if you change the compiler in any meaningful way
	needed for multiple reasons,
	1) if two people are making changes to the compiler, having something other than a guid as the value makes the content of the ddc ambiguous
	2) when iterating I often need to make multiple changes to get to a working final result, bumping the version number each time that happens gets old fast

	We fully clone the input graph to do the compile in the background. While the translation step is not a huge amount of time, it keeps the main thread responsive.

	We currently have a big critsec around the crosscompiler to bytecode as it isn't threadsafe. Future changes will push this to the ShaderCompilerWorker.

	#tests all tests pass as well as stress tests around saving while compilng, long compile times, etc.

	- Improved error/warning logging during the parsing of the file

	Houdini Niagara Data Interface:

	New helper functions returning the min index, max index and number of particles to be spawned for a given time value.
	Uses an internal LastSpawnIndex to avoid spawning the same particles twice.
	- Modified GetLastParticleIndexAtTime():
	If the CSV file doesn't have time informations, returns false and set the LastIndex to the last particle
	If desiredTime is smaller than the first particle, LastIndex will be set to -1
	If desiredTime is higher than the last particle in the csv file, LastIndex will be set to the last particle's index

Change 3940709 by Simon.Tovey

	Temp hacks for the skeletal mesh painting issues.

Change 3940960 by Yannick.Lange

	Only build parameter menu once when graphchanged is called multiple times in a frame.
	Also use the existing metadata from graph to build the parameter menu, because the metadata already looped through all nodes and pins.

Change 3941019 by Yannick.Lange

	Meta data UI refresh next tick to avoid refreshing multiple times a tick.

Change 3941853 by Simon.Tovey

	Adding more dynamic parameters

Change 3941957 by Frank.Fella

	Property Editor - Fix issues with property row generator to support the niagara stack.
	+ Make the detail tree node name accessible through the interface, and fix the implementations for category group and property item.
	+ Add a temporary fix for passing instance customizations from the property row generator to the detail property row through the detail layout builder.  This should be unified in a nicer way, but this will work for the time being.

Change 3942174 by Frank.Fella

	Niagara - Stack UI Pass
	+ Advanced rows are not handled properly per item.
	+ Expanded and scroll state is now saved in editor data per asset.
	+ Added a "View Options" drop down for showing all advanced rows, and for showing/hiding outputs.
	+ Added an option to collapse all stack items from the emitter header context menu.
	+ Added support for "Edit Conditions" on module and dymaic inputs which will enable and disabled an input based on the value of another input.  This includes showing a checlbox inline for the edit condition toggle input.
	+ Added support for "Visible Conditions" on module and dynamic inputs which will hide and show inputs based on the value of another input.
	+ Removed the pencil icon for locally editable values in the stack.
	+ Fixed issues with invisible search results.  It's still possible for a search result to not highlight the text correctly, but the outline never disappears.
	+ Removed pinning for module inputs.
	+ Fixed the event handler properties so that they use the property row generator instead of an embedded details panel.
	+ Unified indent handling across all stack classes.
	+ Unified stack editor data across all stack classes.

Change 3957065 by Bradut.Palas

	enable/disable mechanism for renderers

	#tests none

Change 3957802 by Olaf.Piesche

Change 3995291 by Yannick.Lange

	Parameter menu tooltip fix

Change 3997804 by shaun.kime

	Lookup table is off for this. Keys are 0,0 and 1,1, so you'd expect normalized age as a sampler to just return the same value from lookup. If LUT is disabled, this is true. If LUT is enabled, it isn't, especially the farther one gets from 0.

Change 3998124 by Simon.Tovey

	Fixed Curve LUT generation

	#tests editor
	#jira UE-57604

	UE-55750 focus curve editor when "show" button is pressed
	UE-55791 user variable curves cannot be shown in the Curve tab
	These issues were related and touched the same area of code, so I fixed them together. UE-55791 is basically just getting curve data from the system exposed variables too.

	#tests none

Change 4001253 by Frank.Fella

	PropertyEditor - Fix issues with external root handling.
	+ Fix external nodes not being cleaned up correctly when custom node builders rebuild children.
	+ Fix expanded state being trampled when processing external nodes due to the expanded nodes list being emptied every time RestoreExpandedItems was called.
	+ Fix performance issues with refreshing during tick by moving all calls to RestoreExpandedItems to UpdateFilteredDetails, and then only calling UpdateFilteredDetails once per tick as needed instead of per root property node and per root external node.

Change 4003365 by Shaun.Kime

	If the physical material has gone away, make sure to set value values. Note that if this data interface is going to go on in parallel to the game thread, we'll need something more sophisticated.

	Interpolated spawn on GPU does not yet work but checkpointing work.
	+ Added AdditionalDefines to the VMCompileId, switched interpoalted spawn to use that
	+ Added rough interpolated spawn support to translator by refactoring away from specific calls and hard-coded update/spawn somewhat... could improve for events
	+ Revised shader variables away from Phase0/Phase1 terminology to the true Update/Spawn meaning. Leaving the phase numbers as an implementation detail within the usf.
	+ Added ToString to ParameterStores for debugging
	+ Changed GPU ExecIndex() logic to actually work similar to the VM

	+ Collect data interface reads and writes from parameter maps during compilation so they can be hooked up a runtime.
	+ Add new runtime parameter stores for systems and emitters at runtime which bind the exposed data interfaces into the execution contexts.
	+ Fix the editor code which updates the compiled data interfaces so that it updates the correct ones regardless of where they are defined.
	+ Fix an issue where failed compiles weren't being propgated to the UI correctly.

	Parameters refactor:
	- Find parameters and references in graph
	- Renaming parameters, includes renaming all pins in the graph
	- Removing parameters
	- Find metadata when finding parameters, so we are not looping through all nodes/pins twice
	- Parameters list supports multiple emitters in systems

Change 4042058 by Simon.Tovey

	Refactored GPU parameters.

	- Shader now uses the DI default object to create the correct parameters struct.
	All parameter and buffer management now being handled inside this parameter struct.
	This allows far more encapsulated code for each DI.
	Allows us to reamove the GPU buffers from and the Scene texture refs that were in the base DataInterface class.
	Simplifies the API and process of implementing DI's on the GPU considerably.

	- Removed all existing GPU buffer support code and usage. All DIs now use a parameters struct.

	- Have moved tons of curve code into the base class, simplifying the child implementation classes.

	- Implemented GPU curve interpolation.

	- Removed bAllowUnnormalizedLUT. Confusing and now unnessessary. All curves do this by default.

	- Modified FNiagaraShaderMapId to use the latest FNiagaraCustomVersion::LatestScriptCompileVersion and bumped it.

	- Created NiagaraCore module and moved a few classes into it. Anything needed by both the shaders and runtime should be here.
	- Refactored DI hierarchy to base from a new UNiagaraDataInterfaceBase which is inside NiagaraCore.

	- Removed constness from many UStruct/UEnum/UClass pointers. Technically we don't ever need these to be non const so initialy coded as const. Some existing engine code however requires these be non const so had to propagate that back through our code.

	-Added piping number of vert indices per instance from the renderer down to the GPU context and CS; as a result, GPU simulated mesh emitters are working again; this will need a bit of additional work to handle multiple renderers (will need multiple DrawIndirect parameter buffers reflecting the different renderers)
	-General cleanup and prettification

	Making it possible to see the debug output if the console variables are set for shaders.

	#tests auto-tests pass

Change 4069628 by Shaun.Kime

	OpenGL is very picky about shutting down its texture buffers. We were improperly holding onto static resources and leaking OpenGLShaderResourceViews until module shutdown. Unfortunately, this is *after* the renderer has been shut down and the corresponding OpenGL managers have been deleted, causing us to call into deleted memory. By making several classes FRendererResources, we now register at the appropriate times. In several cases, since the buffers are special purpose fallbacks I moved them into helper locations that are build on demand.

	Removed FNiagaraVertexFactoryBase::DummyBuffer
	Created FNiagaraDummyRWBufferInt and FNiagaraDummyRWBufferFloat so that I could wrap several dummy RW buffers in RendererResources and TGlobalResource.
	Removed NiagaraEmitterInstanceBatcher::DummyWriteIndexBuffer

	#tests all auto-tests pass on PC and OpenGL and we can open and close OpenGL after using Niagara assets

	#jira UE-59000

Change 4069646 by Shaun.Kime

Change 3828444 by Anthony.Bills

	Add LXC container script for building third party libraries.

	The intention is that this should become the only way to rebuild the third party libraries that require system dependencies not included in the cross-compile toolchain and also to rebuild the toolchains. Other third party libraries without any system dependencies could be rebuilt via the cross-compile toolchains/UBT.

	This script has been tested running on CentOS 7 and Ubuntu 17.10.

	Buy default the x86 and x86_64 builds will be built against a CentOS 6 container (and targeting glibc 1.12) and the aarch64 and armhf builds will use an Ubuntu Ubuntu Trusty (14.04) but this is not yet complete.

	- Made it possible to override SDK passed to the toolchain.
	- Simplified the code by using the same executable names on Windows and Linux (as .exe is optional), except where File.Exists() is needed (also remove a few)
	- Some minor renames to make it clear that SystemSDK means system compiler (which otherwise may be unclear)
	- Made changes to accomodate the new debug format.

Change 3887093 by Anthony.Bills

	Add bundled mono binary for Linux.

	- Unify some of the script structure across Mac and Linux.
	- This currently uses the same mono C# assemblies as Mac to keep the additional source size down.
	- If the Mac mono version is updated, the Linux version will also need to be updated to match the same mono git revision.
	- The system version of mono can still be used by setting the UE_USE_SYSTEM_MONO env var to 1.

Change 4003226 by Michael.Dupuis

	Refactored StaticMeshInstancing to now use a command buffer to communicate with the GPU to prevent concurent access issues. It's mostly used in Editor or if runtime changes occur, otherwise the data is built and send to the GPU directly without keeping CPU copy.
	Changed how the density scaling was applied to be more optimal
	Removed UseDynamicInstanceBuffer as the concept is now irrelevant

Change 3833097 by Jamie.Dale

	Localization Pipeline Optimization

	Manifest/Archives:
	Added FLocKey to keep an immutable string and its hash. This is used in several places within manifests and archives to minimize string hashing. FLocTextHelper also now take these in its API.
	This also fixes some places where manifests were being iterated by key rather than source string (as this was causing redundant work).

	Portable Object:
	Cleaned up a lot of redundant code, changed things to use FLocKey, and simplified a lot of string manipulation to use algorithms instead (which proved to be faster).

	Asset Gathering:
	Optimized the way garbage collection runs while gathering from assets so that we avoid purging assets that we still need to gather from (or are still active dependencies). This also sorts the assets so that we can try and evict dependencies from memory as soon as possible (in much the same way that the cooker does).

	Automation:
	The gather commandlet can now take multiple configs to process. This is used by automation to avoid starting the editor several times (which can save a significant amount of start-up overhead).

  MAJOR FEATURES & CHANGES
============================

Change 3851142 by Robert.Manuszewski

	When BP clustering is enabled, make sure to add the template to the BP cluster when replacing it.

Change 3853797 by Ben.Marsh

	BuildGraph: Add a <Trace> element, which allows logging messages after the string is parsed (as opposed to the Log task, which logs them at runtime). Useful for debugging macro expansion, etc...

	Also add a -showdiagnostics parameter, to have diagnostic messages output even when running with the -listonly option.

Change 3857540 by Graeme.Thornton

	Properly process the uexp file for a umap asset when generating a pak patch. Stop those uexp files being included in the patch even when they haven't changed

Change 3860062 by Steve.Robb

	Fix for FString::Reset()'s buffer not being an empty null-terminated string (affects FString::ParseIntoArray, for example).

Change 3860138 by Steve.Robb

	Fix for FString::ParseIntoArray() for when string memory has been allocated but has no characters.

Change 3860273 by Steve.Robb

	Tidy up of FHotReloadClassReinstancer::FCDOWriter to not do stuff in constructors.

Change 3863203 by Steve.Robb

	Crash fix for UObjects whose constructors are defined as = default;, which would re-null the UObject state (ClassPrivate, OuterPrivate etc.).

	See: https://udn.unrealengine.com/questions/412930/crash-due-to-default-constructor.html

Change 3864588 by Graeme.Thornton

	Crypto Keys Improvements
	 - Removed UAT command line params for encryption. Centrally configured by the editor settings now.
	 - UAT staging now creates a small json file containing the keys and settings used for encryption and signing and stores it in the build metadata
	 - Minor refactoring of UAT encryption processing to use the new cryptokeys json file
	 - UnrealPak can be told to get its encryption settings from a json crypto file with the "-CryptoKeys=<filename>"
	 - UnrealPak can now accept a "PatchCryptoKeys=<filename" parameter which gives it a filename to a cryptokeys json file that it can use to unpack the patch reference paks

Change 3864691 by Robert.Manuszewski

	Don't add objects that are in root set to GC clusters to prevent them from keeping the clusters alive forever.

Change 3864744 by Robert.Manuszewski

	Added the ability to get the actual filename of the log file FOutputDeviceFile writes to.

Change 3864816 by Graeme.Thornton

	TBA: Minor formatting improvements to textasset commandlet

Change 3868939 by Graeme.Thornton

	TBA: If -outputPath isn't supplied to TextAsset commandlet, output converted files to the {ProjectSaved}/TextAssets directory

Change 3869031 by Graeme.Thornton

	TBA: Changed timing logs in TextAsset commandlet to be Display so we can see them in the EC log

	Class cast flags and property flags are now visible in the debugger.

Change 3871863 by Robert.Manuszewski

	Serializing object will now be passed to GC so that it can be logged in case the referenced objects is garbage.

Change 3874413 by Steve.Robb

	Algo::MinElement and Algo::MaxElement, for finding the minimum and maximum element in a range, and *By versions which take projections.
	TRangePointerType moved to its own file and used in Algo::MinElement and Algo::MaxElement.

Change 3874457 by Ben.Marsh

	When spawning child processes, only allow them to inherit the writable ends of the stderr and stdout pipe. Fixes an issue related to AutomationTool hanging when the editor closes after running automation tests.

	The editor launches ADB.EXE (Android Debug Bridge) on editor startup, which forks itself to initialize a server. Even though the child process has its own stdout and stderr pipes, it also inherits the pipes for the editor. When run from C#, as we do for automation tests, Process.WaitForExit() waits for all pipes to be closed before returning. This can't happen if the forked ADB instance still has a reference to the editor's pipes.

Change 3876435 by Robert.Manuszewski

	Don't add root set objects to level actor container to prevent situations where clusters are kept alive forever

Change 3878762 by Robert.Manuszewski

	Fixing potential LinkerLoad leak when a package that still has a linker associated with it is being destroyed.

Change 3878850 by Robert.Manuszewski

	SerializePreloadDependencies will now serialize raw data into the array instead of serializing one element at a time to speed up serialization performance.

Change 3881331 by Graeme.Thornton

	TBA: SavePackage rejigged to write all header information in terms of FStructuredArchive, with all exports written through an FArchive adapter

Change 3886983 by Ben.Marsh

	UGS: Fix notification window not expanding to fit long captions.

Change 3887006 by Ben.Marsh

	UGS: Change modal dialog to regular window style to avoid weird alignment issues under Windows 10.

Change 3887500 by Ben.Marsh

	UGS: Add support for grouping build badges by a prefix. Badges such as "Foo:Bar1", "Foo:Bar2" will be grouped together (with "Foo:" stripped from the displayed badge names).

	Also add a separate column showing the type of each change, rather than including it in the CIS column, and change badges to a more angular Windows 10 style.

Change 3887513 by Ben.Marsh

	UGS: Fix badge text drawing outside the clipping bounds.

Change 3888010 by Josh.Engebretson

	Fix UVS logging to UnrealVersionSelector/Saved/Logs and instead use project's log path
	#jira none

Change 3888418 by Ben.Marsh

	UGS: Add a cache for computed badge layout information. Improves responsiveness when redrawing.

Change 3889457 by Steve.Robb

	GitHub #4457 : Display abbreviations properly when converting FNames to display string

	#jira UE-54611

Change 3889547 by Ben.Marsh

	UGS: Add an extensible method for adding arbitrary badges to the right of the "description" column, by running a regular expression over the changelist description.

	Epic uses a "#tag" style annotations in changelist descriptions and Perforce triggers to verify them. "#jira" is used to link a changelist to an issue tracked in Jira, for example. A matcher to add a badge next to every changelist with a #jira tag, and link to the corresponding issue in Jira, could be set up with an addition to the project's Build/UnrealGameSync.ini file like this:

	[Badges]
	+DescriptionBadges=(Pattern="(?i)#\\s*jira\\s*:?\\s+([A-Za-z]+-[0-9]+)", Name="$1", Group="Jira", Color="#c0c0c0", HoverColor="#e0e0e0", Url="https://jira.it.epicgames.net/browse/$1")

	The "Pattern" attribute specifies the regex to match, and may capture portions of the matched text to be substituted later. "Label" specifies the label to appear on the badge. "Group" specifies an arbitrary identifier used to group related badges together rather than separating them with whitespace. "Color" and "HoverColor" specify hex RGB colors for the badges. "Url" specifies the path to open with a C# Process.Open call if the badge is clicked.

Change 3889726 by Ben.Marsh

	UGS: Fix description badges that don't have any associated URL.

Change 3889995 by Ben.Marsh

	UGS: Fix issue where popup menus can create top level windows in the taskbar. Seemlingly caused by capturing mouse before the window has been activated - removed capture code, and replaced with handling of OnMouseLeave() event instead.

Change 3890007 by Ben.Marsh

	UGS: Add a caption underneath the project logo which shows the current stream, to make it more obvious.

Change 3890057 by Ben.Marsh

	UGS: Fix repainting glitch when resizing window; bounds for status panel lines was not being reset correctly.

Change 3891069 by Robert.Manuszewski

	Fixing a crash in MallocBinned2 when running with malloc profiler enabled.

Change 3891084 by Steve.Robb

	Back out changelist 3881331 because it's causing cook errors.

Change 3891100 by Ben.Marsh

	UGS: Add support for a per-branch "message of the day"-style feature. Messages can be specified in a project's config file in Perforce (eg. <ProjectDir>/Build/UnrealGameSync.ini) as follows:

	[//UE4/Main/Samples/Games/ShooterGame.uproject]
	Message=:alert:  Lockdown for fixes is **5pm on Friday**. Only fixes for the 2.0 release should be submitted to this branch. [34 issues](https://jira.it.epicgames.net) are remaining as of 2/15.

	A limited subset of Markdown is supported: [web links](http://www.google.com), *italic*, _italic_, **bold**, __bold__. Icons will be supported through :icon: syntax; the only icon currently available is :alert:

Change 3891346 by Steve.Robb

	TSharedPtr::operator bool, and some usage of it.

Change 3891787 by Steve.Robb

	Fix for buffer overflow in FDebug::LogFormattedMessageWithCallstack().

Change 3892379 by Ben.Marsh

	UGS: Fix notification window containing the group fix for each build type.

Change 3892400 by Ben.Marsh

	UGS: Shrink the size of the alert panel.

Change 3892496 by Ben.Marsh

	UGS: Dim badges for changes which aren't eligable for syncing.

Change 3893932 by Steve.Robb

	Re-removal of SetShouldHandleAsWeakRef, which was originally removed in CL# 3437205.

Change 3895872 by Ben.Marsh

	UGS: Show the stream name in tab labels by default.

Change 3896366 by Ben.Marsh

	UGS: Automatically resize columns when the main window is resized, and allow specifying desired column widths for projects that have a large number of CIS badges.

	Columns are now resized proportionally, clamped to a minimum size. Columns will automatically expand up to a desired maximum size, though can be explicitly resized larger if necessary. Columns will not be resized if they are already larger than the window can show, or smaller than the window has space to show.

Change 3896367 by Ben.Marsh

	UGS: UI tweaks - change and time columns are now centered, "Unknown" badge is displayed until a change's type has been determined, increase height of status panel.

Change 3896425 by Ben.Marsh

	UGS: Speculative fix for race condition on clients displaying "under investigation" state. If the DB event is received before a change where an investigation is cancelled is polled from Perforce, we will exclude the resolve event from the list of active investigations.

Change 3896461 by Ben.Marsh

	UGS: Add an option to allow setting a tint color to be applied to the status panel, to allow identifying streams more easily. To use, add a setting similar to the following to a project's Build/UnrealGameSync.ini file:

	[//UE4/Main/Samples/Games/ShooterGame/ShooterGame.uproject]
	StatusPanelColor=#dcdcf0

Change 3899530 by Ben.Marsh

	Add unified syntax for overriding branch specific settings. Checks branch settings first, then [Default] section.

Change 3901164 by Ben.Marsh

	UGS: Add a class to store all the resources for the status panel.

Change 3901165 by Graeme.Thornton

	TBA: Attempt #2 at submitting the text asset saving code. SavePackage rejigged to write all header information in terms of FStructuredArchive, with all exports written through an FArchive adapter. Minimal amount of structured archive serialization functions added to allow this data to be written

Change 3901301 by Ben.Marsh

	UGS: Add support for reading the latest version of the project config file from Perforce. Some settings should be read depending on the CL you are synced to (eg. build steps), whereas others (MOTD, branch status) should always use the latest version. Will read the local version if checked out, to allow testing local changes.

Change 3902454 by Ben.Marsh

	UGS: Fix logo not being redrawn in the correct position when starting to sync.

Change 3903416 by Ben.Marsh

	UGS: Group badges explicitly through INI file rather than by expecting name to contain ':'.

Change 3904154 by Josh.Engebretson

	Adding Breakpad to ThirdParty sources (Git Commit: 49907e1c3457570f56d959ae26dec6c3a5edd417 https://chromium.googlesource.com/breakpad/breakpad)
	#jira UE-55442

Change 3904648 by Ben.Marsh

	UGS: Remove files from the workspace that are excluded by the sync filter.

	The user's config file stores a hash of the last sync filter. During syncing, if this hash doesn not match the previous value, we enumerate all the files in the #have list and remove anything masked out by the filter.

	#jira UE-47335

Change 3905442 by Steve.Robb

	Change of the ConvertFromType() multi-bool return value to a more descriptive enum.
	Some return values here do not make sense - this is because the existing logic is being preserved and will be fixed in a separate change.

Change 3905629 by Ben.Marsh

	UGS: Fix race condition between two child processes starting on different threads, and inheriting the other's intended stdout/stderr pipes. This prevents pipes being closed when one of the child processes shuts down, and causes waits on the read ends of those pipes to continue indefinitely.

Change 3906447 by Steve.Robb

	Rename EConvertFromTypeResult enumerators.

Change 3906574 by Steve.Robb

	Crash fix for container conversion failure during tagged property import.

Change 3909255 by Daniel.Lamb

	Fixed issue with DLCpackaging crashing on windows
	#jira UE-42880

Change 3909324 by Steve.Robb

	Use switch statement instead of repeated if/else.

Change 3909525 by Ben.Marsh

	UGS: Use the StudioEditor target when syncing content-only Enterprise projects.

Change 3911754 by Daniel.Lamb

	Fix for building pak patches.

	#jira UE-55340

Change 3911942 by Robert.Manuszewski

	Fixing an ensure when MediaPlayer is being constructed from any thread other than the main one.

Change 3913067 by Ben.Marsh

	UGS: Allow workspace sync filter categories to re-enable categories that are disabled by the global filter.

Change 3913209 by Ben.Marsh

	UGS: Fix incorrect target name when compiling Enterprise projects.

Change 3917358 by Steve.Robb

	Fix for GetLen(FString).

Change 3919610 by Ben.Marsh

	Put data for CrashReportClient in a PAK file of its own (under Engine/Programs/CrashReportClient/Content/Paks/CrashReportClient.pak). There are a large number of small files required for it to run with loose files, which takes a lot of space on disk (due to cluster sizes), and is unweildy to move around.

	CrashReporter UFS files are tracked in a separate dictionary to regular UFS files to allow construction of the additional PAK file.

Change 3921002 by Ben.Marsh

	UGS: Add option for syncing all projects in a branch. Off by default. Also add support for masking in additional paths to be synced (eg. one or two extra projects).

Change 3921008 by Ben.Marsh

	UGS: Prevent pause waiting for mutual exclusivity when syncing precompiled binaries. We don't need to generate project files or build, so there's no need to wait in line.

Change 3921906 by Steve.Robb

	New interpolation functions for quaternions.

	https://udn.unrealengine.com/questions/419028/quaternion-interp-to-functions.html

Change 3921978 by Graeme.Thornton

	TBA: Make "Loader" member of FLinkerLoad private to prevent use outside of FLinkerLoad. This archive could be something unexpected if the linker is for a text asset package, so we need to stop people accessing it.

Change 3924520 by Graeme.Thornton

	UnrealPak: Improve encryption summary log messages

Change 3924522 by Graeme.Thornton

	UAT: Add *Encryption.ini to the list of auto-blacklisted config filenames

Change 3924604 by Graeme.Thornton

	UnrealPak: If encryption keys are parsed and fail the encrypt/decrypt test, throw a fatal error. The exectutable will have those same keys embedded so there is no point allowing the paks to be created with broken keys.

Change 3924638 by Graeme.Thornton

	Crypto: Improvements to parsing of old fashioned encryption.ini settings:
	 - AES keys that are too long or short (need to be 32 bytes) will now emit a warning when being parsed, and be truncated or expanded before adding to the crypto settings.
	 - Signing keys will emit an error when they are too long (>64bytes)
	 - Unrealpak will still assert when invalid settings are passed via the other mechanisms (command line or -encryptionini mode). Settings via the crypto json file should now be sanitized and not cause issues

	#jira UE-55080

Change 3924747 by Steve.Robb

	Fix for degrees.

Change 3925459 by Chad.Garyet

	Adding check to not to attempt to delete autosdk workspace if it doesn't already exist.

Change 3926703 by Ben.Marsh

	BuildGraph: Include the path to the XML file when displaying an XML parse error.

Change 3926917 by Ben.Marsh

	UBT: Allow overriding the name of the UE4 solution on a branch-specific basis. Useful for switching between multiple UE4 workspaces. Also add support to the editor and UGS for opening the correct solution (determined via a text file saved to Engine/Intermediate/ProjectFiles).

	Set the solution name using an entry in BuildConfiguration.xml as follows:

		<ProjectFileGenerator>
			<MasterProjectName>UE4_Main</MasterProjectName>
		</ProjectFileGenerator>

Change 3927683 by Graeme.Thornton

	UAT: When building with chunk installs enabled, don't generate the master manifest from each pak creation thread. Just do it once after all pak files have been created. Avoids intermittent crash with multiple threads trying to write the same json file.

Change 3928111 by Ben.Marsh

	UBT: Add an option <bMasterProjectNameFromFolder> which allows setting the solution name based on the folder that it's in.

Change 3928926 by Ben.Marsh

	BuildGraph: Add support for enumerating content copied by the <CsCompile> task. Also add support for invoking methods on string properties.

Change 3931041 by Graeme.Thornton

	TBA: Add option to textasset commandlet to also include engine content in a resave

Change 3931043 by Graeme.Thornton

	TBA: Redirect some more FArchive members in FArchiveProxy

Change 3931913 by Ben.Marsh

	UGS: Do not create a modal dialog if a scheduled sync is unable to run because the editor is open, and do not run the editor after a scheduled sync.

	#jira UE-47368

Change 3932419 by Ben.Marsh

	UGS: Allow selecting which projects to sync on schedule. Any projects not already opened at the time the schedule is triggered will be opened first.

	#jira UE-33541

Change 3932483 by Ben.Marsh

	PR #3949: UnrealGameSync: Add environment path field to custom BuildStep (Contributed by frankie-dipietro-epic)

	UGS: Add an error dialog when trying to clean the workspace before closing the editor.

	#jira UE-42308

Change 3932679 by Ben.Marsh

	UGS: Add the date/time to the end of the sync log.

	#jira UE-33540

Change 3932705 by Ben.Marsh

	UGS: Prompt to close the editor before allowing the user to enter a changelist to sync to, when syncing to a specific changelist.

	#jira UE-53182

Change 3933318 by Ben.Marsh

	UGS: Detect more programs running before allowing a sync to start, show a dialog listing them, and add an option to ignore if necessary.

	#jira UE-33535, UE-53914

Change 3933840 by Graeme.Thornton

	TBA: When loading assets, only use structured archive adapters for exports when loading text files.

Change 3936040 by Ben.Marsh

	UGS: Rewrite application lifecycle to fix issues with scheduled syncs on background windows not activating, and window jumping to the front after auto-update.

	Now uses a custom application context to allow creating separate 'main' windows (first the "opening projects" form, then the regular form), and does not require any forms to be shown in order to be updating in the background.

	#jira UE-52870

Change 3940230 by Robert.Manuszewski

	Fixes for FilenameToLongPackageName crashes when runnign commandlets

Change 3940240 by Graeme.Thornton

	Automated cycling of encryption and signing keys

Change 3940243 by Graeme.Thornton

	UAT: CryptoKeys automation script

Change 3940321 by Ben.Marsh

	UGS: Add a "Bisect" mode for regressing bugs between a certain range of changes. To use, select a range of changes by holding down the shift key or individual changes by holidng the control key, then right click and select "Bisect these changes". Individual changes in the list can be marked as "Bisect: Pass" or "Bisect: Fail" from the context menu, and syncing will find the next change in the center of the range.

Change 3940538 by Ben.Marsh

	UBT: Always determine whether a project is a foreign project or not from the valid .uprojectdirs entries, rather than relying on the user passing -game on the command line.

Change 3941285 by Gil.Gribb

	UE4 - Removed PRAGMA_DISABLE_OPTIMIZATION from PlatformFileCommon.h. It was an oversight.
	#jira none

Change 3942404 by Graeme.Thornton

	Pak Signing:
	 - Unify naming of pak precacher and signedarchivereader signature check functions to make it easier to search for them in crash reporter
	 - Format the signedarchivereader output to match the pak precacher
	 - When signedarchivereader detects a signature check, do the same master signature hash check that the pak precacher does to confirm that the .sig file contents haven't been corrupted since load.
	 - Add PAK_SIGNATURE_CHECK_FAILS_ARE_FATAL guarded exit to signedarchivereader signature failure
	 - Optimization for pakprecacher signature checks. Instead of locking the cached files mutex for every decoded signature, take a local copy in blocks of 16. Only re-lock if we need more. Grab the initial batch when setting up. In most cases, reduces the number of locks to 1 per signature check call.

Change 3947359 by Graeme.Thornton

	TBA: Fixes to loading code to allow bulk data to get a pointer from its loader archive to an archive that it can load from at a later date. For binary archives, this is just a pointer back to the same archive, but for text assets it is a pointer to a "child reader" which maintains its own structured archive that is scoped to the current location in the file.

Change 3947360 by Graeme.Thornton

	TBA: Added RoundTrip mode to text asset commandlet. Performs determinism tests in project assets to see whether they save deterministically to binary and text files, and also when they are ping-ponged between the two formats.

Change 3954694 by Ben.Marsh

	BuildGraph: Add support for user-defined macros, which can contain a list of buildgraph commands and be expanded within a node. Example script in Engine/Build/Graph/Examples/Macros.xml.

	To define a Macro, use the syntax:

		<Macro Name="MyTestMacro" Arguments="PrintFirstMessage;PrintSecondMessage" OptionalArguments="PrintThirdMessage">
			<Log Message="First message" If="$(PrintFirstMessage)"/>
			<Log Message="Second message" If="$(PrintSecondMessage)"/>
			<Log Message="Third message" If="'$(PrintThirdMessage)' == 'true'"/>
		</Macro>

	To expand a macro, use the syntax:

		<Expand Name="MyTestMacro" PrintFirstMessage="true" PrintSecondMessage="true"/>

	An error will be thrown if any required arguments are missing. Optional arguments default to empty if not specified.

	Tasks within a macro are validated by the schema at the point of definition using the same rules as apply to a <Node> element, but properties are not evaluated until the macro is expanded. This allows macros to get and set properties in scope at the point that it is expanded. Local properties that are introduced within a macro do not otherwise leak to the scope that they are expanded.

	TBA: Text asset loading/saving work
	 - Start using FStructuredArchive flavours of UObject Serialize functions when loading and saving exports.
	 - Only use FStructuredArchive interface for text assets, and for classes that have the CLASS_MatchingSerializers which tells us that the class can serialize to both FStructuredArchives and FArchives.
	 - Add GetCacheableArchive to FArchive, which allows transient archives to return a pointer to another archive that will outlive it. Used by bulk data to get a pointer to an archive that can be held and used at a later time to lazy load things. For text assets where the bulk data might be held inside a base64 encoded FArchiveFromStructuredArchive block, we can't dynamically seek back to that location after the on-stack wrapper has been destroyed after the original serialize, so this will return null. For binary assets, we just return a pointer to the same binary archive which can be used freely.

	UGS: Fix child processes being unable to spawn other child processes with the CREATE_BREAKAWAY_FROM_JOB flag, to add them to their own job objects.

	In Windows 7 or earlier job objects cannot be nested, so child processes have to create separate job objects and spawn processes with CREATE_BREAKAWAY_FROM_JOB to be able to add them. This fails unless parent process' job object was created with JOB_OBJECT_LIMIT_BREAKAWAY_OK.

	* Changed text asset extensions to .utextasset and .utextmap. Couldn't go with the favourite .uasset.json because our various path functions (FPaths::GetCleanFilename etc.) will only strip one layer of extension, so leave a bogus filename.
	* Relaxed a few checks in structured archive where it was checking for field reentrance, which isn't a problem for loading.
	* Changed FArchiveFromStructuredArchive to not load all referenced objects at construction time. This introduced some changes to load order which don't work in the engine. Object names are resolved at the point that a reference to them is serialized from the main data block, same as with legacy archives.

Change 3921587 by Steve.Robb

	Static asserts inside ensureMsgf() macros to prevent them being passed invalid arguments or non-literal formatting strings.
	Fixes for various misuses.

	#jira UE-55681

Change 3942873 by Ben.Marsh

	UBT: Allow link time code generation on any configurations where bAllowLTCG is set to true. Microsoft platforms were previously only allowing this option in shipping; the target can decide when to enable it or not.

Change 3944629 by Graeme.Thornton

	Merging back a couple of fixes from Fortnite
	 - Extra parenthesis around some calculations in the pakprecacher
	 - Changed FChunkCacheWorker::DoSignatureCheck() back to ::CheckSignature()
	 - Added documentation for build script crypto options

Change 3945381 by Ben.Marsh

	Disable warning C4770 on Windows (partially validated enum 'xxx' used as index), which occurs when enabling LTCG. Can't find a reference online for this warning, but I suspect it's due to LTCG allowing the compiler to trace code paths where we don't validate that an enum is a known value.

Change 3968969 by Steve.Robb

	Fixes to incorrect uses of FScriptMapHelper and FScriptSetHelper, which weren't accounting for gaps in the sparse array.

Change 3969417 by Ben.Marsh

	Make Visual Studio 2017 the default compiler for UE4 projects, and add support using Visual C++ toolchains from an AutoSDKs.

	Also add support for selecting a specific toolchain version to use through the WindowsPlatform.CompilerVersion property, which can be configured via a Target.cs files or BuildConfiguration.xml (eg. <WindowsPlatform><CompilerVersion>14.13.26128</CompilerVersion></WindowsPlatform). As well as allowing a specific version number, you can always use the latest toolchain by setting it to "Latest".

Change 3972443 by Ben.Marsh

	Change build scripts to allow running any steps on non-compile workspaces. Setup Dev-Core to just use a non-compile Win64 workspace for everything.

Change 3977198 by Ben.Marsh

	Remove INI file override for editor stack size on Windows. This is rarely valid since editor targets share build products with other games by deafult. Fix to add linker response file as prerequisite exposed targets overriding this as a bug.

Change 3979632 by Ben.Marsh

	Consolidate codepaths for embedding versioning information in the engine. Engine/Build/Build.version is now the authoritative place to read version information; Engine/Source/Runtime/Launch/Resources/Version.h no longer includes macros for the current branch and changelist.

	* Settings from Build.version are compiled into the (tiny) BuildSettings module via macros set in BuildSettings.build.cs, which is used to initialize version information inside the engine at runtime.
	* The IsPromotedBuild value is now set to zero by default (but set to 1 by the UpdateLocalVersion UAT command).
	* The -Licensee argument to the UpdateLocalVersion UAT command, and the IsLicenseeVersion setting for UnrealGameSync, is determined automatically by looking for the Engine/Build/NotForLicensees/EpicInternal.txt file. This path is not visible to licensees.

Change 3981738 by Ben.Marsh

	Move utility classes for filtering files and matching wildcards into DotNETUtilities.

Change 3983888 by Steve.Robb

	Warning C4868 disabled, about evaluation order of braced initializer lists.

	https://udn.unrealengine.com/questions/426081/help-with-error-c4868-braced-initializers.html

Change 3984019 by Steve.Robb

	FString::Printf formatting argument checking added.
	Vararg support for FText::Format.
	All remaining usage fixed.

Change 3985502 by Steve.Robb

	Change to TFunction debugger visualization to allow right-clicking on the [Lambda] and selecting 'Go To Source Code'.

Change 3985999 by Graeme.Thornton

	TBA: Serialize function generation for FArchive and FStructuredArchive overloads on a UObject, using UHT.
	 - Adds a restriction that UObject::Serialize() functions MUST be declared outside of any conditional compilation directives, except for WITH_EDITORONLY_DATA

Change 3986461 by Ben.Marsh

	Fixup lots of platforms not adding response files as a prerequisite.

	This can cause incremental builds to fail if input files/compile arguments change, because the action graph does not know that the response file being updated invalidates the build artifacts.

Change 3990081 by Ben.Marsh

	Remove custom output formatters for errors and warnings. These are not well supported by different executors, and cause fences between actions with the same formatter with external executors like XGE.

	Clang supports -fdiagnostics-format=msvc for all platforms, which should do a better job than our crude attempts at regexing errors (causing botched output in some cases).

Change 3996714 by Chad.Garyet

	UGSRestAPI, conversion of UGS to use it.

	#jira none

Change 4008287 by Ben.Marsh

	UBT: Change the engine to use the Windows 10 SDK by default.

	Also add support for switching between specific Windows SDK versions. The WindowsPlatform.WindowsSdkVersion property in the target rules can be used to select a desired version, which can also be configured by the <WindowsPlatform><WindowsSdkVersion>Foo</WindowsSdkVersion></WindowsPlatform> parameter in the BuildConfiguration.xml file.

	The version of Windows to target (ie. the WINVER macro) can be modified by setting WindowsPlatform.TargetWindowsVersion. The default is 0x0601 (Windows 7).

Change 4008516 by Chad.Garyet

	- Adding support for both SQLite and MsSql
	- API now reads from only MsSql, but writes to both
	- Added support for POST to CIS for badges
	- PostBadgeStatus now writes out via API Url rather than a direct connection to the DB

	#jira none

Change 4010296 by Chad.Garyet

	Moving SQLite db initilization into Application_Start.  An exception thrown creating or seeding the db will unload the entire AppDomain and all pages will return a 404.
	#jira none

Change 4024045 by Ben.Marsh

	Set the list of supported target platforms for OnlineSubsystemGameCircle.

	#jira UE-57887

Change 4031014 by Ben.Marsh

	UAT: Add a WhitelistDirectories list in DefaultEngine.ini, which allows specifying folders that can be staged despite having restricted folder names.

	#jira UE-53646 Reimplement CR #4369 so setting a Class blueprint variable to a blueprint class will correctly allow unloaded blueprint children to be selected in the picker
	Added FName defines to FBlueprintTags for the asset registry tags used for unloaded blueprints, and removed the ParentClassPackage tag as it was redundant with ParentClass
	Fixed it so Soft Class Reference properties can be set back to none with the picker

	Add DevelopmentAlwaysCook setting to the asset manager cook rule, this works like AlwaysCook in development and like NeverCook in production. DevelopmentCook works like Unknown in development

Change 3982762 by Mieszko.Zielinski

	PR #4614: Fix UBTTask_RotateToFaceBBEntry when trying to face a position where i. (Contributed by Goutye)

	I've improved the original PR by relaxing condition constraints, and removing some unnecessary vector normalization (since FVecotr::CosineAngle2D normalizes the input parameters anyway).

Change 3990826 by Phillip.Kavan

	Fix existing placements of nativized Blueprint actors with a nonzero (legacy) root component scene transform at the CDO level.

	This corrects a long-standing issue that was introduced back in 2947488.

	Change summary:
	- Modified AActor::PostSpawnInitialize() to zero out RelativeLocation and RelativeRotation when spawning actors with a native scene root inherited from a converted Blueprint class.
	- Modified FNonativeComponentData to remove the HandledAsSpecialProperty() override for skipping the RelativeLocation and RelativeRotation properties on root components when emitting code to initialize the CDO for a converted Actor BP with a non-native root component.

	#jira UE-50452

Change 3993174 by mason.seay

	Cleared out unnecessary BP logic

Change 3994370 by Ben.Zeigler

	ObjectWriter should not reset the soft object weak pointer, it should be a const operation

Change 3996921 by Ben.Zeigler

	#jira UE-57288 Improve ensures for invalid primary asset types, it only complains if type is set and gives a better error

Change 3997164 by Dan.Oconnor

	Don't purge classes until they are recompiled and relink all child classes immediately after a blueprint generated class has changed. This allows iterative compilation logic to behave as it did before the compilation manager

	#jira UE-57656

Change 4001338 by Dan.Oconnor

	Fix reinstancing bug introduced in 3591939 which could cause some reinstanced objects to have references within them replaced. If the object in question was an actor it could take ownership of components owned by another actor and destroy them, resulting in a crash when the other actor tried to use its components

	#jira UE-57335

Change 4001400 by Marc.Audy

	Per https://udn.unrealengine.com/questions/407745/childactorcomponent-and-modifications-to-component.html don't redirect or reset loaders when renaming components as part of the component instance data cache.

	Fix random crashes when running multiple global blueprint search tabs in parallel just after editor launch.

	Change summary:
	- Refactored global FiB APIs to use thread-safe shared pointer types when referencing imaginary Blueprint data, which is a shared resource.
	- Modified FFindInBlueprintSearchManager::ContinueSearchQuery() to ensure that parsing imaginary Blueprint data only happens on a single thread.
