• 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.

Bugfix: Remove Program group screen from installer didn't actually work.
The portable version is unchanged from previous release, download it from here.

• 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.

• 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 runtine 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. Get it from here.

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;

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.

• 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.

• Updated to Mesa 17.0.1
• Support in-place upgrade

• Improved installer: clean up registry during uninstallation;
• Added a local deployment utility, quickly deploy mesa for applications incompatible with system-wide installation while saving storage space;
• Updated startup guide.
