   The deployment is not possible without bumping the `TinyOrm` library version number because a git tag must be created. That means that bumping only the `tom`, `TinyDrivers`, `TinyMySql`, or `TinyUtils` isn't possible. This used to be possible, but not anymore because git tags are created during deployment.
