v7.2.0 — Full Release

[apprenticeharper]

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.

I get:

traceback.print_exc()

TabError: inconsistent use of tabs and spaces in indentation

When trying to import a book from Kindle for Mac. 7.1.0 was working fine for me.

[deirdrew]

I just had to revert to 7.1.0 as it failed on one of two Amazon books I just got using Kindle for PC 1.17.1. As soon as I reverted it was successful.

[pdurrant]

It looks like there's a 7.2.1 already.

[pdurrant]

It works for me for AZW3

[deirdrew]

Just saw that (sorry, was testing 7.2.0 on a different PC that has Kindle for PC latest version and didn't see the new email). Yes, 7.2.1 was able to handle the book 7.20 could not. :)

I just saw that dedrm was working with Calibre version 5. So, I tried to install it and I received the message I've attached. It's likely I'm doing something Wrong but...
I'm in Windows 10 v. 2004 x64 and using Calibre Portable 5.17.

I see the attachment didn't work - I shall try again, else I shall type it in! I think this time it worked!

Unzip DeDRM_tools_7.2.1.zip. Load DeDRM_plugin.zip.

Hello, ElleKayEm:
Well, now I feel like a real fool! From this little demonstration, you'd never know I've only been working with computers since 1962!
Thank you - As I said, I just knew it was something I was doing wrong.
Again, thank you very much for your help!

I upgrade my widnows to windows 11 , and I found I can't import the patch
