OmniFocus 2.3 adds a new layout option for the outline and fixes bugs in OS X El Capitan.

• "Custom Columns” Layout — A new Layout pane has been added to OmniFocus Preferences. Fluid Layout is the one you’ve been using since OmniFocus 2 shipped. In Custom Columns layout, horizontal space is redistributed automatically between the columns as you resize the window, with columns whose entries are likely to be shorter staying close together. Customers with Pro can choose which layout to use per perspective via the View popover in the toolbar. For more information, check out OmniFocus Help > Preferences > Layout.
• Title Folding — Use Show Full Item Title > When Selected in the View menu to only show the first line of items’ titles and keep rows vertically compact. Item titles are automatically expanded to show the full title when you select a row.
• Sync Log — Sync Preferences now includes a sync log (in Show Sync Details).
• Note Buttons — Both Fluid and Custom Columns layout use a new note button. If an item has a note, the chevron on its note button indicates the action that OmniFocus will take when you click the button. Clicking a note button with a downward pointing chevron expands the note. Clicking a note button with an upward pointing chevron collapses it.
• Status Circles — The indicator for repeating tasks looks more like small, repeating status circles now (and less like the elipsis button in apps like iTunes and Music).
• El Capitan — Fixed bugs and visual glitches in OS X El Capitan.
• Sync Conflict — Fixed a bogus sync conflict resulting in the error message “Unable to synchronize database with server; The local database appears to have been reset and is no longer able to reach transaction identifiers”
• Attachment Window — Greatly improved performance when deleting a large number of attachments.
• Documentation — Updated the docs for new features and generally improved them.
• Smaller Fixes and Improvements — A great number of bugs have been fixed as part of implementing the new layout options.

OmniFocus 2.2.5 fixes crashes:

• Sidebar Crash — Fixed a crash changing selection in the sidebar—our most common remaining crash in OmniFocus 2.2.x
• Crash — Fixed a crash related to pruning old OmniFocus backups.

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.
