CONJS-143 is a breaking change. Queries that have a IN parameter with array parameters format change. previous format did not accept parenthesis :

conn.query('SELECT * FROM arrayParam WHERE id = ? AND val IN ?', [1, ['b', 'c']]);

now, format is

conn.query('SELECT * FROM arrayParam WHERE id = ? AND val IN (?)', [1, ['b', 'c']]);

same than mysql/mysql2 drivers. previous behaviour can be reverted setting option arrayParenthesis to true.

Bugs Fixed

• CONJS-145 - batch rewrite error when packet reach maxAllowedPacket

• CONJS-146 - Using callback API, batch, avoid return error if connection not established

• CONJS-144 - TypeScript type ssl wrong definitions
