I misunderstood how release-please computes conventional-commit breaking changes (!) with the type chore, so my merge of #201 was erroneous. I have recreated the PR here. @pham sorry. The reason for the change of conventional-commit type was because this change is breaking, so the initial fix: would only create a semver patch update, not a semver minor update, fix!: would create a semver minor update.

Thanks for the merge @jthegedus! Appreciate the work you're doing!
