ScyllaDB Open Source 3.0.11

The ScyllaDB team announces the release of ScyllaDB Open Source 3.0.11, a bugfix release of the ScyllaDB 3.0 stable branch. ScyllaDB Open Source 3.0.11, like all past and future 3.x.y releases, is backward compatible and supports rolling upgrades.

Please note the latest stable ScyllaDB release is ScyllaDB 3.1.2, and it is highly recommended to upgrade. Once ScyllaDB 3.2 will be released, support for ScyllaDB 3.0.x will be dropped.

ScyllaDB 3.0.11 is not available for Ubuntu 14. A problem in the build process stops us from build images ScyllaDB 3.0.11 images for it. Until this is solved, please consider upgrading ScyllaDB server to Ubuntu 16.
