Hi, Karl
Someone should have provided a response sooner. First, the re-ordering of data in ScriptExtensions.txt actually was done in Unicode 16.0. See https://www.unicode.org/reports/tr44/tr44-34.html#Change_History. Regarding the entry for 02C7, the script extension was changed from {Common} in 15.1 (by virtue of no entry, hence defaulting to its Script property) to {Latin, Bopomofo} in 16.0. That was part of a set of additions to ScriptExtensions.txt that UTC had approved at UTC #178 (January 2024) — see consensus 178-C39: https://www.unicode.org/L2/L2024/24006.htm#178-C39 The change was committed into the file within the following month, and would have been visible in public review no later than the Unicode 16.0 Beta.

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?
