Has it already been 4 weeks since our last upgrade? Yep. That means it’s time to announce some new enhancements then.

v6.2 is going live today, and — you should know the drill by now — the new features should be done propagating to all user accounts by end of day tomorrow. We’ll be blogging about them in more detail soon, but here’s a list of some of the new features:

• Google+ sharing available on email archive toolbars, plus new Google+ buttons can be added to your campaigns [documentation]
• Tumblr share button can be added to your campaigns [documentation]
• OAuth2 support is now available for all you API and app developers [important information for devs]
• 42 beautiful new templates added, AND remember those premium designer templates we launched a while back? They’re free now.
• Embedded signup form code has been slimmed down, optimized, and less “JavaScripty.”
