 ## [Unreleased]
 
+## [1.4.2] - 2023-02-15
+
+### Fixed
+
+* Tweak sparse registry version regex to better work with 1.68 nightly versions.
+* Fix command not found issue
+
+## [1.4.1] - 2023-02-13
+
+### Fixed
+
+* Fixed running on macOS #9 #10
+    The macOS images have an ancient version of bash, but the action relies on "newer" features than 2014.
+    We install bash via brew (already pre-installed) to have a new enough version.
+
+    The CI is extended to also run on Windows and macOS to catch such issues earlier in the future.
+
+    Thanks to @GeorgeHahn for reporting the issue.
+
+## [1.4.0] - 2023-02-13
+
+### Changed
+
+* Only set environment variables, if they are not set before.
+    This allows setting environment variables before using this action and keeping their values.
+* Enable stable sparse registry, except on versions 1.66 and 1.67 where this leads to errors.
+
+## [1.3.7] - 2023-01-31
+
+### Fixed
+
+* Disable the stable access to the sparse registry.
+    Setting the value causes problem on version before stabilization, e.g., 1.67.
+    For example, "cargo add" fails.
+
+## [1.3.6] - 2023-01-31
+
+### Fixed
+
+* The the correct environment variable to enable the sparse registry access.
+    The pull request originally had the wrong value, without `CARGO_` prefix.
+
 ## [1.3.5] - 2023-01-21
 
 ### Changed
