+Portable Computing Language (PoCL) v3.1 released
+------------------------------------------------
+
+PoCL is a portable open source (MIT-licensed) implementation of the
+OpenCL standard. It likely supports the minimal v3.0 feature set (official
+conformance stamp not yet applied for).
+
+In addition to being an easily portable multi-device (truly
+heterogeneous) open-source OpenCL implementation, a major goal of this
+project is improving interoperability for diversity of OpenCL-capable
+devices by integrating them to a single centrally orchestrated platform.
+Another key goal is to enhance performance portability of OpenCL
+programs across device types utilizing runtime and compiler techniques.
+
+Upstream PoCL currently supports various CPUs, NVIDIA GPUs via libcuda,
+Vulkan-compatible GPUs (experimental) and ASIPs (experimental,
+see: http://openasip.org). It is also known to have multiple (private)
+adaptations in active production use.
+
+Release Highlights
+------------------
+
+* Support for Clang/LLVM 15.0.
+* Major rework of the custom device driver (formerly named Accel, now AlmaIF)
+  with support for more device types implementing AlmaIF
+* All device names used to control the platform setup via POCL_DEVICES are now
+  lowercase (as documented in the user manual)
+* Major rework of the custom device driver (formerly named Accel, now AlmaIF)
+  with support for more device types implementing AlmaIF
+* Much improved SPIR-V support for CPU and CUDA drivers
+* Various improvements to & more steps towards implementing the complete API in
+  the WIP Vulkan driver
+* Basic implementation of cl_khr_command_buffer
+
+Misc. Notes
+-----------
+
+* Please note that there's an official PoCL "maintenance policy" in
+place. This text describes the policy and how you can get your favourite
+project that uses OpenCL to remain regression free in the future PoCL
+releases: http://portablecl.org/docs/html/maintainer-policy.html
+
+* We are still looking for ARM CPU and RISC-V CPU maintainers (and
+any other target of your interest). If you are interested in ensuring
+PoCL stays stable for these processor architectures in the future,
+please contact us.
+
+* The dedicated TTASim driver will be deprecated once the AlmaIF driver
+reaches feature parity with it.
