This file should contain all known fatal bugs in Mariadb and the Aria storage engine for the last source or binary release. Minor bugs, extensions and feature requests, and bugs found since this release can be found in the MariaDB bugs database at: http://mariadb.org/jira and in the MySQL bugs databases at: http://bugs.mysql.com/ (category "Maria storage engine"). There should not normally be any bugs which affect normal operations in any MariaDB release. Still, there are always exceptions and edge cases and that is what this file is for. If you have found a bug that is not listed here, please add it to http://mariadb.org/jira so we can either fix it for next release or in the worst case add it here for others to know! IMPORTANT: If you have been using the Maria (now Aria) storage engine with the MySQL-5.1-Maria-alpha build and are upgrading to a newer MariaDB you MUST run [m]aria_chk --recover on all your Aria tables. This is because we made an incompatible change with how the transaction id is stored and old transaction id's must be reset! cd mysql-data-directory aria_chk --recover */*.MAI Going forward, we will do our best to not introduce any incompatible changes in the data format for Aria tables. If this would be ever be needed, we will, if possible, support both the old and the new version to make upgrades as easy as possible. Note that for the MariaDB 5.1 release the Aria storage engine is classified as 'beta'; It should work, but use it with caution. Please report all bugs to http://mariadb.org/jira so we can fix them!
