Tag builds not triggered despite all workflow jobs configured for it

EDIT (and answer): include version: 2.1 at the very top instead of 2.0

My set up is as below:

config.yml:

workflows:
  version: 2
  standard-workflow:
    jobs:
      - build:
          filters:
            tags:
              only: /.*/
      - push:
          requires:
            - build
          filters:
            tags:
              only: /.*/
            branches:
              ignore: /.*/

commands:

git commit -am 'some commit'
git tag 0.3.0
git push --tags

However, there is no reaction from CircleCI, and tags are not built

Just to be clear does that work, or are you still having a problem?
