 # Changelog
 
+## [1.27.1] - 2024-04-14
+
+This new Rustup release involves some minor bug fixes.
+
+The headlines for this release are:
+
+1. Prebuilt Rustup binaries should be working on older macOS versions again.
+2. `rustup-init` will no longer fail when `fish` is installed but `~/.config/fish/conf.d` hasn't been created.
+3. Regressions regarding symlinked `RUSTUP_HOME/(toolchains|downloads|tmp)` have been addressed.
+
+Since the release of 1.27.0, the project has welcomed a total of 7 new contributors.
+Many thanks for your hard work, and we hope to see you again!
+
