### Patches
- Simplified MSYS2 compatibility patch;
- MSYS2 patch: Do not create .orig backups.
### Build script
- Restricted LLVM 9, MSYS2 and Python 3 compatibility patches to Mesa 19.2.0/19.1.7 and below as they landed upstream;
- Mesa3D build: Mention patch that is applied;
- LLVM build: Include coroutines component in order to enable compute shaders in Mesa3D llvmpipe driver on Mesa 19.3;
- Mesa3D: Prepared for Scons build with Python 3;
- Do not require CMake if LLVM is prebuilt as this causes the display of a misleading warning;
- Mesa3D: Automatically build without LLVM if LLVM is missing. The appropriate warning is displayed close enough so this may look like warning spam to certain users;
- LLVM: Build LLVMAggressiveInstCombine library as it is needed by coroutines component introduced to enable compute shaders. This also needs this [upstream cntribution](https://gitlab.freedesktop.org/mesa/mesa/merge_requests/2215) in order to be effective.
# 19.2.0
- Updated Mesa3D to [19.2.0](https://www.mesa3d.org/relnotes/19.2.0.html).

# 19.1.7
- Updated Mesa3D to [19.1.7](https://www.mesa3d.org/relnotes/19.1.7.html).
### Build script
- LLVM build: Clean up component names used to call llvm-config with. Tests done with llvm-config indicate that only engine and irreader component names are needed to get the list of all necessary libraries for Mesa3D build, everything else being superfluous. This cleanup also made build script ready for LLVM 9;
- LLVM build: Exclude LLVMAggressiveInstCombine from build as it's not used by Mesa3D;
- Also add Python Scripts folder to PATH in addition to Pyhon root folder just to be safe and to match what Mesa3D official AppVeyor CI does.
### Debug
- LLVM needed libraries dumper can now work with or without those libraries being present. If some libraries are present only missing libraries names are dumped.
### Upstream contribution

### 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](https://bugs.freedesktop.org/show_bug.cgi?id=106843) which affects Mesa3D builds with GLES support since at least [2012](https://lists.freedesktop.org/archives/mesa-users/2012-May/000431.html).
### End-user guide
- Document an issue with Virtualbox VMs that may happen if Mesa3D desktop OpenGL driver is installed inside the VM using system-wide deployment tool;

# 17.3.0.500-1
-  Updated Mesa3D to [17.3.0](https://www.mesa3d.org/relnotes/17.3.0.html).

This is the first release of Mesa3D with built-in S3TC support so there is no dxtn.dll anymore. I enabled S3TC texture cache as always as integration made no change on that front. See [Mesa3D release notes](https://www.mesa3d.org/relnotes/17.3.0.html) for details.
 
- LLVM and Mesa3D were built with Visual Studio 2017 v15.5.1.
### Build script
- Use a simple python script to update all python packages. Don't load python scripts in PATH. Things might work fine regardless.
### Build script documentation
- Update Visual Studio 2017 list of components needed to build Mesa and LLVM.
### Usage documentation
- OpenGL 4.6 context handling landed in Mesa 17.3.
# 17.2.6.500-1
- Updated Mesa to [17.2.6](https://www.mesa3d.org/relnotes/17.2.6.html).
- Built with Visual Studio 2017 v15.4.4 and Scons 3.0.1.
### Build script
- Python packages update: pip freeze is seriously broken. Always use pip install -U. setuptools wasn't updated at all due to pip freeze shortcomings. Also Scons 3.0.1 wasn't picked up despite being live on Pypi.
- Python packages: wheel is no longer needed.
### Build script documentation
- Workaround a pywin32 installer bug.
- Updating setuptools pre-loaded with Python allows for successful installation of Scons via Pypi without having to install wheel.
# 17.2.5.500-1
- Updated Mesa3D to [17.2.5](https://www.mesa3d.org/relnotes/17.2.5.html).

# 17.2.4.500-1
- Updated Mesa3D to [17.2.4](https://www.mesa3d.org/relnotes/17.2.4.html).
- Built LLVM and Mesa3D with Visual Studio 2017 v15.4.1.
- Built S3TC with Mingw-w64 standalone GCC 7.2.0.
### Build script
- Fix Mesa version detection logic epic fail with release candidates.
- Dead variables clean-up.
- Load Visual Studio environment only when building LLVM with Ninja.
- S3TC build: If both MSYS2 and standalone Mingw-W64 are installed let the user pick which to use.
- S3TC MSYS2 build: prefer 64-bit MSYS2 over 32-bit if both installed.
### Build script documentation
- S3TC build with standalone Mingw-w64 is no longer deprecated. GCC 7.2 update finally took place.
- You are now asked which flavor of Mingw-W64 to use when building S3TC if both MSYS2 and standalone are installed.
# 17.2.3.500-1
- Updated Mesa3D to 17.2.3.
- Built S3TC with MSYS2 Mingw-w64 GCC 7.2.0.
- Built LLVM 5.0 and Mesa with Visual Studio 2017 v15.4.0.
### 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 <package-name> 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.
- Allow building Mesa without git since Scons 3.0.0 compatibility patch landed in Mesa stable.
### Build script documentation
- MSYS2 Mingw-w64 is now the preferred method to build S3TC.
- 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.

- 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](https://bugs.freedesktop.org/show_bug.cgi?id=102564#c5);
- 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](https://bugs.freedesktop.org/show_bug.cgi?id=102564#c5) and build script wizard updates.
