 ## [Unreleased]
 
-## [1.5.0] 2022-06-13
+## [1.5.1] 2022-06-24
+
+**N.B** A bug was introduced in v1.5.0/nightly-2022-06-15 which modified formatting. If you happened to run rustfmt over your code with one of those ~10 nightlies it's possible you may have seen formatting changes, and you may see additional changes after this fix since that bug has now been reverted.
+
+### Fixed
+
+- Correct an issue introduced in v1.5.0 where formatting changes were unintentionally introduced in a few cases with a large/long construct in a right hand side position (e.g. a large chain on the RHS of a local/assignment statement)
+- `cargo fmt --version` properly displays the version value again [#5395](https://github.com/rust-lang/rustfmt/issues/5395)
+
+### Changed
+
+- Properly sort imports containing raw identifiers [#3791](https://github.com/rust-lang/rustfmt/issues/3791) (note this is change version gated, and not applied by default)
+
+### Added
+
+- Add new configuration option, `doc_comment_code_block_width`, which allows for setting a shorter width limit to use for formatting code snippets in doc comments [#5384](https://github.com/rust-lang/rustfmt/issues/5384)
+
+### Install/Download Options
