I have released V5.0.0.3. See
post 31 above for details.
If you use CC templates I recommend that you enable the new option in CC / Settings / Filenames / Replace existing book files before you download any books using the wireless connection.
I hope that this will the last release for a while. I want to give people a chance simply to use the new version. In addition, I will be away-from-keyboard Monday through Wed.
