(uses catboostmodel native libraries from the main CatBoost release v1.2.10)

  • Fix prediction of type Probability on CPUs that do not have SSE4 instruction set (that includes all ARM CPUs). Values with probability 0 have been erroneously computed as nan.
  • Fix a race condition in error messages in exceptions in multithreaded programs.
  • [Performance][Windows] __SSE__ compiler flag was not enabled for Windows builds with MSVC compiler. This affected code that relied on this flag including quantization during model inference. It is important to note that the compiler itself was configured for SSE support and could still apply automatic SSE optimizations.
  • [Build] Switch to Conan 2.x. [#2582]
  • [Build] Use 'spawn' instead of 'exec' to avoid issues with maxBuffer overflow.
  • [Build][CUDA] Do not output detailed ptxas statistics by default.
  • [Build][CUDA] Switch from hardcoded gencode specifications in multiple CMakeLists.txt files to the standard CMake variable CMAKE_CUDA_ARCHITECTURES, although the default value is non-standard and specified in cuda.cmake. [#2540]
  • [Build][CUDA] Remove excessive CUDA compilation parallelism that could lead to RAM exhaustion during build. [#3034]
  • [Build][macOS] Support Apple Clang 17. [#2860]
  • [Build][Windows] Support building with MSVC toolsets 14.4*. [#2302]
