 ## [Unreleased]
 
+## [1.5.0] - 2023-05-29

+### Added
+
+* Support installing additional components and targets that are not listed in `rust-toolchain` (#14)
+    Before only the items listed in `rust-toolchain` were installed.
+    Now all the items from the toolchain file are installed and then all the `target`s and `components` that are provided as action inputs.
+    This allows installing extra tools only for CI or simplify testing special targets in CI.
