First theme: release and platform reliability. The beta work applies security patches for musl and aligns with library fixes for platform behavior. One example is pull request 165637, which makes command status platform specific so targets without real subprocess support, like UEFI, are handled correctly. Another is…
Second theme: clearer compiler errors. Instead of pointing at a whole array type, the compiler now points at the array length when the constant is the wrong kind, in pull request 165516. Next-solver unsize coercion diagnostics get special casing in 165404 so users don't see internal trait details. Related work in…
