I develop a piece of software and then there is an update and for example like with the update from tody JSON is handled in a complete new (not better) way. The currently developed code isn´t woking any more (can not deployed to the devices). Now I need to change all the parts in the software where JSON is handled. I can select a specific firmware in the burner BUT not in the UI flow side. There is only a switch v1.4.5, v1 latest and v2 latest.

This is not what I would expect from an reliable development environment, where I have an configuration/version/release management.
