The beta stage is almost complete and WoltLab Suite will enter the Release Candidate (RC) phase on December 15th along with the previously announced upgrade of woltlab.com. This site will then be switched into archive mode, preventing any new content from being added, eventually being merged into the main site at a later point of time. This means that this site will continue to exist for some time after December 15th until the merge is performed.
For those of you that already have an account on woltlab.com, we kindly ask you to double-check the email address used and to ensure that both the account on woltlab.com and on this site match. The import will merge users based on their email address, while keeping the username from woltlab.com.
We would like to take this opportunity to express our eternal gratitude towards all users that have provided us with valuable feedback and reports during the whole beta phase. Your invaluable support has paved the way to build the most outstanding and awesome version ever released by us, pushing the limits of what communities can achieve by an order of magnitude. Thank you!

In response, I would again like to please ask that you please delay your schedule. While I do believe WoltLab Suite 3 has come a long way, I do not yet believe it is as ready to leave the testing phase. I suspect you're planning a short RC (release candidate) phase and plan to wrap up development into the final release this December 2016 (if not early January 2017).
I would very much like to see a stable release and not have this rushed to fulfill an internal deadline.
