Updated Heroku Key-Value Store version support policy

Change effective on 01 July 2025

We updated our Heroku Key-Value Store version support policy to support the latest 2 major versions with at least one minor version per major version. With this change, Heroku will automatically update minor versions through scheduled maintenance events. Customers will still upgrade to new major versions with redis:upgrade. This policy change will start when we release Valkey 8 on Key-Value Store.

For example, under the new policy:

  • When we release major version 8, we support versions 8 (8.1) and 7 (7.2). We automatically upgrade instances on minor version 7.0 to 7.2.
  • When we release minor version 8.2, we support versions 8 (8.2) and 7 (7.2). We automatically upgrade instances on minor version 8.1 to 8.2.
  • When we release major version 9, we deprecate major version 7 and support versions 9 (9.x) and 8 (8.2).

You can find new major version and version deprecation announcements in the Changelog.
