1.3.1 fixes some of the remaining problems in 1.3.0:
* Watchlist parameters now work with register_globals off * Fixed parsing of ''italics'' and '''bold''' mark-up (again) * Special:Allpages display is more sensible on smaller wikis * Fixed XHTML parsing error in classic skins * Moved pages update watchlist correctly * Fixed rebuildall.php on case-sensitive Unix filesystems * Disabled file cache compression by default due to incompatibility with output buffer compression (ob_gzhandler) * New magic word PAGENAMEE (URL-escaped version of PAGENAME) * Installation avoids blank username; better message on missing XML module * $wgWhitelistAccount no longer breaks all logins.
Anyone still running the 1.3 beta releases is _strongly_ recommended to upgrade to the current code due to numerous fixed bugs and a security vulnerability in the betas with some PHP configurations.
Note that while MediaWiki through 1.1 required register_globals to be on, 1.2 and 1.3 *do not*. If you have register_globals on, you should turn it off unless you are absolutely sure you require it for some other package. See http://php.net/register_globals for general information.
