The Rust Programming Language Blog: Announcing Rust 1.45.2 |
The Rust team is announcing a new version of Rust, 1.45.2. 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, getting Rust 1.45.2 is as easy as:
rustup update stable
If 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
1.45.2 on GitHub.
1.45.2 contains two fixes, one to 1.45.1 and the other to 1.45.0.
#[track_caller]
on trait objectsTrait objects with methods annotated with #[track_caller]
would be
miscompiled. #[track_caller]
is not yet stable on 1.45. However, the standard
library makes use of this on some traits for better error messages. Trait
objects of SliceIndex
, Index
, and IndexMut
were affected by this bug.
..
to an identifierIn 1.45.1, we backported a fix for #74539, but this fix turned out to be incorrect, causing other unrelated breakage. As such, this release reverts that fix.
Many people came together to create Rust 1.45.2. We couldn't have done it without all of you. Thanks!
