- Fixed a logic error which caused ``--deploy --system`` to overwrite editable vcs packages in the pipfile before installing, which caused any installation to fail by default.  `2417 <https://github.com/pypa/pipenv/issues/2417>`_

- Updated requirementslib to fix an issue with properly quoting markers in VCS requirements.  `2419 <https://github.com/pypa/pipenv/issues/2419>`_

- Added support for python 3.7 via a few small compatibility / bugfixes.  `2427 <https://github.com/pypa/pipenv/issues/2427>`_

- Using the ``python -m pipenv.help`` command will now use proper encoding for the host filesystem to avoid encoding issues.  `2466 <https://github.com/pypa/pipenv/issues/2466>`_
