That means a few things:
-There will be new features to play around with
-A new theme, as this one is not carried over to the new version. I'll try to get one as close as possible so it's not a massive jump (new things are scary right?

-Hopefully i'll be able to re-enable automatic forum user authentication again, so we don't get people slipping between the cracks anymore.
-It will be mobile friendly
-The forum will be down for maintenance on the 30th March for probably a few hours, so make sure you aren't reliant on the forums in that time.
The main reason we're doing this is because the current version is unsupported, so there are no more security patches coming out for it.
All of your posts, PMs etc etc will all remain.
