Most of the updates done to them are compatible only with the 0.9.9.0 beta, some of the minor tweaks are backwards compatible. I am still working on them anyway, they are not in a release ready state and probably won't be until 0.9.9.0 releases.
Those are currently mostly finished, but I also set them up for 0.9.9.0 so kind of in the same area as the Trek ships. I could look into finalizing and adjusting them, but I have tons of addons currently in the works and I am exceptionally lazy.
