+By way of final note, the first stable release of GHex 4 will likely be
+"4.x.0", with "x" being the contemporary GNOME release target. Eg, 4.43.0
+would be the recommended release to couple with GNOME 43.

+As GHex is part of the GNOME Extra Apps family, it is not mandatory for it to
+follow the naming convention of its major version number matching the GNOME
+release.  Since it also includes a library, libgtkhex-4, the "4.x" major
+version number is meaningful, and I would rather keep it in place.
