   the Ethereum foundation github in November 2017 and renamed to
   ``eth-utils``. The PyPi package was also renamed from
   ``ethereum-utils`` to \`eth-utils\`.

Or you can install ``tox`` to run the full test suite.

Releasing
~~~~~~~~~

To release a new version:

.. code:: sh

   make release bump=$$VERSION_PART_TO_BUMP$$

How to bumpversion
^^^^^^^^^^^^^^^^^^

The version format for this repo is ``{major}.{minor}.{patch}`` for
stable, and ``{major}.{minor}.{patch}-{stage}.{devnum}`` for unstable
(``stage`` can be alpha or beta).

To issue the next version in line, specify which part to bump, like
``make release bump=minor`` or ``make release bump=devnum``.

If you are in a beta version, ``make release bump=stage`` will switch to
a stable.

To issue an unstable version when the current version is stable, specify
the new version explicitly, like
``make release bump="--new-version 4.0.0-alpha.1 devnum"``
