 ## Documentation

 See ["Caching dependencies to speed up workflows"](https://help.github.com/github/automating-your-workflow-with-github-actions/caching-dependencies-to-speed-up-workflows).

+## What's New
+
+* 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
+      **/node_modules
+    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
+
+Refer [here](https://github.com/actions/cache/blob/v1/README.md) for previous versions

 ### Inputs

-* `path` - A directory to store and save the cache
+* `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

+## Creating a cache key
+
+A cache key can include any of the contexts, functions, literals, and operators supported by GitHub Actions.
+
+For example, using the [`hashFiles`](https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#hashfiles) function allows you to create a new cache when dependencies change.
+
+```yaml
+  - uses: actions/cache@v2
+    with:
+      path: | 
+        path/to/dependencies
+        some/other/dependencies 
+      key: ${{ runner.os }}-${{ hashFiles('**/lockfiles') }}
+```
+
+Additionally, you can use arbitrary command output in a cache key, such as a date or software version:
+
+```yaml
+  # http://man7.org/linux/man-pages/man1/date.1.html
+  - name: Get Date
+    id: get-date
+    run: |
+      echo "::set-output name=date::$(/bin/date -u "+%Y%m%d")"
+    shell: bash
+
+  - uses: actions/cache@v2
+    with:
+      path: path/to/dependencies
+      key: ${{ runner.os }}-${{ steps.get-date.outputs.date }}-${{ hashFiles('**/lockfiles') }}
+```
+
+See [Using contexts to create cache keys](https://help.github.com/en/actions/configuring-and-managing-workflows/caching-dependencies-to-speed-up-workflows#using-contexts-to-create-cache-keys)
+
 ## Cache Limits

 A repository can have up to 5GB of caches. Once the 5GB limit is reached, older caches will be evicted based on when the cache was last accessed.  Caches that are not accessed within the last week will also be evicted.

 Depending on the environment, huge packages might be pre-installed in the global cache folder.
-If you do not want to include them, consider to move the cache folder like below.
+With `actions/cache@v2` you can now exclude unwanted packages with [exclude pattern](https://github.com/actions/toolkit/tree/main/packages/glob#exclude-patterns)
+```yaml
+- uses: actions/cache@v2
+  with:
+    path: | 
+      ~/.nuget/packages

+    restore-keys: |

+
+Or you could move the cache folder like below.

 For npm, cache files are stored in `~/.npm` on Posix, or `%AppData%/npm-cache` on Windows. See https://docs.npmjs.com/cli/cache#cache

+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`
