1.1.0-beta Release date: no released yet, planned for 09/2011 Motto/theme: Cover replication basics with production quality The 1.1 and 1.0 series expose a similar, although not identical, feature set to the user, as can be guessed from the release motto/theme. Internally, the 1.1 series has been refactored significantly to prepare for future feature additions. A new configuration file format has been introduced and, limitations have been lifted. Code quality and quality assurance have been improved. Feature changes Added the (chainable) filter concept: BC break: mysqlnd_ms_set_user_pick_server has been removed. The user filter has been introduced to replace it. The filter offers almost the same functionality, see below for a discussion of differences. New powerful JSON based configuration syntax. Lazy connections improved: security relevant, state changing commands covered. Support for (native) prepared statements. New statistics: use_master_guess, use_slave_guess. BC break: Semantics of statistics changed for use_slave, use_master. Future changes are likely. Please see, mysqlnd_ms_get_stats. List of broadcasted messages extended by ssl_set. Library calls now monitored to remember settings for lazy connections: change_user, select_db, set_charset, set_autocommit. Bug fixes Fixed PECL #22724 - Server switching (mysqlnd_ms_query_is_select() case sensitive) Fixed PECL #22784 - Using mysql_connect and mysql_select_db won't work Users of the function mysqlnd_ms_set_user_pick_server need to update their code. The function has been removed in favor of a new user filter. You can no longer set a callback function using mysqlnd_ms_set_user_pick_server at runtime but have to configure it in the plugins configuration file. The user filter will pass the same arguments to the callback as before. Therefore, you can continue to use the same procedural function as a callback.callback It is no longer possible to use static class methods or class methods of an object instance as a callback. Trying to do so, will make any function executing a statement handled by the plugin emit a E_RECOVERABLE_ERROR level error like (mysqlnd_ms) Specified callback (picker) is not a valid callback. Please, note that this may halt your application.

1.0.1-alpha Release date: 04/2011 Motto/theme: bug fix release 1.0.0-alpha Release date: 04/2011 Motto/theme: Cover replication basics to test user feeedback First release of practical use. Features basic automatic read-write splitting, SQL hints to overrule automatic redirection, load balancing of slave requests, lazy connections and, optional, automatic use of the master after the first write. The public feature set is close to that of the 1.1 release. 1.0.0-pre-alpha Release date: 09/2010 Motto/theme: Proof of concept Initial check-in. At this stage the plugin is hardly of any practical use but a demo of the mysqlnd plugin API.
