Flexibits has revved Fantastical 2 for Mac (http://flexibits.com/fantastical) to version 2.2. It costs $49.99 and requires Mac OS X Yosemite or El Capitan.

The app lets you create, view, and search events and reminders. In version 2.2 m account syncing is now native, enabling features such as invitation responses, availability lookup, categories, and people lookup. Fantastical 2’s native CalDAV engine also lets users connect directly to other calendar services such as iCloud, Google, and Yahoo.

Fantastical also now supports availability with a user interface letting users easily and quickly check their colleagues’ availability. Availability requires a supporting calendar service, such as Exchange, Google Apps, or OS X Server. Some of the other new features in 2.2 include printing (with multiple, beautiful layouts), a second time zone time line (to let you quickly view other time zones), multiple selection (to move and delete multiple items at once), and the ability to start the week or month views on the current day or week.
