OmniFocus 2.2.1 fixes bugs and adds Push Triggering for OmniFocus sync, which is coming to OmniFocus for iOS and OmniFocus for iPhone in version 2.6 (currently in TestFlight):

• Sync Triggering — If you have TestFlight builds of OmniFocus 2.6 for iOS installed, you should start seeing background syncs triggered by your Mac after installing this build. Even if you sync with your own WebDAV server, this feature changes the amount of (anonymous) data that reaches Omni servers; check out this support article for more information. If you’d like to turn off sync triggering in this build, click here.

• Sync Preferences — Updated the Synchronization Preference pane, adding a section for Push (behind Show Sync Details). Currently that section only contains a switch for opting out of push triggering.

• Unavailable Items — Reverted the change in OmniFocus 2.2 which counted unavailable items in “Due Soon”.

• Crash Deleting Attachment — Fixed a crash deleting custom perspective icons from the attachments window.

• Crash with Experimental Layout — Fixed a crash on launch when using the experimental vertically compact layout.

• Find — You can now open the Find window in non-English locales.

• Dock Badges — Prevented the Dock Badge count from going stale while OmniFocus was open but not active.

• Row Layout — Fixed a bug that made rows too tall when Text Size was set to Small in OmniFocus Preferences.

• Today Preferences — The Reset button on the Notifications Preference Pane now resets “Show In Today” along with the other items in the pane.

• Today Extension — Items deferred until today and due tomorrow no longer appear when the extension is set to show items “Due Today”.

• Crash Importing — Fixed a crash importing .oo3 files with Metadata columns.

OmniFocus 2.2 adds customization to the Today Extension and fixes several bugs, including crashes.

• Today Extension — You can now customize OmniFocus’ Notification Center Widget! Pro Customers can choose a Custom Perspective, and all customers can choose between Overdue, Due Today, Deferred Until Today, Flagged, and Inbox. Note: We are still working to resolve an issue where the Today Extension can get “stuck”; unfortunately you may be more likely to experience this when using longer lists such as custom perspectives. This forum thread includes instructions for getting around the problem temporarily.
• Idle Sync Interval — Added some fuzziness to the interval at which OmniFocus syncs while idle to prevent traffic spikes on the Omni Sync Server. This only affects customers who have not changed the default, and will make syncs more frequent but not less frequent.
• Badges — Unavailable items are now included in badge counts. We are working to get badge counts consistent across all platforms within the next few releases.
• Completion Cells — Fixed a problem where the app would hang after clicking into completion cells in Quick Entry.
• Crash in Today — Fixed a crash completing items in the Today Extension.
• Crash in Undo — Fixed several cases where Undo and Redo could cause a crash.
• Crash Unfocusing — Fixed a crash when unfocusing.
• Crash in Review — Fixed a crash opening a Perspective in second window after opening Review.
• Sidebar Crash — Fixed a crash having to do with sidebar tabs.
• Crash in Perspectives — Fixed a crash removing project sidebar selection from a ‘don’t use project hierarchy’ perspective.
• Preferences — Updated the Preference Pane Toolbar Icons
• Help — Made many updates to the OmniFocus Help.
