If you're like me and want to play with the new osTicket 1.8rc2 you may encounter the following upgrade error:
Fatal error: Call to undefined method Upgrader::getPendingTask() in PATHTOscpupgrade.php on line 38
I reported the bug this morning and the devs already patched and fixed it. If you use git simply do a "git pull" request and it will pull down the fix for you. Other wise re-download the latest 1.8 from github.
