Stairways Software has released Keyboard Maestro 5.1, which brings a number of improvements and fixes to the automation utility. Most notably, the update adds a new For Each action that enables you to loop over a variety of collections (including files in a folder, mounted volumes, lines in a file, and more), acting on each item in turn. Other additions include a Percent Encode for URL filter and a signed developer ID that is used by OS X 10.8 Mountain Lion’s Gatekeeper security feature. The update also fixes a crash that could occur when a called text factory no longer exists, as well as a lockup when entering quoted strings in calculations. Read a complete rundown of all the improvements and fixes included in this update at the company’s blog. ($36 new, free update, $25 upgrade from versions previous to 5.0, 16.3 MB, release notes)
