Flexibits has issued Fantastical 2.4, a big update that adds a number of frequently requested features to the calendar app. You can now view, create, and edit attachments on iCloud and Exchange accounts (attachments can only be viewed on Google accounts), plus set and view travel time for events (which also enables time-to-leave notifications). The update can also combine identical events on multiple calendars, improves invitation support for Google Calendar and Exchange, adds full Undo and Redo support, adds an option to respond to Exchange invitations without sending a reply, and enables you to customize the number of weeks shown in month view (see more details in this Flexibits blog post). It also displays Facebook events from secret groups and shows new and updated Facebook events more quickly thanks to push updates. ($49.99 new from Flexibits and the Mac App Store, free update, 14.3 MB, release notes, 10.11+)
