A new update to SMF has been released, so the forums will need to be updated to it at some point. As always, due to the customizations and the use of addons (some of which have had to be installed manually and modified to be 2.1 compatible), it's not going to be as straightforward as just running the auto-update; but I'll look at sorting this update in the near future.
At this time I have no expected dates or other further details to share.
