==========================
MAJOR FEATURES + CHANGES
==========================

Change 3252833 on 2017/01/10 by Ori.Cohen

	Refactor constraint so that it can be used for external solvers. (Copying //Tasks/UE4/Dev-ImmediateModePhysics to Dev-Framework (//UE4/Dev-Framework))

Change 3256288 on 2017/01/12 by Ori.Cohen

	Undo constraint refactor as we found a way around it and it made the code much harder to read/debug

Change 3373195 on 2017/03/30 by Mike.Beach

	For nativization, changing it so we key off of the target platform-info struct instead of the platform (in preparation for defining the nativized plugin's platform whitelist).

Change 3381178 on 2017/04/05 by Dan.Oconnor

	Make sure we don't inherit the NATIVE func flag when generating skeleton functions, also make sure all bojects outer'd to the skeleton class are marked transient
	#jira UE-43616

Change 3381532 on 2017/04/05 by Marc.Audy

	(4.16) Fix various cases where built lighting on child actors could be lost when loading a level
	#jira UE-43553

Change 3381586 on 2017/04/05 by Mike.Beach

	Now generating TArrayCaster conversions for nativized UClass arrays that need it (to handle different TSubclassOf arrays).

	#jira UE-42676, UE-43257

Change 3381682 on 2017/04/05 by mason.seay

	Some more changes to test map

Change 3381844 on 2017/04/05 by Dan.Oconnor

	Match existing logic for CPF_ReturnParm/CPF_OutParm. Fixes compilation error in BP_TurbineBlades when using compilation manager

Change 3382054 on 2017/04/05 by Zak.Middleton

	#ue4 - Optimize CharacterMovementComponent::GetPredictionData_Client_Character() and GetPredictionData_Server_Character() to remove virtual calls.

	#jira UE-30998

Change 3382703 on 2017/04/06 by Lukasz.Furman

	fixed missing links between navmesh polys when there are more than 4 neighbor connections
	#jira UE-43524

Change 3383357 on 2017/04/06 by Marc.Audy

	(4.16) Make SetHiddenInGame propagate consistently with SetVisibility
	#jira UE-43709

Change 3383359 on 2017/04/06 by Dan.Oconnor

	Fix last errant SKEL reference when cooking Odin

Change 3383591 on 2017/04/06 by Mike.Beach

	Prevent users from setting object variables as 'config' properties (disallowed by UHT). This prevents some errors that could happen later when users nativize the Blueprint.

	#jira UE-42085

Change 3384762 on 2017/04/07 by Zak.Middleton

	#ue4 - Fix SpringArmComponent not restoring relative transform when bUsePawnControlRotation is turned off. Fixes the editor interaction ignoring transform of the component in the viewport after bUsePawnControlRotation is toggled on then off, since by then the world transform had been overwritten (from tick in editor) and nothing would drive transform changes from the editable value.

	Toggling bUsePawnControlRotation off at runtime now restores the rotation to the initial relative rotation, not stomping it with the current pawn rotation, allowing toggling between the editable/desired base rotation and the control rotation.

	#jira UE-24850

Change 3384948 on 2017/04/07 by Dan.Oconnor

	Prevent GForceDisableBlueprintCompileOnLoad from causing all sorts of badness when dependencies are loaded as part of a Diff operation. Instead of setting a global flag we flag the package as LOAD_DisableCompileOnLoad

Change 3385267 on 2017/04/07 by Michael.Noland

	Graph Editing: Pushed some node diffing code down from UAIGraphNode into UEdGraphNode so nodes with details panel properties will diff correctly (e.g., various animation nodes and BP switch nodes)

	#jira UE-21724

Change 3385473 on 2017/04/07 by Phillip.Kavan

	#jira UE-43067 - Fix broken pin wires after an Expand Node operation, along with some misc. cleanup.

	Change summary:
	- Fixed to use correct string for "Expand Node" transaction name.
	- Modified FBlueprintEditor::OnExpandNodes() to consolidate some redundant code.
	- Fixed to generate a unique node GUID for cases where the source graph is not removed after expansion.

Change 3385583 on 2017/04/07 by Dan.Oconnor

	Handle CreatePropertyOnScope nullptr return values (happens for structs missing a struct property)

	#jira UE-43746

Change 3386581 on 2017/04/10 by Michael.Noland

	Blueprints: Further hardening FBlueprintActionInfo::GetOwnerClass()
	#jira UE-43824

Change 3386615 on 2017/04/10 by Marc.Audy

	Instanced properties can now properly be set on a per-instance basis in blueprint added components.
	#jira UE-42066

Change 3387000 on 2017/04/10 by Marc.Audy

	Fix includes for CIS

Change 3387229 on 2017/04/10 by mason.seay

	More changes to TM-Gameplay

	Added Save Game test (with blueprint)

	Tick Interval test (with blueprint)

	BP logic cleanup

	Level organization

Change 3388437 on 2017/04/11 by Mike.Beach

	Adding support for map/set literals in the backend (so you can use set nodes for structs containing sets/maps, without having to connect a RHS input - resets to struct defaults).

	#jira UE-42617

Change 3388532 on 2017/04/11 by mason.seay

	Submitting latest changes for crash repro

Change 3389026 on 2017/04/11 by Ben.Zeigler

	Performance and bug fixes for incremetal cooking with asset registry, duplicate of several changes made on //Fortnite/Main
	Fix it so AssetRegistry.ScanPathsAndFilesSynchronous won't scan subdirectories inside already scanned directories, this cuts down on the number of cache files
	Fix 2 second stall when shutting down AssetSourceFilenameCache if it had never been previously created

Change 3389163 on 2017/04/11 by Ben.Zeigler

	#jira UE-42922 Fix it so connecting function input node output pins does not clear default value, we only want to clear the value when connecting an input pin. Properly testing this fix depends on UE-43883

Change 3389205 on 2017/04/11 by Marc.Audy

	Protect against a handful of GEditor usages that can now be hit in standalone

Change 3389220 on 2017/04/11 by Marc.Audy

	Don't borrow ClassWithin to masquerade as ParentClass during compilation and instead just set the super struct immediately

Change 3389222 on 2017/04/11 by Michael.Noland

	Framework: Adding a cvar (t.TickComponentLatentActionsWithTheComponent) to allow users to revert to the old behavior on when component latent actions tick
	- Non-zero values behave the same way as actors do, ticking pending latent action when the component ticks, instead of later on in the frame (default behavior in 4.16 and beyond)
	- Prior to 4.16, components behaved as if the value were 0, which meant their latent actions behaved differently to actors

	This CVar will be removed in a future version, defaulting to on

	#jira UE-43661

Change 3389276 on 2017/04/11 by Marc.Audy

	Spelling fix and NULL to nullptr

Change 3389303 on 2017/04/11 by Mieszko.Zielinski

	Made sure AIController::Posses doesn't get called when compiling Pawn BP #UE4

	#jira UE-43873

Change 3390215 on 2017/04/12 by mason.seay

	Removed some tests, will need further review

Change 3390638 on 2017/04/12 by Mike.Beach

	Generalizing the omission of the CoerceProperty (in EmitTerm) - previously we were only omitting properties for our custom array lib. For wildcards, a coerce property should not be used as its type will not match.

	NOTE: There is a slight behavior change in UEdGraphSchema_K2::ConvertPropertyToPinType(), as it will return 'wildcard' for params marked as 'ArrayTypeDependentParams' (previously would have returned 'int').

	#jira UE-42747

Change 3390774 on 2017/04/12 by Ben.Zeigler

	#jira UE-43911 Fix several issues with saving a runtime asset registry containing redirectors that caused crashes in cook on the fly. Don't resolve redirectors on incoming links because it will make a circular link, and fix an issue where chained redirectors would break the for loop iteration and return a bad dependency
	Fix it so the asset registry written out at the beginning of CookOnTheFly uses the registry generator, otherwise it will include all of the stripped editor only tags

Change 3390778 on 2017/04/12 by Ben.Zeigler

	Fix UCookOnTheFlyServer::CollectFilesToCook to check for initial unsolicited packages up front. This is required in iterative mode because it may skip cooking all explicit packages and thus miss a new startup loaded package

Change 3390782 on 2017/04/12 by Ben.Zeigler

	Change RunProjectCommand to not imply -nomcp, and allow reading -clientcmdline to override setting the map parameter to 127.0.0.1 by default
	Fix RunProjectCommand to remove ios-specific checks to not pass weird platform parameters, and instead never pass them
	Fix PS4Platform to pass along command line when calling build cook run, args needs to be the last parameter so explicitly set -target=

Change 3390859 on 2017/04/12 by Mike.Beach

	T3D class fields now export with the class's fully qualified path name (to avoid abiguity). Since we can have multiple classes with the same name (Blueprints in different folders), we have to use the class's fully qualified object path.

	#jira UE-28048

Change 3390914 on 2017/04/12 by Lukasz.Furman

	fixed missing navlink component's transform in exported navigation data
	#jira  UE-43688

Change 3391122 on 2017/04/12 by Ben.Zeigler

	Add new PreloadPrimaryAssets call to AssetManager that stream the desired assets without modifying the official load/unload state. This is useful if you want to preload things in case the might be used in the future, and it also supports recursion
	Fix crash calling GetAssetDataForPath with null path

Change 3391494 on 2017/04/12 by Dan.Oconnor

	Fix bad references in deep object (widget) hierarchies

	#jira UE-43802

Change 3391529 on 2017/04/12 by Dan.Oconnor

	Fix log spam, accidently submitted

	#rnx

Change 3391756 on 2017/04/12 by Dan.Oconnor

	LinkExternalDependencies needs to be performed before we RefreshVariables

	#jira UE-43843

Change 3392542 on 2017/04/13 by Marc.Audy

	Ensure that initialized actors get cleaned up when removed from world even if that world hasn't begun play.
	#jira UE-43879

Change 3392746 on 2017/04/13 by Marc.Audy

	(4.16) When duplicating a blueprint node, correctly make the new node a sibling of the duplicated node, not a child of it (unless duplicating the root component).
	Also resets scale of a duplicated root component to 1 to avoid a squaring of the scale for that component.
	#jira UE-40218
	#jira UE-42086

Change 3393253 on 2017/04/13 by Dan.Oconnor

	Make sure calculated meta data is correctly set on functions generated by the compilation manager (SKEL_ class functions)

	#jira UE-43883

Change 3393509 on 2017/04/13 by Mike.Beach

	Removing hack'ish ResetLoaders() call that was causing undesired side-effects (resetting of a loaded package that other objects were relying on). This was originally intended to release file handles so separate editor processes could make updates and save the file (from CL 1712376). Using ResetLoaders() for this is bad though, as it has too many side effects. Instead we have to wait for GC to run. This also makes sure that GC should run as intended as the CookOnTheFly sever is idling.

	#jira UE-37284

Change 3394350 on 2017/04/14 by Michael.Noland

	Core: Making FDateTime and FTimespan actually reflected, so they get duplicated properly in CopyPropertiesForUnrelatedObjects, etc...
	#jira UE-39921

Change 3395985 on 2017/04/17 by Phillip.Kavan

	#jira UE-38280 - Fix invalid custom type selections on member fields in the User-Defined Structure Editor after a reload.

	Change summary:
	- Ensure that the 'SubCategoryObject' member in a UDS variable descriptor has been loaded when converting to an FEdGraphPinType.

Change 3396152 on 2017/04/17 by Marc.Audy

	TickableGameObjects that have IsTickableInEditor false should not tick in the editor
	#jira UE-40421

Change 3396279 on 2017/04/17 by Phillip.Kavan

	#jira UE-43968 - Fix failed validation of bitmask enum types when serializing bitmask literal nodes.

Change 3396299 on 2017/04/17 by Dan.Oconnor

	Fix resintancing issues exposed by running TM-Gameplay with -game. We cannot reinstance actors in levels on load because the scene is not created.

	#jira UE-43859

Change 3396712 on 2017/04/17 by Marc.Audy

	Call PostLoad on subobjects before copying for unrelated properties to avoid cases where an out of date object patched over in the linker has not been brought up to date
	#jira UE-38234

Change 3396718 on 2017/04/17 by Mike.Beach

	Adding a search bar to the components tree for Blueprints.

	#epicfriday
	#jira UE-17620

Change 3396999 on 2017/04/17 by Mike.Beach

	In generated code, call event '_Implementation' functions directly for interface functions being invoked on self (avoids a UHT runtime error).

	#jira UE-44018

	Definition pieces of BlueprintInternalUseOnly to fix UHT errors with structs already marked to use it

Change 3397912 on 2017/04/18 by Mike.Beach

	Fix for CIS warnings about shadowed variables (fallout from CL 3396718).

Change 3398455 on 2017/04/18 by Marc.Audy

	Make less critical errors log an error rather than immediately throwing allowing multiple errors to be reported in the same compile

Change 3398491 on 2017/04/18 by Marc.Audy

	BPRW/BPRO in a non-BlueprintType is now a UHT error

Change 3398539 on 2017/04/18 by Marc.Audy

Change 3399412 on 2017/04/19 by Marc.Audy

	Fix Match3 blueprint type struct markups

Change 3399509 on 2017/04/19 by Phillip.Kavan

	#jira UE-38574 - Fix AnimBlueprint function graphs marked as 'const' to treat 'self' as read-only when compiling.

	Change summary:
	- Modified FKismetCompilerContext::ProcessOneFunctionGraph() to use the function graph schema rather than the compiler context schema for both the function context's schema as well as testing the function for 'const'-ness. For AnimBPs, the compiler context and the function graph context can differ, so we need to make sure we are using the right one when making queries for a specific function context during compilation.
	- Minor cleanup: changed the function context schema to be 'const' in order to be consistent with the function graph GetSchema() API's result. Added a few 'const' qualifiers where needed to match.
	- Added a new object version in order to avoid breaking compilation of existing AnimBP function graphs that may already be violating the 'const' rule (this is the same thing that was done when 'const' was first added to "normal" BP function graphs). Just as with normal function graphs in place before the addition, a warning will be generated for existing AnimBP function graphs if they violate 'const' correctness, and an error will be generated for all new ones.

Change 3399749 on 2017/04/19 by Mike.Beach

	Hiding the Nativized Blueprints plugin from the in-editor browser (prevent users from disabling it).

Change 3399774 on 2017/04/19 by Marc.Audy

	ConditionalPostLoad is already called on StaticMesh earlier in the function

	#rnx

Change 3400313 on 2017/04/19 by Mike.Beach

	Mirroring CL 3398673 from 4.16

	Now, with ICWYU, making sure that the coresponding header gets included first in nativized Blueprint files (else we get a UHT error). Had to fixup some ShooterGame specific files as a result (they had missing includes and forward declarations).

	#jira UE-44124

Change 3400328 on 2017/04/19 by Mike.Beach

	Missing file from mirrored change (CL 3400313 - mirroring CL 3398673 from 4.16)

	#jira UE-44124

Change 3400415 on 2017/04/19 by Chad.Garyet

	adding physx switch build to framework

Change 3400514 on 2017/04/19 by Mike.Beach

	Back out changelist 3400313 / 3400328 (mirrored from CL 3398673 in 4.16), as it was producing "include PCH first" errors. Likely, CL 3398673 was a fix for a 4.16 specific change, altering the expected include order. We'll have to wait for this one to be integrated back.

Change 3400552 on 2017/04/19 by Marc.Audy

	Undo the calling of post load prior to the CPFUO as dependent objects may not yet be loaded. Instead copy the need load flag to the new CDO subobject, similarly to how the top level CDO object copies its flags over.
	#jira UE-44150

Change 3400815 on 2017/04/19 by Marc.Audy

	Spelling fix (part of PR #3490)

	#rnx

Change 3400918 on 2017/04/19 by Marc.Audy

	Partial pull of PR #3490: Improved remapping game controls support (Contributed by projectgheist)
	This portion brings in the exposure of the bindings to blueprint
	#jira UE-44122

	fix kitedemo blueprint type markup

	#rnx

Change 3401702 on 2017/04/20 by Mike.Beach

	Make it so plugins added to a project through the .uproject's 'AdditionalPluginDirectories' list get folded into the generated code project (for visual studio, etc.).

Change 3401720 on 2017/04/20 by Mike.Beach

	Add white and black lists for target type (game, client, server, etc.) to plugin module descriptors.

Change 3401725 on 2017/04/20 by Mike.Beach

	Whitelisting the nativized Blueprint plugin for only the targets it was built for (game, server, or client).

Change 3401800 on 2017/04/20 by Ben.Zeigler

	Add Algo::BinarySearch, LowerBound, and UpperBound. These are setup to allow binary searching a presorted array, and allow for specifying projection and sort predicates. Convert some engine code to use it
	Add TSortedMap, which is a map data structure that has the same API as TMap, but is backed by a sorted array. It uses half the memory and performance is faster below n=10
	Add FName::CompareIndexes so a SortedMap with FNames can be used without doing very slow string compares, and FNameSortIndexes predicate to sort by it
	Add code to Algo and Container tests. Split up container tests so the new ones aren't run in smoketest as they are a bit slow
	Add RemoveCurrent and SetToEnd to ArrayIterator

Change 3401849 on 2017/04/20 by Marc.Audy

	Partial pull of PR #3490: Improved remapping game controls support (Contributed by projectgheist)

	Focus the search box when expanding the map value type
	#jira UE-44211

Change 3402251 on 2017/04/20 by Ben.Zeigler

	Fix issue where SortedMap needs to be resorted after serialization, because the sorting may have changed from when it was saved out

Change 3402335 on 2017/04/20 by Ben.Zeigler

	Significant changes to FAssetData serialization and memory, cuts memory significantly but will break code that was using some of the internal API that was not properly hidden before
	Both Editor and Runtime cache now use the same FAssetRegistryVersion, which is now registered as a custom version
	Rename FAssetData and FAssetPackage operator<< to SerializeForCache to make it clear that it isn't safe to use for general serialization
	Remove GroupNames from FAssetData, it has not been useful since the UE4 package structure changed around 4.0
	Rename generic-sounding but not actually generic SharedMapView class to AssetDataTagMapSharedView to indicate what it is actually used for
	Change TagsAndValues to use a new array-backed TSortedMap as the base structure instead of a hash map. Also, it only allocates the map on demand, which saves significant memory at runtime as many packages have no tags
	Add bFilterAssetDataWithNoTags to [AssetRegistry] ini section, if set it will only save cooked asset data if it has tags, off by default but saves significant memory if your whitelist is set up properly
	Fix issue where asset registry tags updated by loading assets during cook were not being reflected in the cooked registry
	Add AssetRegistry::GetAllocatedSize and add to MemReport output

Change 3402457 on 2017/04/20 by Ben.Zeigler

	Enable asset registry iteration and stripping unused asset data in Fortnite. Registry iteration is already on in //Fortnite/Main, stripping is a new feature I want to test

Change 3402498 on 2017/04/20 by Ben.Zeigler

	CIS fix. Why did this compile locally?

Change 3402537 on 2017/04/20 by Ben.Zeigler

	Remove ensure for making AssetData for subobjects, the editor does this for thumbnail creation in some cases

Change 3402600 on 2017/04/20 by Ben.Zeigler

	Add bShouldGuessTypeAndNameInEditor to manager settings, can be set false for games where type cannot be safely implied and content must be resaved
	Fix up some bool setting code inside asset manager, and fix const correctness and for iterator issues
	AssetManager can now discover any BlueprintCore type when bHasBlueprintClasses=true
	Add AssetManager.DumpAssetRegistryInfo to output detailed asset registry usage stats
	Add Primary Name to asset audit window by default

Change 3404463 on 2017/04/21 by Ben.Zeigler

	Fix asset data code to not ensure when loading an object with invalid exports, and instead print warning with name of package that needs to be resaved
	Resave a map that had a redirector from a DIFFERENT package saved in it's exports. I do not understand how this happened, but it appears to be related to the lightmap BuiltData transition when old maps are opened

Change 3404465 on 2017/04/21 by Ben.Zeigler

	Fix issue with trying to load editor-only asset classes in a cooked build
	Fix issues with renaming or changing template Ids of assets from the editor
	Always print the Duplicate Asset ID error, as if you have more than one the ensuremsg only goes off once

Change 3404481 on 2017/04/21 by Dan.Oconnor

	#jira UE-44213 - Nativizing a Blueprint class with a non-nativized Blueprint class subobject dependency will no longer lead to a crash at load time.

	Change summary:
	- Modified the FFakeImportTableHelper ctor to inject subobject CDOs into the 'SerializeBeforeCreateCDODependencies' array. This in turn ensures that EDL will serialize those subobject CDOs (if necessary) before we create the subobject's nativized owner's CDO at load time.
	- Modified FEmitDefaultValueHelper::GenerateCustomDynamicClassInitialization() to emit MiscConvertedSubobject instantiations AFTER we emit the FillUsedAssetsInDynamicClass() call. This is now consistent with the code emitted for other subobjects (all of which assumes that the UsedAssets array has been initialized).
	- Modified FFindAssetsToInclude::HandleObjectReference() to add UField owner CDOs in addition to the owner class to the asset dependency list. This ensures that owner CDOs will be emitted alongside the class to both the nativized asset dependency table as well as to the fake import table associated with the UDynamicClass linker for the nativized BP asset.

Change 3416425 on 2017/05/01 by Phillip.Kavan

	#jira UE-44219 - Nativizing a Blueprint class with a nativized DOBP class dependency will no longer lead to a compile error at cook/nativization time.

	- Modified the FGatherConvertedClassDependencies ctor to properly handle DOBPs in exclusive mode that have been explicitly enabled for nativization. Previously, this code wasn't taking that possibility into account, and as a result could lead to a missing header file in a dependent nativized class body's include set.
	- Modified FGatherConvertedClassDependencies::GetFirstNativeOrConvertedClass() to remove the 'bExcludeBPDataOnly' parameter, as it was primarily just being used for a redundant exclusion check when called from the FGatherConvertedClassDependencies ctor. That call site has now been modified to start searching from the super class instead. Additionally, any DOBPs will already fail the preceding WillClassBeConverted() check if they have not been explicitly enabled for nativization in exclusive mode, and will always fail if nativizing in inclusive mode. The extra check was breaking the explicitly-enabled case, so it was removed to allow explicitly-enabled DOBPs to pass.

	Notes:
	- Allowing for explicitly-enabled DOBPs in exclusive mode may be removed in a future change, but since it is currently supported, the changes noted above will at least ensure that the generated code will compile properly for now.

	Fix BP compile errors caused by local variables with invalid default values. There's no reason to set autogenerated here because the nodes are transient and invisible in the UI.
	There is still a problem here, local variables are not getting their default values validated when type is changed, so you end up with an integer that has the default value of a struct.

	#jira UE-44534 Fix it so animation node pins get properly created autogenerated default values that are based on the node struct defaults. This fixes issues when they are reset to other defaults
	#jira UE-44532 Fix it so connecting an animation asset pin on a node player resets the pin value to the autogenerated default instead of the cached asset. This was causing old unused assets to get unnecessarily cooked
	Fix it so any animation node with an exposed pin that is an object property will reset that object propery when the pin is exposed. This fixes UE-31015 in a generic way
	Change the OptionalPinManager to take a Defaults address as well as a current address, to allow setting autogenerated defaults properly
	Remove Import/ExportKismetDefaultValueToProperty as they were redundant with PropertyValueFromString and were using the wrong pin setting functions, replaced with PropertyValueFromString_Direct and calling the schema pin set functions

	Change it so the asset registry reads in a list of all scanned redirectors and adds them to GRedirectCollector, this means that saving a string asset reference will automatically fix it up to point to the redirector destination
	Change the default behavior of FAssetPtr serialize on ArchiveUObject to match what most of it's children want, and remove several special case hacks. It now serializes as asset reference when saving/loading, and as object for other cases

	Removed some hacky bits in Core that only existed to support FixupRedirects
	Change it so the AssetRegistry listens to DirectoryWatcher callbacks in commandlets now that commandlets use the asset registry properly. This won't do anything unless you tick directory watcher the way that ResavePackages does

	- Modified IBlueprintCompilerCppBackend::GenerateCodeFromStruct() to include an output parameter for CPP source and modified FBlueprintCompilerCppBackendBase to match the updated API.
	- Modified FBlueprintNativeCodeGenUtils::GenerateCppCode() to adjust the call to GenerateCppCodeForStruct() to include CPP source output.
	- Modified FGatherConvertedClassDependencies::DependenciesForHeader() to switch UDS property dependencies to be forward declarations rather than includes (for default value init code).
	- Modified FEmitDefaultValueHelper::GenerateGetDefaultValue() to emit implementation details to the 'Body' container, and adjust the header content to be a declaration only.
	- Modified FIncludeHeaderHelper::EmitInner() to exclude a potentially-redundant line for the module's .h file, for the case when the caller has included the base filename in the 'AlreadyIncluded' set.
	- Modified FEmitterLocalContext::FindGloballyMappedObject() to limit the 'TryUsedAssetsList' path to UClass conversions only (since that requires a UDynamicClass target to work).
	- Modified FGatherConvertedClassDependencies::DependenciesForHeader() to only include BPGC fields if they are also being converted. Eliminates an issue with missing header files in generated code.

Change 3426906 on 2017/05/05 by Ben.Zeigler

	#jira UE-11189 Fix function/macro input default values to show as a pin customization instead of as a broken text box that doesn't work correctly for most types. This fixes enums and provide validation for other types
	Types that don't have a customization (most structs) will now show any more, they did not work before either
	#jira UE-21754 Hide function default values if pass by reference is set
	Fix it so changing input parameter will also reset default value, to avoid having the wrong type value set and to work the same as local variables

Change 3426941 on 2017/05/05 by Dan.Oconnor

	Fix determinstic cooking of LoadAssetClass nodes in macros

Change 3427021 on 2017/05/05 by Dan.Oconnor

Change 3427135 on 2017/05/05 by Phillip.Kavan

	#jira UE-44702 - Restore code-based interface classes to Blueprint editor UI.

	Change summary:
	- Partially backed out CL# 3348513 to return to previous behavior for 4.16. The UI is no longer filtering on the __is_abstract() type trait for interface classes.
	- Modified FNativeClassHeaderGenerator::ExportClassFromSourceFileInner() to emit the _getUObject() declaration for native interface types as a default implementation that returns NULL rather than as a pure virtual declaration.

	#rnx

Change 3427144 on 2017/05/06 by Marc.Audy

	Fix init order

	#rnx

Change 3427146 on 2017/05/06 by Marc.Audy

	remove stray semicolon

Change 3427242 on 2017/05/06 by Phillip.Kavan

	#jira UE-44744 - Fix a regression in which a UMG Widget Blueprint property not explicitly marked as a variable would cause Blueprint nativization to fail at package time.

	Change summary:
	- Modified FWidgetBlueprintCompiler::CreateClassVariablesFromBlueprint() to only add 'Category' metadata when we set the 'CPF_BlueprintVisible' flag on the UProperty, which in is now tied to whether or not the property has been explcitly marked as a variable. This avoids a UHT warning when compiling the nativized codegen that would cause packaging to fail.

	Avoid node reconstruction when we're compiling a blueprint with no linker (e.g., a duplicated blueprint)

	#jira UE-44777

Change 3428599 on 2017/05/08 by Ben.Zeigler

	CIS fix.

	#rnx

Change 3429583 on 2017/05/08 by Ben.Zeigler

	Fix SGraphPinClass to work properly after my changes to allow unloaded assets. For Class pins we need to store separate Runtime and Editor asset data objects, as one has _C and refers to the class, and the other doesn't and refers to the blueprint. The content browser wants the editor path, the pin defaults want the runtime path.
	Change default value widgets to look more like properties widgets by forcing them to act as highlighted and disabling black background

Change 3429640 on 2017/05/08 by Marc.Audy

	Fix issues with select nodes in macros connected to wildcard pins.
	#jira UE-44799

	Disable defaults UI for object/class/interface hard references as it is disabled in KismetCompiler

Change 3429947 on 2017/05/08 by Michael.Noland

	Core: Backing out CL# 3394352 (marking FDateTime and FTimespan nonexport member Tick with UPROPERTY()), which will re-break UE-39921 but fix UE-44418
	There appears to be a more serious underlying issue with how the CDO is instanced which needs to be addressed
	#jira UE-44418

	#reimplementing 3411681 from Release 4.16

Change 3429987 on 2017/05/08 by Ben.Zeigler

	#jira UE-44798 Do a better job of validating object paths saved as default values, due to an old bug with local variables some object paths are saved as struct exportext
	At load time clear invalid default value for local variables
	Add IsValidObjectPath to FPackageName that validates the passed in path would be valid to load with LoadObject
