Changes to the Script Extension property in 16.0 that aren't documented in the release notes

[Karl Williamson]

I got a complaint from the field that U+02C7 is unexpectedly listed as 
in the Latin script in 16.0

Someone investigated and the only changes listed for that property are 
that the ScriptExtensions.txt file has been re-ordered.

I checked, and they are correct.  I then looked at a difference listing 
between the 15.1 and 16.0 versions, and there are extensive changes 
beyond reordering.

Is there something we're missing, or did the 16.0 changes list omit 
these things?
