Instant On has been updated to version 5.0.1, with full support for capturing audio from sandboxed applications from the Mac App Store and other sources. This update also fixes a very rare startup issue.

Audio Hijack Pro can now capture all System Audio, as well as grab audio from already-running applications, on Mac OS X 10.7 (Lion). This is accomplished with Instant On 4.1, which can be installed through the "Install Extras" window, under the Audio Hijack Pro menu.
Specific improvements have been made for capturing audio from Spotify and QuickTime Player
AppleScripts which are triggered when a recording finishes now run on their own thread instead of in their own process. Script users should test their scripts to ensure they still function as expected.

Sessions now correctly remember if they were set to use the "Multi-Process" hijacker.
