Ernie Cline helped get calendar working on Mac OS X 10.2. This is
untested, so there may be small installation problems.
Mostafa added in support for multiple calendar files.
Work progressed quickly after that and support for remote calendar files
was added. The files are downloaded and then added as a server,
allowing you to view the events. (You can't add / edit or delete them
yet). This allows you to subscribe to remote calendars, and see the
events of other people. The code for publishing this calendar back to a
server is there, but UI work needs to be done.
A list of bugs that were fixed: 163295, 164127, 158510, 157269, 160378,
164286, 164287, 164497, 164370, 164598, 164838, 164436, 164435, 164346.
A lot of those bugs were small issues that were added with remote
calendars.
Highlights of those bugs: Multiple selection for deleting both tasks
and events. Also, deleting multiple events is now faster since it
doesn't refresh the views until after it deletes all the events.
Tooltips were also fixed for events and tasks.
The plan for the next little while is to focus more on fixing the bugs
in the product, then try to speed things up, since calendar is still
pretty slow.
