The Rust team has published a new point release of Rust, 1.68.1. Rust is a programming language that is empowering everyone to build reliable and efficient software.
If you have a previous version of Rust installed via rustup, you can get 1.68.1 with:
rustup update stableIf you don't have it already, you can get rustup
from the appropriate page on our website, and check out the
detailed release notes for 1.68.1 on GitHub.
Rust 1.68.1 stable primarily contains a change to how Rust's CI builds the Windows MSVC compiler, no longer enabling LTO for the Rust code. This led to a miscompilation that the Rust team is debugging, but in the meantime we're reverting the change to enable LTO.
This is currently believed to have no effect on wider usage of ThinLTO. The Rust compiler used an unstable flag as part of the build process to enable ThinLTO despite compiling to a dylib.
There are a few other regression fixes included in the release:
--enable-local-rust$prefix-clang as clang in linker detection codeMany people came together to create Rust 1.68.1. We couldn't have done it without all of you. Thanks!
