Version: 4.1 beta2 (using 4.00.82 (KDE 4.0.82 >= 20080610), Debian packages) Compiler: cc OS: Linux (i686) release 2.6.25-2-686 It used to be possible to select kaddressbook as an additional calendar resource, so birthdays and anniversaries would show up in the calendar, but this is not possible anymore.
I set the birthdays in the addressbook resource and I see the birthdays in agendaview. But, you are correct that I don't see them in the new month view.
That's a problem with recurring events in the new month view. They currently only show up on the very first occurrence (the real birthdays in this case). That issue is being worked on, and should be solved soonish.
Has been fixed with a commit from yesterday. Sorry, I didn't CC the commit to this bug... Please test again with the current svn version, and reopen if there is still a problem.
