ScyllaDB's release of Open Source 3.0.6, announced by Tzach Livyatan on May 7, 2019, is a bugfix update for the ScyllaDB Open Source 3.0 stable branch that maintains backward compatibility and supports rolling upgrades. This version addresses several issues, including incorrect IP addresses being printed during CQL batch operations, malfunctioning secondary indexes for clustering keys during updates, potential doubling of disk space usage during nodetool cleanup, and various schema change problems such as race conditions and indefinite delays in schema change statements. Additionally, it fixes a memory allocation error and an issue where resharding could cause ScyllaDB to exit unexpectedly. The release is available through Docker, binary packages, and EC2 AMI, and users are encouraged to report any problems encountered.
