I was wondering where I could get the "updated" version of this style so it works with 3.5.x. I had 3.0.11 and it worked great, but I just upgraded and noticed some problems with it.
Thanks.

Not off the top of my head. I would suggest keeping an eye on the release thread and cross your fingers that Zack decides to update his style. :)

Is there a big change going from 3.5.3 to 3.5.4? Just wondering cause maybe I could get the theme on here exported for download?

Just for information purposes. It was running good on one of my 3.5.2 forums. So I exported it, changed the .xml file to read 3.5.4 and imported it and it seems to work fine.
Thanks for the help.

Glad to hear it is working well. :)

The real big change came between 3.0.x and 3.5.x. So if you have it working on a 3.5.2 board then it should still be ok on 3.5.4. ;)
