Firmware v2.8.0 User Guide ?

We have a new firmware, but I couldn’t find its detailed user manual?

2.8.0 has several different products that it runs on…
The B5/B5c, A5x and the C# line.

Each of those links will also take you to a very detailed user guide for all of the features and settings of each of those devices.
