This release has been solid and MAJOR users will be updated on July 6.
However MAJOR auto-update in Australia could experience a problem with this update due to suspected problems with internet delays. See this post:
The problem is only in Australia, and appears that all affected systems have resolved at this point. Australian MAJOR users that want to avoid a problem can set auto-update to NONE and perform a manual update as described in the link. If you need help with that, please ask in that forum thread.
