Whoo, there's a face I haven't seen in a while. I was actually wondering where you'd gone, earlier today. I'm glad the new year has brought our YoHoJo back (for good?)
As far as new stuff, SRL-6 really =/= SRL-5 in a lot of ways. Lape has changed the game pretty significantly. A full reinstall of Simba is recommended.
Some important stuff would be:
Simba 1.1 release (changelogs and new release information),
Simba Buildbot news (developer stuff, info on future releases),
Setting up RS (has changed a bit since SRL-5),
The Mayor's SRL-6 tutorial (great for getting on your feet with SRL-6),
and
SMARTv8.3 which you may or may not already be familiar with.
Oh yeah, and if you plan on using SPS-RS3 anytime soon, be sure to check
this out.
Some of those links might be more useful than others, dunno. Others might have more to add, that's just what I could remember off the top of my head.
Welcome back and happy new year!
Edit: Oh! Two more things I forgot!
Coh3n's guide to using SRL-6 which provides a look at some of the more fundamental aspects of SRL-6 and Lape,
and
libSRL5 which is Markus's include for porting SRL-5 scripts to SRL-6
