In case you were wondering, based on
my last posting on the subject...I'm okay with the new edition as a whole.
The Klingon map, I'm told, has had its name translations into
thlingan Hol spruced up with help from
Discovery Klingon translator Lieven Litaer, and has also been updated to note some of the systems whose existence was revealed in the first season of DSC, right along with the UFP quadrant-level and history maps. Most of the new DSC-related data points' placement makes sense overall. The rectifications of omissions from TOS, we can probably debate.
But that "Binary Stars"/Gamma Hydrae question still nags at me. I actually started fiddling with
Gaia Sky to try to find a system close enough - "six lightyears" or two parsecs from γ Hyd - to fit the dialogue as written and performed on-air. Nothing so far, but a lot of stars in that GAIA DR2 database, even a truncated download.
