[Appointments+] Appointments + date problem at daylightsaving time changes

At each daylight savings i have problem with all appointments made before the change but taking place after the change. Befor time change everything is fine, after the time change all existing appointments are shifted by one our in the google calendar...

In addition, recently a couple appointments were canceled without the person clicking the link.

I just upraded from v 1.4.x Does this solve any of the above issues?
Best Regards
André
