One of the things the update does is to replace the old HTML web engine that I had modified to get around the "bin" problem that my ISP doesn't like! While it was only a minor thing, it still meant I had to go back and swap out the LRWEB file, Grid, and Details files for the modified ones. This is one thing that the Lightroom engineers should fix in a future update as most any ISP that uses the Windows interface doesn't like the "bin" file folder.
