 ## [Unreleased]
 
+## [1.3.4] - 2022-10-15
+
+### Changed
+
+* The last version did not fix all "set-output" commands
+
+## [1.3.3] - 2022-10-13
+
+### Changed
+
+* Switch from set-output to $GITHUB_OUTPUT to avoid warning
+    https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
+
+## [1.3.2] - 2022-09-15
+
+### Fixed
+
+* Fix setting `$CARGO_HOME` to a valid path, in case rustup is installed from the internet.
+    Thanks to @nahsi for providing the fix.
+
+## [1.3.1] - 2022-08-14
+
+### Changed
+
+* Use the sparse-registry on nightly for faster access to the crate registry on nightly.
+    <https://internals.rust-lang.org/t/call-for-testing-cargo-sparse-registry/16862>
+
+## [1.3.0] - 2022-07-30
+
+### Added
+
+* An option to disable configuring Rust cache.
+    Thanks to @filips123 for the PR.
+
+## [1.2.1] - 2022-07-29
+
+### Fixed
+
+* Set environment variables before invoking the cache action.
+    This ensures restoring and saving are using the same cache key.
+
+## [1.2.0] - 2022-07-21
+
+### Added
+
+* Prefer toolchain definitions in `rust-toolchain` or `rust-toolchain.toml` files ([Toolchain File](https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file)).
+    Other input values are ignored if either file is found.
