ScyllaDB Open Source Release 2.3.5

ScyllaDB Open Source Release 2.3.5, announced by Tzach Livyatan on April 18, 2019, is a bugfix update for the ScyllaDB Open Source 2.3 stable branch, ensuring backward compatibility and supporting rolling upgrades. Although users are encouraged to upgrade to the latest stable branch, release 3.0, this update addresses specific issues such as a CentOS 7 setup error due to a change in EPEL, potential disk space doubling during nodetool cleanup, indefinite delays in schema change statements with constant schema pulls, exceptions in JSON serialization of decimal and variant data types, and potential aborts in row_cache during concurrent MemTable flushes. The release is available in Docker and binary packages, and users are invited to report any issues encountered.
