That's why I said "technically unstable", due to the fact that "nightly" builds inherently have a risk of instability, due to their very nature.
The reality is that there's not been any changes to 10.2 HD+ branch in awhile, so really the nightly could possibly just be relabeled as stable by the maintainers, but until that occurs, it obviously retains the label of "nightly" which is considered to be an unstable release.
