Releasing ramp workflow

• Update the changelog:

  • Change the "Unreleased" to the new version, and add a new empty unreleased section
  • Make just this change in a single commit: eg git commit -m "Release 0.2.0"
  • Example commit: https://github.com/paris-saclay-cds/ramp-workflow/commit/167db887b48fa48646f02bebc36499641c14c342
  • Push this commit to master, or more safely: go through the PR process

• Tag this commit on master with the new version number:

  • Make sure you updated your local master branch (after the steps above)
  • Make sure you are on the release commit from above (check with git log)
  • Tag that commit: eg git tag -a v0.2.0 -m "Version 0.2.0"
  • Push this commit to github: git push --tag

That's all. Now a new release will be available on github and rampwf.__version__ will indicated the new version number.

(TODO: we should update this with how to upload to PyPI once we do this)
