CubeCart V4.2.3 has today (12:57 PM GMT) been released.  This latest release fixes over 60 reported bugs, patches the XSS vulnerability and adds a few extra payment modules.  There have been a significant number of changes to core PHP files.  As such, we strongly advise clients to avoid updating to the latest release before we publish compatible “Quick Upload” files and manual installation instructions for the Catalyst V4 skin.  We will post again when we have tested and released the Catalyst V4 skin with V4.2.3.

One thing to note is that it will be extremely difficult (and time consuming) to manually update from V4.2.2 to V4.2.3.  Hence, you will loose all modifications made to your store after you install the updated version.  If you have any questions, please drop us an email (or post a comment below).
