"MySQL Server is and will always remain fully functional and open source," said Kaj Arno, MySQL's vice president of community relations, in a statement released on his website on Tuesday. "So will the MySQL Connectors, and so will the main storage engines we ship."
In effect, MySQL has changed its plans for forthcoming encryption and compression backup features that it had planned to ship under a proprietary licence, and will now release the features with open-source licences, Arno said. He also confirmed that pending backup functionality in MySQL 6.0 and the MyISAM driver for MySQL Backup will be open source.
The announcement is a step back from plans announced last month by Marten Mickos, former chief executive of MySQL and now a Sun vice president.
