A Legacy device or firmware version are a piece of hardware and/or firmware that has limited functionality in some scenarios. In our case it can be hardware or software functionality that isn't supported on the hardware or older software due to technical limitations.
What qualifies as a Legacy device or firmware is different depending on the function or feature.
For example, between major releases of Humly Control Panel and Humly Room Display firmware, new functionality can be introduced which requires the user to be on the latest version prior to the upgrade to be able to use the new functionality.
Also, since Liso Room Display can be connected and administrated through Humly Control Panel, some features that are designed for Humly Room Display in specific may not work due to hardware and software limitations on the Liso Room Display
Below are a list of functionalities that administrators need to be aware of because of Legacy limitations.
