Rust 1.100 drops host-tool support for 32-bit Windows targets

blog.rust-lang.org by Mateusz Mikuła, Ralf Jung Editor score 7/10

Rust will continue distributing standard libraries for i686 Windows, but compiler and other host tools will no longer be available for those targets. Teams building 32-bit Windows binaries will need to cross-compile from a supported host.

What

Rust 1.100 demotes i686 Windows targets so they no longer provide host tools such as the compiler.

How

The standard library will remain available, and developers can build 32-bit Windows binaries by cross-compiling from a supported host toolchain.

Why it matters

Engineers maintaining 32-bit Windows builds will need a supported host environment; other 32-bit platforms are unaffected.
