PoCL 7.1

Highlights

This is mostly a bug-fix/maintenance release.

• Support for LLVM 21 for the CPU and LevelZero devices.
• Support for cl_khr_icd v2.0.0, cl_khr_spirv_queries and SPV_KHR_expect_assume.
• MSVC/Windows build of PoCL with CPU device no longer requires MS Visual Studio Build Tools
  at runtime, MSVC runtime libraries are the only dependency of the CPU driver.

PoCL 7.0

Highlights

• Support for Clang/LLVM 19 & 20
• Support for new Khronos ICD with OpenCL 3.0
• Achieved official OpenCL 3.0 conformance with CPU and LevelZero drivers
• Support for Windows platform with MinGW and MSVC
• Support for input from Julia language via OpenCL.jl package

Full release notes are available here.

Notes about the Windows installers:

• built with Visual Studio 2022 version 17.13
• built with both CPU and LevelZero loadable drivers
• signed only with GPG key (same as git tag), not with Microsoft's tool, therefore upon execution Windows will warn about unverified publisher
• CONF / NOCONF = the ENABLE_CONFORMANCE flag setting of the build
• using the CPU driver requires either installed Visual Studio or VS Build Tools (CLI), because of Clang calling the MSVC linker for the final linking step.

PoCL 7.0 RC 2

Highlights
