=========================
Minor Changes
-------------
- Changed MANIFEST.in to a more specific include structure, & a
redundant exclude structure, to more confidently keep development
environment key material from being uploaded during packaging.
Major Changes
-------------
- Overhauled the ``gen_key()`` which now creates a different set of
default keys. We are no longer creating one primary key which does
certifying & signing, with one subkey which handles encryption.
Instead, we create one certifying primary key, with three subkeys,
one each for handling encryption, authentication, & signing. This
is a more theoretically secure default key setup, & represents a
common best-practice.
