 * Fixed the download stuck problem by introducing a timeout of 1 hour for cache downloads.
 * Fix zstd not working for windows on gnu tar in issues.
 * Allowing users to provide a custom timeout as input for aborting download of a cache segment using an environment variable `SEGMENT_DOWNLOAD_TIMEOUT_MINS`. Default is 60 minutes.
+* Two new actions available for granular control over caches - [restore](restore/action.yml) and [save](save/action.yml)

+### 3.2.0
+- Released the two new actions - [restore](restore/action.yml) and [save](save/action.yml) for granular control on cache
+
+### 3.2.1
+- Update `@actions/cache` on windows to use gnu tar and zstd by default and fallback to bsdtar and zstd if gnu tar is not available. ([issue](https://github.com/actions/cache/issues/984))
+- Added support for fallback to gzip to restore old caches on windows.
+- Added logs for cache version in case of a cache miss.
+
+### 3.2.2
+- Reverted the changes made in 3.2.1 to use gnu tar and zstd by default on windows.
