+See ["Caching dependencies to speed up workflows"](https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows).
 
 ## 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`.
+* Fixed zstd failing on amazon linux 2.0 runners.
+* Fixed cache not working with github workspace directory or current directory.
+* 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.
 
-* 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@v2
-  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

 ## 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/main/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 prefix-matched keys to use for restoring stale cache if no cache hit occurred for key.
+
+#### Environment Variables
+* `SEGMENT_DOWNLOAD_TIMEOUT_MINS` - Segment download timeout (in minutes, default `60`) to abort download of the segment if not completed in the defined number of minutes. [Read more](#cache-segment-restore-timeout)
 
 ### Outputs
 
-* `cache-hit` - A boolean value to indicate an exact match was found for the key
+* `cache-hit` - A boolean value to indicate an exact match was found for the key.

+## 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.

+```yaml

+
+### 3.0.2
+- Added support for dynamic cache size cap on GHES.
+
+### 3.0.3
+- Fixed avoiding empty cache save when no files are available for caching. ([issue](https://github.com/actions/cache/issues/624))
+
+### 3.0.4
+- Fixed tar creation error while trying to create tar with path as `~/` home folder on `ubuntu-latest`. ([issue](https://github.com/actions/cache/issues/689))

+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`

+#### Cache segment restore timeout
+A cache gets downloaded in multiple segments of fixed sizes (`1GB` for a `32-bit` runner and `2GB` for a `64-bit` runner). Sometimes, a segment download gets stuck which causes the workflow job to be stuck forever and fail. Version `v3.0.8` of `actions/cache` introduces a segment download timeout. The segment download timeout will allow the segment download to get aborted and hence allow the job to proceed with a cache miss.
+
+Default value of this timeout is 60 minutes and can be customized by specifying an [environment variable](https://docs.github.com/en/actions/learn-github-actions/environment-variables) named `SEGMENT_DOWNLOAD_TIMEOUT_MINS` with timeout value in minutes.
+
+#### Update a cache
+A cache today is immutable and cannot be updated. But some use cases require the cache to be saved even though there was a "hit" during restore. To do so, use a `key` which is unique for every run and use `restore-keys` to restore the nearest cache. For example:
+  ```yaml
+      - name: update cache on every commit
+        uses: actions/cache@v3
+        with:
+          path: prime-numbers
+          key: primes-${{ runner.os }}-${{ github.run_id }} # Can use time based key as well
+          restore-keys: |
+            primes-${{ runner.os }}
+  ```          
+  Please note that this will create a new cache on every run and hence will consume the cache [quota](#cache-limits).
+  
+#### Use cache across feature branches
+Reusing cache across feature branches is not allowed today to provide cache [isolation](https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#restrictions-for-accessing-a-cache). However if both feature branches are from the default branch, a good way to achieve this is to ensure that the default branch has a cache. This cache will then be consumable by both feature branches.
+
+#### Improving cache restore performance on Windows/Using cross-os caching
+Currently, cache restore is slow on Windows due to tar being inherently slow and the compression algorithm `gzip` in use. `zstd` is the default algorithm in use on linux and macos. It was disabled on Windows due to issues with bsd tar(libarchive), the tar implementation in use on Windows. 
+
+To improve cache restore performance, we can re-enable `zstd` as the compression algorithm using the following workaround. Add the following step to your workflow before the cache step:
+
+```yaml
+    - if: ${{ runner.os == 'Windows' }}
+      name: Use GNU tar
+      shell: cmd
+      run: |
+        echo "Adding GNU tar to PATH"
+        echo C:\Program Files\Git\usr\bin>>"%GITHUB_PATH%"
+```
+
+The `cache` action will use GNU tar instead of bsd tar on Windows. This should work on all Github Hosted runners as it is. For self-hosted runners, please ensure you have GNU tar and `zstd` installed.
+
+The above workaround is also needed if you wish to use cross-os caching since difference of compression algorithms will result in different cache versions for the same cache key. So the above workaround will ensure `zstd` is used for caching on all platforms thus resulting in the same cache version for the same cache key.
