BusyMac has released BusyCal 2.6.6 with a number of improvements and fixes for the calendar app. The update adds a Copy BusyCal Event URL to Clipboard command, as well as Smart Filter predicates for “is set” and “is not set.” It also adds support for matching tags in the Attendee and Contact fields from BusyContacts and auto-filling field members (requires the just-released BusyContacts 1.0.3). BusyCal 2.6.6 improves Quick Entry, improves speed when dismissing hundreds of notifications, fixes an issue that prevented alarms from going off when snoozed past midnight, and adds a Simplified Chinese localization. ($49.99 new from BusyMac or the Mac App Store (version 2.6.6 available soon), free update, 10.3 MB, release notes, 10.9+)
