Yes, it's still beta. I've started the new release but it's more work than I thought. I'm also working on a small contrib for motion (video supervision), and I've just finish corecting my first contrib backuppc, so the development of openvpn's one has been slow down. But I use this beta on 3 prod servers and I haven't any problem for more than two months. If you use the server&gateway mode, I think you can use this.
There's one thing you must take care (but this were present in the base of the contrib): you must not restart dhcpd service while openvpn is running. If you do, dhcpd wont start corectly, and it will fill the messages log very quickly (more than 700 Mo per day) and this can slow down the server. I'll try to correct this.
