⚠️ The first rule of upgrading: If it ain't broke, don't fix it!
In other words, ensure that there is a good reason to mess with a working installation (e.g., a need to use a new feature or address a found problem fixed in the current version).
⚠️ Danger:
If you maximum all channel at the same time, it will highly possible damage the bulb and we will not provide warranty in such case.
