I'm pretty sure he means the new implementation of the ACW in BIAB 2018 for Windows, where it is now an integral part of the main program.
Built-in Audio Chord Wizard
The Audio Chord Wizard has been redesigned and is now built into Band-in-a-Box®. Previously, the Audio Chord Wizard was a separate app and not tightly integrated into Band-in-a-Box®. This app is still available from the (Audio Chord Wizard) toolbar button, but the improved built-in Audio Chord Wizard can be accessed from the Audio Edit Window.
