* (bug 14202) $wgUseTeX has been superseded by the Math extension. To re-enable math conversion after upgrading, obtain the Math extension from SVN or from http://www.mediawiki.org/wiki/Extension:Math and add to LocalSettings.php: require_once "$IP/extensions/Math/Math.php"; This is an initial stab, and a few things remain to be cleaned up: * messages need to be moved from core to extension * MW_MATH_* constants should be moved to the extension from core * old back-compat math names interfaces using those constants should be removed from message files * classic edit toolbar's math button should be added from the extension (or else dropped) -- currently there's not a clean hook, but could do it by JS * couple of things like the 'armourMath' function on Language & LanguageConverter may want to be redone just as an unconditional, if that's simpler. Setting $wgUseTeX alone will no longer have any affect. The var's still there for the moment as a few bits still need to be fully moved out from core.
