Issues solved in this release:

• Counters: Scylla rejects SSTables that contain counters that were created by Cassandra 2.0 and earlier. Due to #4206, Scylla mistakenly rejected some SSTables that were created by Cassandra 2.1 as well.
• TLS: Scylla now disables TLS1.0 by default and forces minimum 128 bits ciphers #4010. More on encryption on transit (client to server) here.
• Core: In very rare cases, the commit log replay fails. Commit log replay is used after a node was unexpectedly restarted #4187
• Streaming: in some cases, Scylla exits due to a failed streaming operation #4124
• A rare race condition between a node restart and schema updates may cause Scylla to exit #4148
