 ## Upgrading
 
+### To 26.0.0
+
+This major updates the Redis&reg; subchart to its newest major, 21.0.0, which updates Redis&reg; from 7.4 to 8.0. [Here](https://redis.io/docs/latest/operate/oss_and_stack/install/upgrade/cluster/) you can find more information about the changes introduced in that version. No major issues are expected during the upgrade.
+
 ### To 25.0.0
 
 This version uses the PostgreSQL version provided by the bitnami/postgresql subchart, PostgreSQL 17.x, instead of overriding it with version 14.x.
