   This happens if channel.id is not set, and channel.parent does not have a name either
 - `Pulse.axis_angle` is now in radians instead of degrees.
 - Channel offsets (e.g. `SingleChannel.opx_output_offset`) is None by default (see note in Fixed)
+- `Pulse.id` is now an instance variable instead of a class variable
 
 ### Fixed
 - Don't raise instantiation error when required_type is not a class
