Version 7.3.1 has been released; the most significant change is that the secure sockets code now defaults to TLS 1.0 rather than SSLv3. With the recent POODLE exploit, many browsers have begun removing support for SSLv3, and so if you're running your server encrypted, you'll want to update.
This version also incorporates the licensing changes discussed in the previous post. Essentially, if you had a license key valid for releases up to 2013 or later, you can use this version. If you've got an older license key, please contact us about upgrading.
Also, if you don't want to upgrade from an older version but still want to be able to use encrypted connections, you can think about proxying ProjectForum behind another web server.
