The good news is that the disabled readers can still remove DRM which would inhibit their ability to use the content. The bad news is that there are no other exceptions which would allow you to remove the DRM.
Update: One reader pointed out that I should have read more carefully. The exceptions for disabled readers is actually broader than before. A couple restrictive clauses were removed. For example, the exception used to state that all versions of a title must have the accessibility features disabled. Now someone can strip the DRM of a legally purchased Nook ebook just because that is the one they own. It doesn't matter if the other formats are accessible.
What would have I liked to see? How about allowing us to remove DRM on dead platforms (MSReader, Microsoft, and more) or perhaps an exception on removing DRM on legally purchased content after the seller revokes access (okay, that would never be allowed to happen).
Still, at the very least I can report that the status quo has remained ante. With this Register of Copyrights, I expected to lose exceptions, not gain any. She is an industry stool pigeon after all.
