1.2.0

Note that this release makes the new install format (and thus new installer or an alternative supported install method) a hard requirement.

Additionally, Poetry 1.1 installed using get-poetry.py will be not be able to update using poetry self update.

See the 1.2.0 release announcement for a summary of how to migrate to install.python-poetry.org if you fall into one of these two cases.
