MediaWiki 1.5 beta 2 is a preview release of the new 1.5 release series. While most exciting new bugs should have been ironed out at this point, third-party wiki operators should probably not run this beta release on a public site without closely following additional development.
Anyone who _has_ been running beta 1 is very very strongly advised to upgrade to beta 2, as it fixes many bugs from the previous beta including a couple of HTML and SQL injections.
This release should be followed by one or two release candidates and a 1.5.0 final within the next few weeks.
Beta upgraders, note there are some minor database changes. For upgrades from 1.4, see the file UPGRADE for details on significant database and configuration file changes.
Beta 2 includes a preliminary command-line XML wiki dump importer tool, maintenance/importDump.php, paired with maintenance/dumpBackup.php. These use the same format as Special:Export and Special:Import, able to package a wiki's entire page set independent of the backend database
and compression format.
