This release DOES NOT work with calibre 5.0. Stick with calibre 4.23 for now if you need DRM removal.
This release adds full support for the new .kinf2018 key files and the nw KFX encryption. Many thanks to Apprentice Sakuya for their work on this.
This means that this release now works with the latest (2.8) version of Kindle for PC and Kindle for Mac.
A script to remove DRM from B&N PDFs has been included but not integrated into the plugin, nor tested.
