Stairways Software has released version 5.3.1 of its Keyboard Maestro automation utility, which fixes an issue with executing Automator workflows in the upcoming release of OS X 10.8 Mountain Lion. This maintenance release also patches some memory leaks, resolves a performance issue with the Button Condition, provides Growl notification when a timeout cancels a macro, fixes a performance issue with getting the Finder’s selection, fixes the SECONDS() function, allows “APPLICATION” in the menu condition, and ensures that triple click actions perform correctly. The Mac App Store version of Keyboard Maestro 5.3.1 (not yet available as of this writing) now includes a fix that avoids “no autorelease pool” warnings when launching the engine. ($36 new from Stairways Software or the Mac App Store, free update, $25 upgrade from versions previous to 5.0, 17.7 MB, release notes)
