Scylla Open Source 3.1.2

The ScyllaDB team announces the release of Scylla Open Source 3.1.2, a bugfix release of the Scylla 3.1 stable branch. Scylla Open Source 3.1.2, like all past and future 3.x.y releases, is backward compatible and supports rolling upgrades.

Note: if and only if you installed a fresh Scylla 3.1.0, you must add the following line to scylla.yaml of each node before upgrading to 3.1.2:

enable_3_1_0_compatibility_mode: true

This is not relevant if your cluster was upgraded to 3.1.0 from an older version, or you are upgrading from or to any other Scylla releases, like 3.1.1.
If you have doubts, please contact us using the user mailing list.
