Why is the DraftSight 2017 SP2 for Linux still a Beta version?

When I run DraftSight 2017 SP2 for Linux, I always get the Splash screen telling that it is still a Beta version. Does this mean that the latest Linux version of DraftSight has unresolved bugs and less well-developed features, compared with the Windows version of this program? Beta versions give me a feeling of being less stable than stable versions.
