This morning, i also got a surprise from phpBB announcement mailing list saying that there is a new phpBB release which is a maintenance update for the previous 3.0.7-PL1, but it also contains one security fix which relates to BBCodes. The Changelog will list all changes (it contains a number of bug fixes and also improvements since last release) and it's recommended to be read before upgrading.
When i got this announcement, i grab the updated package and start upgrading Indonesian Linux Forum at 5.45 AM in the morning and the process was completed at 6.30 AM. I think not many people have accessed the board at that time, so 30 minutes of downtime will not affect too many people
Anyway, the forum is now back serving all of you and have a nice discussion on the forum
