I looks like calibre is out of date again. (3.38 vs 3.40.1).
I am willing to help keep this updated if that would be helpful. Would this be as simple as updating the binaries with the newest versions, updating the ini files for versions and re-running the installer to build the package?
Is there anything else I should know?
