Comment 3 for bug 1714107

I strongly urge you to reconsider this. Unless others begin contributing to your fork of Python 2.7, you're probably going to miss a number of future security issues, make building and deployment more complex, and break compatibility with the Python packages Calibre depends upon.

I've started working on getting Calibre running under both Python 2 and 3. Are you open to patches provided they do not negatively impact anything?
