The only thing that looks suspicious to me is the error around 'czm_textureCube' (first and last specs). Were you seeing that error in any previous releases?

Not that I can recall and I don't see it recorded in an issue.

Seem to be tests that need updates. OK to proceed with release, but keep this open to document the test.
