Beta 2 is now available for download either directly from here or by updating via your Plugins page in your wp-admin area. I want to extend a very big thank you to everyone who took the time to test and report issues! Without you guys this would have taken much more time! Thank you!
If you have made any customizations for the Sell Content add-on, Badges or Ranks add-ons, you should test 1.7 before it goes live to make sure your customizations does not break your site as you update. This is particularly important for the Sell Content add-on as it has been completely re-written!
