+## What's New
+
+* Added support for multiple paths, [glob patterns](https://github.com/actions/toolkit/tree/master/packages/glob), and single file caches. 
+
+```yaml
+- name: Cache multiple paths
+  uses: actions/cache@v2

+      ~/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/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

+## 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.
