Is there a changelog for the 1.2.1 release somewhere? I haven't found one in the .zip file anywhere, and the announcement forums are empty or have no posts since 2006.

We are using CB 1.2 w/ CBLogin but a custom signup module that we have created, along with a CB plugin that handles user login/logout/creation/deletion integration with our shopping cart.

The 1.2 to 1.2.1 upgrade has broken the signup process. Something explaining what is changing between different versions would be very helpful when it comes to problems like this, or even deciding to upgrade or not; if there are no critical security issues, we would rather leave the version we have.

What you can do in the mean time is install a fresh setup of Joomla, and install CB 1.2.

Then install another fresh setup of Joomla to a different folder, and install CB 1.2.1

Then use a program like BeyondCompare2 to compare the folder/file structure, and you'll see what has been changed.

Furthermore, you'll want to export the database from each Joomla setup to a .sql file, and compare the two .sql files to see if any fields were changed, added, or removed.
