Auto-deploy on merge to master?

[marctorsoc]

I see that the config is

deploy:
  provider: pypi
  user: pyncha
  password:
    secure: ****
  on:
    tags: true
    python: 3.9

so it doesn't auto-release https://pypi.org/project/pandavro/#history. Not being an expert in travis, it looks to me like it will only release a new version once you manually add a tag to a branch, as explained in https://docs.travis-ci.com/user/deployment/pypi/#deploying-tags. Wouldn't be easier just to release every time you merge on master? i.e:

  on:
    branch: master

as explained here: https://docs.travis-ci.com/user/deployment/pypi/#deploying-specific-branches

WDYT?
