ScyllaDB Release 2.1.2

ScyllaDB 2.1.2, released by the ScyllaDB team, is a bugfix update for the ScyllaDB 2.1 stable branch, ensuring backward compatibility and support for rolling upgrades. This update addresses several issues, including problems with view entries having non-composite, empty partition keys, and node removal failures during the bootstrap process. It also resolves a TLS session closure error, a NullPointerException with nodetool gossipinfo during cluster initialization, and limitations in stableloader and sstableloader concerning user-defined types and binding prepared statements for tables using the "date" type. Users are encouraged to report any problems encountered with the release, available through Docker, binary packages, and EC2 AMI.
