 ## What's New
 
-### v4
+### ⚠️ Important changes
 
-* Updated to node 20
-* Added a `save-always` flag to save the cache even if a prior step fails
+The cache backend service has been rewritten from the ground up for improved performance and reliability. [actions/cache](https://github.com/actions/cache) now integrates with the new cache service (v2) APIs.
+
+The new service will gradually roll out as of **February 1st, 2025**. The legacy service will also be sunset on the same date. Changes in these release are **fully backward compatible**.
+
+**We are deprecating some versions of this action**. We recommend upgrading to version `v4` or `v3` as soon as possible before **February 1st, 2025.** (Upgrade instructions below).
+
+If you are using pinned SHAs, please use the SHAs of versions `v4.2.0` or `v3.4.0`
+
+If you do not upgrade, all workflow runs using any of the deprecated [actions/cache](https://github.com/actions/cache) will fail.
+
+Upgrading to the recommended versions will not break your workflows.
+
+Read more about the change & access the migration guide: [reference to the announcement](https://github.com/actions/cache/discussions/1510).
 
 ### v3
 
+* Integrated with the new cache service (v2) APIs.
 * Added support for caching in GHES 3.5+.
 * Fixed download issue for files > 2GB during restore.
 * Updated the minimum runner version support from node 12 -> node 16.
