It looks like Beta version already uses mavlink 1.0.4.0 while master uses 1.0.2.0
So if i develop my plugin with 1.0.4.0 than it doesn’t work when i test it with master, if i develop with 1.0.2.0 it doesn’t work with beta.
Maybe i am doing som e mistakes here but shouldn’t master using at least what is in beta and not behind it?
