These are three patches for the just-released MediaWiki 1.4rc1.
The first two should be un-controversial, I think.
* A typo in language/Language.php ("dismbiguations" instead of "disambiguations")
* Change "FROM links as la, links as lb, cur as ca, cur as cb" to use $links and $cur in includes/SpecialDisambiguations.php (otherwise the page throws an error).
The third patch makes two changes to maintenance/tables.sql, following the thread at http://mail.wikipedia.org/pipermail/mediawiki-l/2005-February/003367.html:
* A little change to the cl_sortkey index from the categorylinks table so MediaWiki can be installed on MySQL 4.1 when utf-8 is the default charset. Without the patch, the install script fails because the index is longer than 1024 bytes.
* Forcing the log_title column from the logging table to be binary. This is part of Brion Vibber's patch for bug 1057. I haven't tried the rest of his patch because I modified the tables by hand, but at least this part helps with new installations (though I agree that the rest of his patch should also be included so people can upgrade; I'm just not knowledgeable enough on PHP and MediaWiki).
