Version 2.1.1 provides over 40 minor bug fixes and performance tweaks, including enhanced support for 32-bit Audio Unit Bridge plug-ins, improved stability when changing or removing audio devices, and the resolution of a bug that caused audio output loss when the user enabled "Display audio engine overload" messages. The update also improves screen controls in several areas, increases the reliability of number keys acting as command triggers, and restores proper behavior to several aspects of the Loopback plug-in. The lengthy release notes are available in a Knowledge Base article on Apple's Web site. The hefty update is available via Software Update and Apple's Support Downloads page. (Free, 207 MB)
