At the time there were a few bugs we needed that were not in the standard version so we had to fix them in custom version. I think at the time the log rolling was not working. Not sure what else. I wasn't involved in this part of system at that time. There was also other things added. We worked with Maurizio who gave us the build environment. I heard that we didn't need to do a newer build as there were not many changes. But now we do (need to update a lot of things). Yes we will be rebuilding latest version into our own custom (if still needed - have to check this)
