New features

GLES, GLAPI and OpenGL ES support;
Enable OpenMP.

Known issues

If you used per-app deployment to deploy Mesa3D desktop OpenGL driver you may encounter an error mentioning libglapi.dll. To fix it just do a re-deploy of the desktop OpenGL driver. If you don't remember if an affected program is 32-bit or 64-bit, right click on opengl32.dll shortcut in the folder where the program executable is located and select open file location. If the location ends in x64 then it's 64-bit otherwise it's 32-bit;
osmesa does not have GLES support, also its integration with softpipe, llvmpipe and swr may be broken. This is due to workaround for Mesa bug 106843 which affects Mesa3D builds with GLES support since at least 2012.

Deployment utility

Made easy to swap osmesa variants.
Check before attempting to create symbolic links. Avoid harmless errors which may be confusing.

Build script

Drop S3TC build if Mesa master source code is detected. S3TC is now built-in. Texture cache enabling patch is still needed though.
Python packages updating: use both pip install -U explicitly and pip freeze in a hybrid approach for most optimal behavior.
Improved PATH cleanning.
Support building S3TC with MSYS2 Mingw-W64 GCC by default. They fixed their problem with 32-bit binaries when they upgraded to GCC 7.2.0 (Alexpux/MINGW-packages#2271).
Drop suport for Visual Studio 2015 completely. It survived so long due to Scons 3.0.0 issues.
Mesa build without git workaround: git_sha1.h was generated in an incorrect location during 64-bit builds.
Drop Scons 3.0.0 compatibility patch. It landed in Mesa 17.2.3.

Build script

Fixed python packages update check. Always check if mako not found, ask otherwise.
Made build script aware of Mesa branches, helps with patches applicability narrowing.
Add Scons 3.0.0 compatibility patch to Mesa3D Git-powered auto-patches. Only apply it to Mesa stable, patch is upstream now.
Determine Mesa branch even if it is not built. Preparation for S3TC merger.
Ensure auto-patching is done once and only once.
Look for Git before trying to patch. It is pointless if it is not found.
This script won't find Scons if it isn't in a certain relative location to it. Addressed this by fixing scons locating when Python it's in PATH right from the beginning.
Added Scons to python update checking and auto-install. Depends on wheel. 1 less dependency requiring manual installation.
Halt execution if Mesa is missing and it can't be acquired or its acquiring is refused by user.
Drop LLVM 5.0 compatibility patch. Patch is upstream in all active branches.

There is a compatibility fix for Scons 3.0.0.
Scons can now be acquired by build script automatically. Depends on wheel.
Git version control is now mandatory due to compatibility with latest Scons needing a patch.
Updated questions list asked by this script.

Known issues

Mesa build: Scons 3.0.0 always uses target architecture compiler when using cross-compiling environment. This may impact compilation performance when making 32-bit builds.

17.2.1.500-1

Updated Mesa3D to 17.2.1;
Added OpenSWR support to deployment utility;
Built Mesa3D with LLVM 5.0 using a patch which adds support for it;
Built LLVM with Visual Studio 2017 v15.3.4;
Mesa3D build: updated Python to 2.7.14;
Build script: Always use a compiler that matches host architecture; previously CMake with MsBuild was always using 32-bit compiler throwing a warning in the process; ninja and Scons were using the compiler matching the build target architecture;
Build script: Support downloading Mesa code using Git, apply LLVM 5.0 support and S3TC texture cache enabling patches automatically using Git when possible;
Deployment utility and build script: 32-bit OpenSWR is unsupported;
Build script: Attempted restore of Visual Studio 2015 support; Visual Studio 2015 compatibility toolset for VS2017 should work fine; Visual Studio 2015 default toolset is untested;
Build script documentation: switch Mesa download link to HTTPS, info about LLVM 5.0 support auto-patch, S3TC texture cache auto-patching, unsupported 32-bit OpenSWR and build script wizard updates.

LLVM and Mesa are both built with Visual Studio 2017 v15.0.26403.7.

Enhancement

Added OpenGL and GLSL version override samples (work in progress towards a complete guide).

Notable upstream fix:

LLVM 4.0 support in 2 steps closing bug 100201: a. c11/threads: Include thr/xtimec.h for xtime definition when building with MSVC; b. scons: update for LLVM 4.0.

Notable upstream enhancement:

GL_ARB_gpu_shader_int64 on i965/gen8+, nvc0, radeonsi, softpipe, llvmpipe.

17.0.5.391-1

Updated Mesa to 17.0.5;
Rebuilt LLVM 3.9.1 using Ninja build system. Saves a bit of storage space at my end;
Built everything with Visual Studio 2017 v15.0.26403.7.

17.0.4.391-2

Buildscript improvements:

Be aware of the fact that CMake and Python can add themselves to PATH;
Fixed a serious issue causing the script to produce Debug LLVM builds instead of Release. cmake --build with Visual Studio generators does not honor CMAKE_BUILD_TYPE.
Binaries produced for 17.0.4.391-1 were not affected as LLVM build was manually configured in Visual Studio IDE.

17.0.4.391-1

Various buildscript enhancements and fixes;
Quick deployment enhancements;
Dropped system-wide registration.

Known issue:

In place upgrade from 17.0.3.391-2 and older has been broken due to changes made to installer when system-wide registration was dropped. This won't be fixed. Uninstall old version before installing this one.

17.0.3.391-2

Bugfix

Remove Program group screen from installer didn't actually work.
The portable version is unchanged from previous release.

17.0.3.391-1

Updated Mesa to 17.0.3;
Added Osmesa off-screen rendering driver and graw library;
Applied a patch for S3TC performance boost, credit goes to Federico Dossena;
major build script enhancements (ninja support allowing LLVM build with backward compatibility toolset, LLVM and Mesa toolset matching validation, easy packaging post-build support, multiple bug fixes);
Added support for Osmesa to local deployment utility, ported bug fixes from build script.

17.0.2.391-2

Clarify that path to program launcher is quoted automatically in local deployment utility;
Remove Program group screen from installer, it served no purpose and just caused confusion;
Delete 32-bit cygwin runtime from system32/syswow64 leftover from 17.0.1.391-2 if present.
There are no changes with portable version since 17.0.2.391-1.

17.0.2.391-1

Changes

Updated Mesa to 17.0.2;
Used Visual Studio 2017 to build LLVM, patched LLVM 3.9.1 to build with MSVC 2017 successfully as LLVM 4.0 is not yet supported;
Used Visual Studio 2017 toolset for Mesa build working around Mesa bug 100201;
multiple buildscript and guides enhancements;
unified 32 and 64-bit installers and local deployment utilities respectively.

Known issue

In place upgrade leaves a 32-bit Cygwin runtime in Windows\system32 for 32-bit Windows or Windows\syswow64 for 64-bit Windows if you are upgrading from 17.0.1.391-2. Clean it by downloading and running Cygwin installer for 32-bit Windows.

17.0.1.391-2

Support GL_EXT_texture_compression_st3c;
Use Mingw build of libtxc_dxtn for 64-bit apps and Cywin build of libtxc_dxtn-s2tc for 32-bit apps.
