 ## What's New
 ### v3
+* Added support for caching from GHES 3.5.
+* Fixed download issue for files > 2GB during restore.
 * Updated the minimum runner version support from node 12 -> node 16.
+* Fixed avoiding empty cache save when no files are available for caching.
+* Fixed tar creation error while trying to create tar with path as `~/` home folder on `ubuntu-latest`.
 
-### v2
-* Increased the cache size limit to 10 GB.
-* Added support for multiple paths, [glob patterns](https://github.com/actions/toolkit/tree/main/packages/glob), and single file caches.
-
-```yaml
-- name: Cache multiple paths
-  uses: actions/cache@v3
-  with:
-    path: |
-      ~/cache
-      !~/cache/exclude
-    key: ${{ runner.os }}-${{ hashFiles('**/lockfiles') }}
-```
-
-* Increased performance and improved cache sizes using `zstd` compression for Linux and macOS runners
-* Allowed caching for all events with a ref. See [events that trigger workflow](https://help.github.com/en/actions/reference/events-that-trigger-workflows) for info on which events do not have a `GITHUB_REF`
-* Released the [`@actions/cache`](https://github.com/actions/toolkit/tree/main/packages/cache) npm package to allow other actions to utilize caching
-* Added a best-effort cleanup step to delete the archive after extraction to reduce storage space

-## Known limitation
 
-- `action/cache` is currently not supported on GitHub Enterprise Server. <https://github.com/github/roadmap/issues/273> is tracking this.
+## Cache Version
+Cache version is unique for a combination of compression tool used for compression of cache (Gzip, Zstd, etc based on runner OS) and the path of directories being cached. If two caches have different versions, they are identified as unique cache entries. This also means that a cache created on `windows-latest` runner can't be restored on `ubuntu-latest` as cache `Version`s are different. 
 
-Since GitHub Enterprise Server uses self-hosted runners, dependencies are typically cached on the runner by whatever dependency management tool is being used (npm, maven, etc.).  This eliminates the need for explicit caching in some scenarios.
+Example: Below example will create 3 unique caches with same keys. Ubuntu and windows runners will use different compression technique and hence create two different caches. And `build-linux` will create two different caches as the `paths` are different.

+For npm, cache files are stored in `~/.npm` on Posix, or `~\AppData\npm-cache` on Windows, but it's possible to use `npm config get cache` to find the path on any platform. See [the npm docs](https://docs.npmjs.com/cli/cache#cache) for more details.
 
 If using `npm config` to retrieve the cache directory, ensure you run [actions/setup-node](https://github.com/actions/setup-node) first to ensure your `npm` version is correct.
 
 >Note: It is not recommended to cache `node_modules`, as it can break across Node versions and won't work with `npm ci`
