+The Rust team has published a new point release of Rust, 1.84.1. 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, getting Rust
+1.84.1 is as easy as:
+
+```
+rustup update stable
+```
+
+If you don't have it already, you can [get `rustup`][rustup] from the
+appropriate page on our website.
