I can confirm: we don’t have a specific date.
freeCodeCamp is a volunteer-driven community. Volunteerism should be as fun and stress-free as possible. So we don’t impose deadlines on our contributors.
Instead, we try to break tasks down into as small bits as possible - and make them as independent from other tasks as possible - so that hundreds of people can work on different tasks in parallel.
We are making progress toward shipping the new beta certificates. I just can’t give you a specific release date, because even I have no idea how soon all the tasks necessary will be done.
What I can tell you is we can definitely use help, and if you’re interested in contributing, check out https://www.freecodecamp.org/contribute
