The main change over 7.0.0b4 is an update to ineptpdf.py that should allow some Adobe Digital Edition PDFs to be decrypted.
I currently only have one sample, and it works with that.
If 7.0.1 doesn't work for your PDF, but 6.8.1 does, please send me the encrypted book and your adept.der key by email to firstname.lastname@example.org
I have bumped the version number just to make tracking issues easier. This is NOT a full release. Just testing the DeDRM plugin.
