As FANDOM is not doing regular code releases over the winter break - noted in Thread:1356323 - we will use this thread to list notable bug fixes and changes that are released during the next few weeks.
BUGFIX: We fixed an issue where 'og:image' (the image used to represent an article in the Fan Feed and on some external sites) was picking the wrong image.
BUGFIX: We fixed an issue that caused Special:AdminDashboard 'Quick Stats' to be unavailable.
BUGFIX (December 20): On deleted Discussions posts, the name of the deleting user is displayed once again.
Whatever you may be doing, we wish you all Happy Holidays!
More specifically, it's plopping a message titled "Something interfered with this website loading", and demands that I post a message on the adblock user forums - despite the fact that I'm not using adblock on that browser. (Rather, I'm using NoScript, which only allows whitelisted sites to do funny stuff with pages.)
