Rustup 1.27.1: Minor Bug Fixes Can Have a Big Positive Impact

2025/11/08 23:30

The Rustup team is happy to announce the release of Rustup version 1.27.1. Rustup is the recommended tool to install Rust, a programming language that is empowering everyone to build reliable and efficient software.

\ If you have a previous version of Rustup installed, getting Rustup 1.27.1 is as easy as stopping any programs which may be using Rustup (e.g. closing your IDE) and running:

$ rustup self update

\ Rustup will also automatically update itself at the end of a normal toolchain update:

$ rustup update

If you don't have it already, you can get Rustup from the appropriate page on our website.
