Hi,
I'm currently using 2.2RC4. I was able to find the change logs on forge for 2.2 stable and 2.2.2, but I didn't see anything on 2.2.1 or 2.3. Also, I don't know if there was a release between 2.2RC4 and 2.2 stable?
The changes that I do see were minor bug fixes. None of which would cause me to upgrade. Do you have details on the other releases? If there was a security related update, what was it's nature and was it a critical update?
Recently (in the past year or so), I've been seeing more malicious registrations that may be bypassing Captcha. One of them appears to have been via Xrumer. I've changed settings to force admin approval for all registration requests. Has any work been done to strengthen the extension to prevent circumvention?
Thanks for your help!!
