There is a forum-wide announcement in the above-mentioned forum, which says that a beta is available. Meanwhile, the Overview tab has an additional (newer) announcement that the full software is now available.
As I have Discussions set as the default tab, I'm still led to believe the beta is current (and only found out about the new software by accident). This doesn't seem a very smart/consistent way to make announcements on the new forum software.
Moderators and some employees have control over announcements. However, the moderator's are volunteers and do this in their spare time. Most employees that visit the forums do so on their own time as well. Hopefully, your post will stir one of the more knowledgeable hosts that visit the raw forum to adjust the announcement appropriately. Thanks for the heads up.
