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.

Visual Studio 2017 is now required to build LLVM and Mesa3D.

17.2.2.500-1

Updated Mesa3D to 17.2.2.
Built with Scons 3.0.0. Made use of a compatibility patch.
Built LLVM 5.0 and Mesa3D with Visual Studio 2017 v15.3.5.

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.

Build script documentation

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;

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.

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

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
