Release Notes 7.2.0

This release incorporates numerous small bug fixes contributed through pull requests to the GitHub repository. Thank you to all contributors.

It also now includes code that should handle the latest KFX encryption used by the latest Kindle for PC and Kindle for Mac. How long this code will work is anyone’s guess. It may be that Amazon will update Kindle for PC/Mac very quickly. In which case, the existing work-arounds to get KF8 format should still work.

I am very grateful to those dedicated developers who spend their free time reverse-engineering the DRM code.

Release Notes 7.2.1

I messed up some white space. I still haven’t got KFX to work for me, but I don’t think I’ve actually broken anything this time.
