The Rust team recently released a new version of Rust 1.68.1. 1.68.1 is a bug fix version. The main updates are as follows:

• The Rust 1.68.1 stable release mainly includes changes to the way Rust’s CI builds the Windows MSVC compiler, no longer enabling LTO for Rust code.

  This is currently considered to have no impact on the widespread use of ThinLTO. The Rust compiler uses an unstable flag to enable ThinLTO during compilation.

This release also includes some other fixes:

• repaired with --enable-local-rust Problems building the compiler
• In the linker detection code put $prefix-clang regarded as clang
• Fix a panic in the compiler
