New Wasmtime and Wasmer releases appeared this week for advancing WebAssembly on the desktop.

Version 2.0 of Pyston is now available, the Python implementation originally started by Dropbox that builds on LLVM JIT for offering faster Python performance.

Landing yesterday within the Rust code-base is the initial version of a Cranelift code generator back-end. By leveraging the Cranelift code generator that is developed as part of the Bytecode Alliance for WebAssembly, Rustc with Cranelift can experince much faster debug builds.

Version 0.23 of the Eclipse OpenJ9 Java Virtual Machine was released this week in continuing to focus on being a high performance, open-source JVM.

Git 2.29 is now available with experimental support for using SHA-256 to increase security of code repositories over the possibility of intentional SHA-1 collisions with the current indices.

Should you want to use the Ada programming language for GPU programming, the GCC compiler has been working on CUDA support within its front-end for this safety and security minded language.

OpenBLAS 0.3.11 is out as the newest major feature release for this BLAS linear algebra library. While the version number may not make it seem like a big update, it is especially when it comes to new CPU support.

OpenCV as the widely-used, real-time computer vision library is out this week with version 4.5 as a big feature release.

Git 2.29 is on the way with today marking the availability of the initial release candidate.

Python 3.9 is out today as the newest feature update to this extremely popular language in open-source crowds.

SHADERed as the open-source, cross-platform shader integrated development environment now has a compute shader debugger built-in.

The first release candidate of TVM 0.7, the Apache incubator project providing a deep learning compiler stack, is now available.

The first release candidate of the big PHP 8.0 is now available for testing.

Earlier this year Apple engineers announced Swift System as their new library for low-level system interfaces. They have now open-sourced Swift System while also introducing Linux support.

Oracle's GraalVM has seen language support well outside of Java/OpenJDK from Ruby to WebAssembly to R and Python. The newest language seeing an experimental implementation built atop GraalVM is PHP.

RenderDoc 1.10 was released on Friday for this leading open-source program supporting frame-capture-based debugging on Vulkan, OpenGL / GLES, and Direct3D across Windows, Linux, and Android along with platforms like Stadia and the Nintendo Switch.

Compression expert Rich Geldreich who previously worked for the likes of Valve and Unity prior to co-founding his own consulting firm has now made the Crunch and LZHAM technologies available under the public domain.

Lukas Larsson of Erlang Solutions is proposing "BeamAsm" as a JIT compiler for the Erlang virtual machine.

The Wasmer 1.0 alpha release is now available for running WebAssembly programs anywhere. Wasmer is about providing a universal runtime for WebAssembly (WASM) that can run across platforms / operating systems and also embed into other programming languages. Wasmer leverages WebAssembly principles to provide safety around untrusted code on top of its other design features.

Version 5.6 of KDevelop as the KDE-focused integrated development environment is now available.

On Saturday the ISO/IEC 14882:2020 standards draft was approved as the latest major update to the C++ programming language.

Dbus-Broker as the high performance, D-Bus compatible implementation with BUS1 not panning out yet for high-performance, in-kernel IPC has seen a new release.

SHADERed has been available for a while now as a cross-platform, open-source shader editor and for debugging and writing of graphics shaders. SHADERed not only runs on Linux and Windows now but through any modern web browser as of the new v1.4 release.

Vladimir Makarov of Red Hat spoke at this week's Linux Plumbers Conference during the GNU Tools Track on lightweight JIT compilers and the effectiveness (or not) of GCC's JIT implementation as well as LLVM's JIT in the context of just-in-time support for Ruby. But following those shortcomings with GCC/LLVM JIT, he's been working on MIR as a lightweight JIT compiler.

The hipSYCL effort has been about supporting the Khronos SYCL single-source language built on C++ across any CPU with OpenMP as well as AMD Radeon GPUs via ROCm and NVIDIA GPUs via CUDA. The hipSYCL effort has a new "Lite" experimental runtime under development.

Oracle engineers have released a new version of GraalVM, their Java virtual machine that supports JIT compilation, ahead-of-time compilation with GraalVM Native Image, an LLVM runtime, JavaScript runtime, and other language support like Python and R.

Given the uncertainty created by Mozilla laying off roughly a quarter of their staff last week that did include some Rust developers and in looking to further along the Rust ecosystem in its own right, the Rust core developers in cooperation with Mozilla are working to form the Rust Foundation.

TensorFlow Lite for AI inference on mobile devices now has support for making use of OpenCL on Android devices. In doing so, the TFLite performance presents around a 2x speed-up over the existing OpenGL back-end.

SQLite 3.33 is out as the latest update to this widely-used, embed-friendly database library used by countless applications and other software.

Picolibc is a newer C library implementation written by longtime free software developer Keith Packard with a focus on being lightweight for embedded systems. Last year marked the release of Picolibc 1.0 while work on it hasn't let up.
