+The `rippled` 0.50.2 release adjusts the default TLS cipher list and corrects a flaw that would not allow an SSL handshake to properly complete if the port was configured using the `wss` keyword. Ripple recommends upgrading to 0.50.2 only if server operators are running rippled servers that accept client connections over TLS.

 ## Version 0.50.0
 
 The `rippled` 0.50.0 release includes TickSize, which allows gateways to set a "tick size" for assets they issue to help promote faster price discovery and deeper liquidity, as well as reduce transaction spam and ledger churn on RCL. Ripple expects TickSize to be enabled via an Amendment called TickSize on Tuesday, 2017-02-21.
