why different servers stable vs beta

[dennisVDM]

I noticed last night that beta players seem to have different servers than stable.

Why??

is there a way to have both?

I use stable to prevent beta-errors

Different server because different versions.

To have servers from both versions on the same DCS Version, both stable and beta need to be on the same version.

A very basic explanation is that a lot of files may be different or missing from patch to patch and that difference will cause problems. For example the Mirage F-1 and door gun on the Mi-24 are in open beta but not release branch. What does your client see when either of those are present if you join a server featuring them? The game handles it to a degree but there would be some unforeseen consequences. Thus they try to keep versions with enough changes separated. Sometimes open beta patches and it is no longer compatible with the previous open beta patch.
