Surely 1.18 doesn't make sense. I don't know what happened here, wasn't it one of the last available in the pseudo-dropdown, like 1.20-git (when it existed) or unspecified? Or perhaps I'm confusing it with extensions which use "master" as default.
There is no default version (it's not even possible for Versions).
Thanks. Indeed this is WONTFIX upstream. However, the problem is rather that I had a cookie (expiring in 2038!) storing 1.18 as my MediaWiki version, and bugzilla picked that.
