Breaking changes

Visual Studio 2013 is no longer supported

As scheduled, Microsoft Visual Studio 2013 is no longer officially supported. Please upgrade to at least Visual Studio 2015.

10.15.3847 2020-07-20

Breaking changes

• The following files have been removed:
  • glslang/include/revision.h
  • glslang/include/revision.template

The GLSLANG_MINOR_VERSION and GLSLANG_PATCH_LEVEL defines have been removed from the public headers.
Instead each build script now uses the new build_info.py script along with the build_info.h.tmpl and this CHANGES.md file to generate the glslang build-time generated header glslang/build_info.h.

The new public API to obtain the glslang version is glslang::GetVersion().

Other changes

• glslang shared objects produced by CMake are now SONAME versioned using Semantic Versioning 2.0.0.
