@icebob do I need to get approval on a version bump ... or just merge it?

Looks like the bump task for npm run version automatically creates the git tag... do I do that manually, or let Travis handle it?

[icebob]

You can merge it.

I think after you run git push --tags travis detects it is a new tag and start publishing...
