Rogue Amoeba has released Airfoil 4.5.7, a minor update to its popular network audio streaming app for the Mac. Most notably, the new version adds support for Mac OS X 10.7 Lion to the Instant On component, which helps capture both system audio and audio from already-active applications. It also fixes several bugs and memory leaks, including one that prevented AppleScript scripts using the System Audio device from working. ($25 new, free update, 11.4 MB, release notes)
