  #1295
• Ensure that LoadMemoryCompiledShader returns false upon parse failure.
  #1302

Release 1.11.9 -- 1 Nov 2020 (compared to 1.11.8)

• Build properly against Cuda 11 and OptiX 7.1. #1232
• Windows compile fixes. #1263 #1285
• PugiXML build fixes on some systems. #1262
• Fix asymptomatic potential runtime optimizer bug where certain
  multi-component values were not correctly recognized as nonzero. #1266
• Fix false positive with "debug_uninit" where certain while loops might be
  flagged as using uninitialized values when in fact they were not. #1252
• Slightly optimize by not copying output params to layers that will not be
  used. #1253
• Internals: use the final keyword in certain internal classes where
  applicable. #1260
• Cuda/OptiX back end: Add __CUDADEVRT_INTERNAL__ define to bitcode
  generation, needed to avoid duplicate cudaMalloc symbols with CUDA9+ #1271
• Fix build break against recent OIIO master change where m_mutex field was
  removed from ImageInput. #1281

OSL 1.11.8.0

Release 1.11.8 -- 1 Oct 2020 (compared to 1.11.7)

• Fix broken derivatives of the optional "alpha" return of texture calls
  when the normal color channels return don't have their derivatives used
  but the alpha does. #1258
• Building vs Python: instead of defaulting to searching for python 2.7
  specifically and needing to set PYTHON_VERSION if you want (or have) a
  different one, default to whichever version is found. If multiple versions
  of Python are on the system, you can still use the PYTHON_VERSION cmake
  variable to disambiguate which one you want. #1249
• For the experimental OptiX support, explicitly set the OptiX pipeline
  stack size (fixes some bugs). #1254
• ShadingSystem statistics output (which is printed with testshade --help,
  by the way) now includes information about the SIMD capabilities specified
  at OSL build time, those available at runtime, and the versions of LLVM,
  OIIO, and Imath used. This should help in debugging and issue reporting
  by making it easy to know certain build time choices just by running
  testshade. #1258
