~~~~~~~~~~~~~~~

- Made ``nine-venv`` recreate the virtualenv from scratch.
- Made ``local`` recreate ``node_modules`` and the virtualenv from
scratch.

~~~~~~~~~~~~~~~

- Fixed ``nine-alias-remove`` to actually remove the second subdomain.
- Added a ``--include-www`` option to ``nine-alias-add`` and
``nine-alias-remove``. The ``www.`` subdomain isn't added or removed
by default anymore.

~~~~~~~~~~~~~~~

- Removed the redundant ``--trailing-comma es5`` argument to prettier,
it is the default.
- Splitted ``_fmt_pipx_cmds`` into ``_fmt_isort`` and ``_fmt_black``.
- Reordered ``fmt`` to run Python tasks first, as ``check`` does.
- Extracted the branch check into its own ``_check_branch`` function.
- Changed ``nine-venv`` to prefer pyenv shims instead of the potentially
outdated system-provided python3 binary.

~~~~~~~~~~~~~~~

- Added our own ``entry_points`` so that the ``--include-deps`` argument
to ``pipx`` isn't necessary anymore.
- Removed an unnecessary `` noqa``.
- Stopped running ``flake8`` when formatting code.

~~~~~~~~~~~~~~~

- Added the ``--stable`` switch to ``upgrade`` to only install stable
Python packages, no alpha, beta or rc versions.
- Disabled shortflags to ``dev``.
- Changed the default ``fmt`` implementation to run isort, black and
flake8 via `pipx <https://pipxproject.github.io/pipx/>`__. It is
recommended you remove ``isort`` configuration from your project.
- Added default options when running prettier so that prettier
configuration may be dropped from package.json (ES5 commas, no
semicolons where not necessary).
- Changed ``check`` to run flake8 using pipx too.
- Inlined the ``dev`` and ``prod`` npm scripts.

~~~~~~~~~~~~~~~

- Added a multi-env example to the README.
- Switched to running all commands with ``echo`` and ``pty`` and without
``replace_env``.
- Activated rsync stats instead of succeeding silently or filling the
screen several times with spam when deploying.
