This version fix a problem when replicating a website into a DB located in another server than the "source" db server.
In JMS 1.2.3, JMS now checks that the "target" DB already exists when present in another server to avoid trying create a DB located on the same server than the DB to replicate.

So now when you want to replicate a website into a DB created in another DB server, this is possible.
You just have to create the DB manually on this "target" server.

This JMS version is also bundled with the "Patch Definition" version 1.2.6 that Add sharing definition for QuickFAQ extensions.
