Very good release so far. I have not seen any crashes and only a few minor error messages.
The Google offline calendars is working fine and syncing to my Blackberry. The APPTUNID field which can be used to filter them out programmatically at they contain the string ICALENDAR.
Traveler for the iPhone is working fine. Very easy to configure. I just need to work out how to switch iPhones to use a private APN and still have full Internet access.
One small issue is the Administration client stealing focus when switching between the Designer client and the Administration client. A workaround for this seems to be if you minimise the Admin client before switching to the Designer. This may be my machine as I have not seen this issue reported anywhere else.
Another problem is the setup program is not quick. It probably takes similar times to the previous client installs but on an older machine this does take some time. Fine if you are upgrading a low number of clients but resource intensive if you are upgrading thousands. I am looking at 3rd party tools to help automate this process.
