I don't notice any changes. I think it was mostly bug fixes. http://www.vbulletin.com/forum/showthread.php?t=191318 doesn't say anything about new stuff being added.
Yep... that's what I'm thinking too... primarily bug fixes. I don't know of any new features between beta 4 and rc1.
I caved and installed 3.6 RC 1 tonight too. Seems to have gone well. All my custom code and hacks work.
Were you upgrading from 3.5.4, or a beta? I had a few plug-ins that didn't work between 3.5.4 and the 3.6 betas, but 95% of them worked.
I went from 3.5.4. I guess I should point out that while my template edits worked, some had to be relocated due to vB template changes. I'm running seven products on this board and two plugins. The products are about 21 plugins. I guess I got lucky and just plugged in the correct places. We're not talking about super complicated hacks either. Brian's CMPS My Quick ShoutBox My vBPicGallery photo gallery My postbit selector My RSS feeds in postbit A referals count and some code to make my adsense and ypn not show to me. Not a big deal. Now that I type it out, I'm not 100%. My code for conditional links in posts based on groups and post count was half baked and I didn't even try it on 3.6. Gotta work on that one.
