Jam's going well, and plenty of time to still make something if you want to!
One common pitfall is you really do need to upgrade to Decker 1.65. I've seen a couple of cases where people have started work in an older version, and aside from some of the print functionality being a bit borked it seems to break some of the modules and contraptions, so even if they do update there'll still be a few things that have gone funny. So it's a good idea to update before starting any work.
