+This release is a **mandatory upgrade for the release of Elite Dangerous 
+Odyssey**.  Any bug reports against earlier releases, pertaining to Odyssey or
+not, will be directed to reproduce them with 5.0.0 or later.  There are also
+minor bugs in 4.2.7 and earlier that have been fixed in this version.  There
+will **NOT** be another 4.2.x release.
+
+The major version has been incremented not for Odyssey support, but because 
+we have made some minor breaking changes to the APIs we provide for plugin 
+developers.
