+changes relevant for those building unison from source.  We omit most
+bugfixes and minor improvements, but of course every release contains
+some.  Refer to the documentation for details; this file is a terse
+notice of changes rather than a tutorial about new features.
 
 As of 2022, this file (NEWS.md at top level) is used for news.
 
 Some software has a "changelog" file that records all changes, but
 unison uses git history for that, and thus there is no changelog file.
