Just posted the update to Lite for VaultWiki 4 RC 3, which has been out 2 weeks now. It seems to have been a pretty stable release so far, so RC might be over soon. Even so, RC 3 did not change much compared to RC 2 when looking at the Lite version. It would seem that most of the core features are already pretty stable, and that mostly non-Lite features have been having problems.
Here's some of the relevant bits for Lite:
(released September 23, 2014)
- Fixed dynamic scripts always loading from CDNs
- Fixed a lot of missing phrases
- Fixed blank moderator notifications
- Fixed integrity of moderated content
- About 35 other bugs that weren't limited to vBulletin (or Lite) are fixed
