I didn't see these Froyo changes to the calendar mentioned in the other Froyo threads. 1- "My Calendar" (light blue) is now gone. I used to use this for events that I did not want to sync with Google calendars or Outlook on my laptop. Now only "PC Sync" (green), the default and custom Google calendars (various user defined colors) including US Holidays (red) and Facebook (dark blue) are still there in the "Calendars" screen. 2- The "Calendars" screen itself changed in the way it lists the various Calendars, breaking them down by Google calendars, PC Sync and Facebook below that. 3- The color bars next to the entries in the agenda view of the Calendar widget and agenda view of the Calendar itself are slightly different, specifically lighter and more washed out. 4- When you select a "PC Sync" Calendar entry, events now include text that says "firstname.lastname@example.org;". 5- In the Event Details view, "Edit event" is now missing if one is listed as "attending" the event. You must instead long press it in the agenda view to edit it. I am not sure yet why some of my events list me as attending and others do not. 6- Event Details view for events has an agenda view option.
