Both of my boards are 6.1.0.4 and really stable. *crosses fingers* I installed the first beta of 6.2 and played with the templates a bit but I haven't even downloaded the new beta.
I think it's gonna be a great release version but I already have the features I need hacked in. I'm sure I'll build a board on my local test server but I doubt I'll be upgrading anytime soon. I'm trying to get over the need to upgrade just to upgrade. I feel really good about the security of the current release, and that has been my biggest concern in previous upgrades.
