No the BETA is not done.
However, it seems there were a lot of coaches who signed up for the BETA and were no longer participating. In the first few season, seble helped those coaches who didn't bother to add addtional seasons using the HDBETA free code to grab extra seasons and just continually signed coaches back up to their old teams.
However, doing so for ghost shipped coaches didn't help in recruiting as we're having to deal with teams with 6 or more walk ons which are skewing data so this season seble decided NOT to automatically renew people.
Use the HDBETA code and grab a 10 season pack (which is still free) and sign up for a school if you want to continue playing in the BETA.
