Release notes

3.0.5 (2021-08-10)

Require python 3.6+, simplified bootstrap (giving up on pex)
Major changes:
- NOT using pex any more (unfortunately there's always an issue with dependencies when using pex, like for example: click having different requirements depending on python version)
- New bootstrap script get-pickley
- pickley does not try and "bootstrap itself" anymore (used to re-install itself as a venv, from pex)
Upgrade pickley automatically as well when installing bundles
Added version-check command
