I think given the frustration of users from the preview, beta and now the general release about the removal of functions and sparse information about which may still be under development, I think it would be a good idea for Evernote to publish a full roadmap to show which features are coming and a list of those that have been removed for good.
I don't think this would even need dates, just a list of features with a guide as to In Development | Coming Later | Removed Permanently and to show where the new client is going.
I think this would give users a clear indication of what to expect
