+
+This repository uses a tool called [Licensed](https://github.com/github/licensed) to verify third party dependencies. You may need to locally install licensed and run `licensed cache` to update the dependency cache if you install or update a production dependency. If licensed cache is unable to determine the dependency, you may need to modify the cache file yourself to put the correct license. You should still verify the dependency, licensed is a tool to help, but is not a substitute for human review of dependencies.

 ## 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.
 
-* Added support for multiple paths, [glob patterns](https://github.com/actions/toolkit/tree/master/packages/glob), and single file caches. 
+Refer [here](https://github.com/actions/cache/blob/v2/README.md) for previous versions

-    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/master/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
-
-Refer [here](https://github.com/actions/cache/blob/v1/README.md) for previous versions
 
 ## Usage
 
 ### Pre-requisites
 Create a workflow `.yml` file in your repositories `.github/workflows` directory. An [example workflow](#example-workflow) is available below. For more information, reference the GitHub Help Documentation for [Creating a workflow file](https://help.github.com/en/articles/configuring-a-workflow#creating-a-workflow-file).
 
+If you are using this inside a container, a POSIX-compliant `tar` needs to be included and accessible in the execution path.
+
 ### Inputs
 
-* `path` - A list of files, directories, and wildcard patterns to cache and restore. See [`@actions/glob`](https://github.com/actions/toolkit/tree/master/packages/glob) for supported patterns. 
+* `path` - A list of files, directories, and wildcard patterns to cache and restore. See [`@actions/glob`](https://github.com/actions/toolkit/tree/main/packages/glob) for supported patterns.
 * `key` - An explicit key for restoring and saving the cache
-* `restore-keys` - An ordered list of keys to use for restoring the cache if no cache hit occurred for key
+* `restore-keys` - An ordered list of keys to use for restoring stale cache if no cache hit occurred for key. Note

+## 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. 
+
+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`
