XenForo 1.3.0 beta 4 is available. There weren't any major changes, so I've decided not to update beta styles right now. I want to add more stuff before releasing next version of my styles. You can use styles for beta 3 with beta 4. When using beta 3 styles with beta 4 XenForo will notify you that several templates are outdated, but you can just ignore that message. Do not revert outdated templates!
