0.10.1 Release Notes
Zig is a general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.
Backed by the Zig Software Foundation, the project is financially sustainable. These core team members work on Zig full-time:

Support Table §
The support table is unchanged. See the 0.10.0 Support Table.
LLVM 15.0.7 §
This release of Zig upgrades to LLVM 15.0.7 which fixed a handful of bugs, including regressions introduced in LLVM 15.0.0. At time of writing, this hyperlink 404s because LLVM project did not provide release notes for this version.
Compiler §
- cmake: move 'continue' statement to avoid cmake bug
- C backend: improve support for non-native float types

- Fixed typo in zig.h causing incorrect behavior.
- LLVM: mangle extern function names for Wasm target
- Fixed detection of MSVC installation on aarch64-windows.

There Are Still Known Bugs Remaining §
Zig has known bugs and even some miscompilations.
Zig is immature. Even with Zig 0.10.1, working on a non-trivial project using Zig will likely require participating in the development process. When Zig reaches 1.0.0, tier 1 support will gain a bug policy.
This is the final planned release in the 0.10.x branch.
