Meson 1.9 released this weekend as the newest feature update to this build system / build automation tool that works well across different software platforms. With Meson 1.9 there is enhanced Rust support, introducing Swift and C++ code interoperability, and other enhancements to this increasingly used alternative to the likes of CMake and Autotools.

With Meson 1.9 there is a new experimental option of "rust_dynamic_std" to allow linking Rust programs so they use a dynamic library for the Rust libstd. On the Rust side Meson now allows Rust and non-Rust sources in the same target.

Meson 1.9 also now supports Swift and C++/Objective-C++ interoperability. Swift executables can be created that link to C++ or Objective-C++ libraries.

Meson 1.9 also introduces a ".flatten()" method to turn nested arrays into a single flat array. There is also clang-tidy integration improvements, support for Qualcomm's ELD embedded linker, various Swift integration additions, and other improvements.
