+
+The Rust team has published a new point release of Rust, 1.67.1. 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 1.67.1 with:
+
+```
+rustup update stable
+```
+
+If you don't have it already, you can [get `rustup`][install]
+from the appropriate page on our website, and check out the
+[detailed release notes for 1.67.1][notes] on GitHub.
+

+
+## What's in 1.67.1 stable
+
+Rust 1.67.1 fixes a regression for projects that link to thin archives
+(`.a` files that reference external `.o` objects). The new
+archive writer in 1.67.0 could not read thin archives as inputs, leading to the
+error "Unsupported archive identifier." The compiler now uses LLVM's archive
+writer again, until that format is supported in the new code.
+
+Additionally, the clippy style lint `uninlined_format_args` is temporarily
+downgraded to pedantic -- allowed by default. While the compiler has supported
+this format since Rust 1.58, `rust-analyzer` does not support it yet, so it's
+not necessarily good to use that style everywhere possible.
+
+The final change is a soundness fix in Rust's own bootstrap code. This had no
+known problematic uses, but it did raise an error when bootstrap was compiled
+with 1.67 itself, rather than the prior 1.66 release as usual.
+
+### Contributors to 1.67.1
+
+Many people came together to create Rust 1.67.1. We couldn't have done it
+without all of you. [Thanks!](https://thanks.rust-lang.org/rust/1.67.1/)
