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

Change 2731596 on 2015/10/16 by Keith.Judge

	Fast Semantics - Add deferred resource deletion queue to make deleted resources be actually deleted a number of frames later so that the GPU is definitely finished with them. Hooked up the temporary SRVs for dynamic VBs as a first step.

Change 2764244 on 2015/11/12 by Keith.Judge

	Stop creating/deleting SRVs for dynamic buffers all the time. Instead add a new view when a new buffer is cycled and keep them around until the buffer is dead.

Change 2936695 on 2016/04/07 by Mark.Satterthwaite

	Disable Metal on Mac OS X versions prior to 10.11.4 because their drivers are too buggy and lots of issues users will encounter were fixed in 10.11.4.

Change 2936701 on 2016/04/07 by Mark.Satterthwaite

	Re-enable DistanceFieldAO on Mac Metal, but disable the support for Heightfield composition into the DistanceFieldAO as that currently requires Read+Write texture support which isn't present in Metal yet.

Change 2936702 on 2016/04/07 by Mark.Satterthwaite

	Enable capsule shadows on Metal SM5 for Mac Paragon.

Change 2936704 on 2016/04/07 by Mark.Satterthwaite

	Re-add Metal_MacES3_1 entries in RHIDefinition functions - not quite sure how they disappeared...

Change 2936706 on 2016/04/07 by Mark.Satterthwaite

	Fix implementation of BeginRenderingPrePass to only clear the depth+stencil buffers when it is asked to - this fixes LOD fading in Paragon on Mac when parallel execution is enabled. The parallel contexts were being instructed to clear the pre-pass data which was then fouling up all the subsequent rendering.

Change 2936708 on 2016/04/07 by Mark.Satterthwaite

	Extend workaround from 2905206 for UE-27818 to Metal as well as OpenGL - it isn't permissable to have an unbound resource on these APIs as you aren't allowed to make the assumption than an if-branch will protect against null dereference on the GPU.

Change 2936737 on 2016/04/07 by Mark.Satterthwaite

	Changes to reduce Metal's peak memory usage when streaming texture data in when loading levels:
	- When uploading data to Shared memory Metal textures dispose of the source buffer immediately as it won't be required after the call to replaceRegion.
	- Add an optional CVar ("rhi.Metal.MaxOutstandingAsyncTexUploads") and keep a count of outstanding async. texture uploads - really this might be better as a memory count - if teh current outstanding count is greater than the specified CVar wait for all operations to complete before purging the used buffers. By default the CVar is set to 0 which disables the tracking and the game will use all available memory.

Change 2936741 on 2016/04/07 by Mark.Satterthwaite

	For Metal don't use a texture-view unless the mip-range or texture format is different - we only create a texture-view if we absolutely have to in order to avoid performance reductions on some vendors. When this happens we'll have to update the SRV to point to the new source texture but that can be handled on bind.

Change 2936753 on 2016/04/07 by Mark.Satterthwaite

	Mutex the pipeline cache inside each Metal bound-shader-state - with parallel execution this can be modified from multiple threads.

Change 2936758 on 2016/04/07 by Mark.Satterthwaite

	Don't eliminate redundant Metal command-encoders on Intel either - this only seems to work correctly on AMD...

Change 2936762 on 2016/04/07 by Mark.Satterthwaite

	Validate that parallel contexts aren't asked to clear render-targets (incl depth/stencil) as this won't work as desired - each context will end up clearing the contents meaning none of the rendering will propagate which is probably not what you intend.

Change 2936765 on 2016/04/07 by Mark.Satterthwaite

	Fix alignment of blit-commands between textures & buffers in Metal. Mac Metal has no minimum alignment and allows tightly packed rows, but mobile H/W has a fixed row alignment of 64-bytes for linear texture data.

Change 2936767 on 2016/04/07 by Mark.Satterthwaite

	Remove the workaround for old Mac OS X AMD cards not supporting frame-buffer sRGB - I have a feeling it causes more problems than it solves.

Change 2936773 on 2016/04/07 by Mark.Satterthwaite

	Warn the user when trying to run on OpenGL 3.2 GPUs that they are running unsupported and there may be rendering errors and performance problems.

Change 2936777 on 2016/04/07 by Mark.Satterthwaite

	In MetalRHI move the calls that reset the state-cache and command-encoder to EndFrame and fix the fallout. Hopefully this will eliminate the problem where a draw call fails because a call to SetRenderTargets hasn't been made since the last time the command-buffer was submitted.

Change 2936788 on 2016/04/07 by Daniel.Lamb

	PR #2193: Commandlet tweaks: Fixup Redirects and Cook-on-the-fly Server (Contributed by FineRedMist)

Change 2936799 on 2016/04/07 by Mark.Satterthwaite

	Automatically enable RHI thread support in Metal if parallel execution is compiled in unless running the Editor which doesn't support it. The RHI thread is only enabled in Metal when parallel execution is available because there's little to no advantages to the RHI thread with Metal unless parallel execution is enabled. Also only enable async compute support when parallel execution is available and running on an AMD GPU as only AMD support it and again its only really useful when running things in parallel. Disable the async. compute fencing code when async. compute is disabled.

Change 2936923 on 2016/04/07 by Peter.Sauerbrei

	add exception when trying to access an ini section which we don't cache

Change 2937839 on 2016/04/08 by Lee.Clark

	PS4 - BC6H and BC7 support

	#jira OR-14804

Change 2937841 on 2016/04/08 by Lee.Clark

	Fix media player not opening the same file that has just been closed.

Change 2937843 on 2016/04/08 by Lee.Clark

	PS4 - Fix Media player seek and duration

Change 2938272 on 2016/04/08 by Mark.Satterthwaite

	Change the Metal texture lock/unlock code to use the immediate getBytes API to read from the texture unless it is stored in Private memory and requires we use the blit-encoder. This means iOS texture locking won't generally need to use the blit encoder with its row alignment restrictions as all textures will be Shared. On Mac most textures will still be accessed via blit operations  since Private memory is much more common than Managed.

Change 2938471 on 2016/04/08 by Nick.Shin

	load/save with "negative char size value" fixed

	two 'U''s were missing-- causing base64encoder and decoder to not return original data (or expected data for that matter)...

	C++ function shows these signatures:
	    \Engine\Source\Runtime\Engine\Public\SaveGameSystem.h
	    FGenericSaveGameSystem::SaveGame(..., ..., ..., ...<uint8>);
	    FGenericSaveGameSystem::LoadGame(..., ..., ..., ...<uint8>);

	javascript version was using signed operators...

	answerhub 386719 - broken load/save

Change 2938546 on 2016/04/08 by Nick.Shin

	upgrading zlib, openssl, libcurl & libwebsockets
	(part 1, for libwebsockets -- engine changes will be in part 2)

	and writting down all of the build instructions into a single script file

	future tasks may have the script broken to smaller sized files and placed in the respective library folders for simplicity -- for now, it's bundled together to ensure build is all-in-one...

	#jira UEPLAT-1246 - Update libWebsockets
	#jira UEPLAT-1221 - update websocket library
	#jira UEPLAT-1223 - Arrange testing for 'update websocket library'
	#jira UEPLAT-1203 - Add Linux library for libwebsockets
	#jira UEPLAT-1204 - Rebuild libwebsockets with SSL

Change 2939402 on 2016/04/11 by Mark.Satterthwaite

	No need to call synchroniseTexture on iOS when locking a texture for read - that function call is only available and required on OS X.

Change 2940903 on 2016/04/12 by Keith.Judge

	Xbox One - Fix validated driver warning when using async compute with dynamic buffers (remove dynamic buffers).
	Also resurrected the old deferred deletion queue (though simplified the code a lot as TQueue was horrible), as the platform agnostic one can't deal with placement created resources with a separate buffer/resource.
	Moved associated deferred deletion logic out of FD3D11DynamicBuffer.

	Attempted fix for UE-28758, but doesn't actually fix it. :(

Change 2942008 on 2016/04/13 by Keith.Judge

	#jira UE-28758

Change 2942046 on 2016/04/13 by Lee.Clark

Change 2942095 on 2016/04/13 by Mark.Satterthwaite

	MIssed a change to use AlignedStride rather than Stride in FMetalDynamicRHI::RHIReadSurfaceFloatData to fix iOS blit-encoder read-back.

Change 2942383 on 2016/04/13 by Mark.Satterthwaite

	When locking a Metal texture on Mac you have to submit the command buffer & wait in a different location for Private vs. Managed access.

Change 2942419 on 2016/04/13 by Michael.Trepka
