I haven't yet updated Calibre to 2.22.0, but version 2.21 told me about
the new version the last time I ran it, and offered to update it for me.

This raises a few problems:

* It's automatically phoning home on launch without my consent, which is
  a breach of privacy.

* I don't know exactly what would happen if I let it attempt to update
  itself, but since upstream Calibre includes non-free software (unrar),
  it's probably offering to install non-free software for me.

We should disable this functionality in our Calibre package.
