New Features

• Add method Client#ssl_cipher to expose mysql_get_ssl_cipher
• Add method Result#free to immediately free a result set
• Add connection flag automatic_close: true/false to determine whether to work around connections being closed by garbage collection in a child after a fork. Default is true, which restores behavior prior to 0.3.16.

Bugfixes

• Fix to hold the GVL between mysql_stmt_execute and mysql_stmt_store_result to prevent commands hitting the wire out of sync (e.g. if a GC run occurs in the middle)
• Fix BigDecimal arguments to Prepared Statements were ignored
• Fix rake re-definition warning

Changes

• Add Ruby 2.3 to the Travis CI matrix
• Allow nil for timeouts instead of casting to 0 when creating a Client instance
• Add connection flag automatic_close: true/false to determine whether to work around connections being closed by garbage collection in a child after a fork. Default is true, which restores behavior prior to 0.3.16.
