West version 0.6.0rc1 has been tagged. Release notes are in this pull request:
Testing and feedback are welcome; I’d like this to be the minimum version for Zephyr 2.0. To install this RC, use “pip3 install west==0.6.0rc1” (and pip3 install --user on Linux as usual).
You can “pip3 uninstall west” then “pip3 install west” (without the version specifier) to go back to v0.5.8.
