The folks at Cultured Code have crossed releasing Things 1.4.5 off their to-do list. New to the task-management utility is support for the Things URI scheme, which was previously offered only in the Things iOS apps. The Task Modification Date is now available by AppleScript. Among the numerous bugs fixed are an issue where items could reorder themselves after syncing, an issue where marking items complete from within search results would bounce you to the Inbox, issues with grouping and sorting of tasks and projects, various issues with recurring tasks, and a crash under Mac OS X 10.4.
