Version history

Current Version

v1.1.4
  • Fixed some regression, and foobillard++ is working fine now
  • Set default GL version to 2.1 (instead of 2.0) for GLES2.0 backend
  • Added ARB_vertex_program and ARB_fragment_program

  • Improved Handling of DXTc textures
  • Improve handling of partially mipmap'd textures
  • Added PYRA Profile
  • Added support for Texture LOD access in Fragment Shaders

  • Added support for program without Vertex Shader
  • Some fixes for program that switch GLX Context frequently.
  • Fixes and improvements in fpe_shaders (less array access)
  • Added support for Clipping Plane in custom shaders (help OpenMW water reflection)
  • Added support for multiple FBO attachement (if hardware support it)
v1.1.2
  • Improved a bit the merger (wich merge subsequent glBegin(...)/glEnd()) efficiency
  • Removed LIBGL_BEGINEND=2 (that was not working correctly, and it complexify the code too much)
  • Added some Direct Access function (from EXT_direct_access)
  • Fixes and Improvements on depth (and depth_Stencil) Texture handling
  • Handling of GL_BGRA color size in VA (for HumandRessourceMachine)
  • Some fixes to fpe_shader (for Neverwinter Night)
  • Rework of Header structure (from @rajdakin)
  • Better test, using "make test" (from @rajdakin, still using apitrace for replay)

  • Numerous optimization and changes in Batch mode.
  • Fixes to GL_BGRA handling
  • Improvement in texture format handling, to limit number of conversions

  • Added VBO when processing glList (only in GLES2+)
  • Added a few more GL3.x functions (like glTexStorage). No real GL3.0 support yet

  • AmigaOS4 support is now live (thanks to @kas1e)
  • Some fixes to texture handling, when uploading (or modifying) a texture in a multi-texture context
  • Small optimization some of the FPE Generated program (many fragment shaders that do texturing)

  • GL4ES has a logo now :) !
  • AmigaOS4 is now fully supported! And SDK (with libs and samples) is available on os4depot

v1.1.0
  • Default backend is now GLES2 (but not on Pandora, still GLES1.1 for compatibility reasons)

  • Various RPi improvements, mainly in the context creation.
  • Various AmigaOS4 improvement and workaround (but still in a beta state)
  • Various improvement in GLX function, with a more accurate way to emulate GLXFBConfig
  • Improved the way eglSurface are created in glx.c, to avoid try to create 2 on the same window (EGL doesn't allow that)
  • Added LIBGL_GLXRECYCLE to not delete eglSurface and recycle them
  • Added tracking of Framebuffers Object and Renderbuffers Objects

  • Added support for Depth Stencil texture when attached to an FBO
  • Added LIBGL_FBO=WxH for all platform
  • Fixed some issue when resized textures attached to an FBO
  • Added LIBGL_NODEPTHTEX to avoid using Depth Texture when available (using renderbuffer can be faster)
  • Added support for Depth Texture when attached to an FBO (if supported by Hardware)
  • Fixes some isue with blitting of FBO when size of Main Framebuffer changed
  • Added option LIBGL_LOGSHADERERROR to get Shader compiler log and error
  • Added support for (emulated) Hardware Instancing
  • Added support for GL_ARB_draw_elements_base_vertex
v1.0.8
  • Fixes and improvments to avoid unnecessary GLES state changes
  • Fixes some memory issues with glBitmap
  • Fixes to FPE (when using multitexture and GL_COMBINE)

  • Optimized glBitmap
  • Added (limited) direct support to GL_UNSIGNED_INT for glDrawElements for hardware that support it
  • Improved (a lot) glBegin/glEnd merger
  • Added Anisotropic filtering support, for hardware that support it.
  • Changed LIBGL_BATCH. It will now try to merge small (parametrable) subsequent glDrawXXXX
  • Changed (simplified) the way texture "0" is handled
  • Improvement to glDrawArrays and glDrawElement, with less copy of data
  • WIP AmigaOS4 support (and BigEndian architecture)
  • Improved NPOT support for "Limited NPOT" hardware
