Hello everyone,

in new version of MediaWiki the $user->isSysop() function is deprecated. Can anybody tell me, what can I use instead of this ???

Generally you'd $wgUser->isAllowed(), passing the particular permission key you're looking for (which could be conferred by any number of groups, not just the old hard-coded "sysop").
