Wrt to the updates: Does it mean it maintains the original environment variables you passed in separate from the ones set by the container? E.g. when updating a container with watchtower: You deploy a container 'python-something'. The container has PYTHON=3.11. Now, the container has an update which sets PYTHON=3.13. Watchtower will take the current settings, and use them as the settings to be preserved. So the next version will deploy with PYTHON=3.11, even though you haven't set those settings.
