release of v6.0 that changes the protocol they could still read thanks to
Hiram Yaeger. Flarm is now entering the business of online tracking,
apparently, and the first thing to do is get back monopoly on the data
transmission, just to be sure.
There is no other reason to change the protocol and not keep it backward
compatible.


There IS another reason: privacy. Those OGN-Guys could track everyone without a working opt-out. That caused a lot of furore, especially in Germany.
