As scheduled, Microsoft Visual Studio 2013 is no longer officially supported. Please upgrade to at least Visual Studio 2015.
- The following files have been removed:
glslang/include/revision.hglslang/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().
glslangshared objects produced by CMake are nowSONAMEversioned using Semantic Versioning 2.0.0.
