Release Notes

rust-lang/rust (rust)

v1.94.1

Compare Source

===========================

• Fix std::thread::spawn on wasm32-wasip1-threads
• Remove new methods added to std::os::windows::fs::OpenOptionsExt
  The new methods were unstable, but the trait itself is not sealed and so
  cannot be extended with non-default methods.
• Clippy: fix ICE in match_same_arms
• Cargo: update tar to 0.4.45
  This resolves CVE-2026-33055 and CVE-2026-33056. Users of crates.io are not affected.
  See blog for more details.
