 You can now create a free database from the [Create a database]({{< relref "/operate/rc/databases/create-database/create-free-database" >}}) page. Free databases are perfect for learning and exploring Redis. You get 30 MB of space for you to learn Redis concepts and develop application prototypes.
 
 You can only have one free database per account. If you already have a free database, you can [delete it]({{< relref "/operate/rc/databases/delete-database" >}}) or [upgrade it to a paid Essentials plan]({{< relref "/operate/rc/subscriptions/view-essentials-subscription#upgrade-plan" >}}) before creating a new one.

+### Faster scaling with Redis hashing policy
+
+Starting June 24, 2025, accounts with the [Redis hashing policy]({{< relref "/operate/rc/databases/configuration/clustering#redis-hashing-policy" >}}) can create databases that scale faster. This makes resharding operations up to 40% faster than before.
+
+Faster scaling requires a new database created after June 24, 2025, running Redis 7.4 or later, with the [Redis hashing policy]({{< relref "/operate/rc/databases/configuration/clustering#redis-hashing-policy" >}}) selected.
+
+For these databases, this enhancement is enabled automatically, ensuring that all future resharding operations complete faster than ever.

 ### Standard hashing policy
 
 The Standard hashing policy is mostly consistent with the Redis hashing policy, and will generate the same hash-slot calculation in the following cases:
