On the (recently introduced) 500m vertical range limitation for FLARM
signals:

Previously the ability to show traffic beyond 500m vertical was a undocumented, unreliable ‘bug’ which could have caused problems with other functions, which is why we removed it.

As this capability is not needed for collision avoidance functionality, it is not a high priority to be implemented properly, but it is definitely on our list.

Highest priority for us is an official IGC/ENL v3.0 release with all the PCAS detection and other improvements we have implemented over the last months.

A Beta version of this should become available within a week; public release before the end of April.
