NOTE: version 0.4.3 changes layout of pb_msgdesc_t. It requires recompiling .pb.c files and
thus breaks ABI compatibility. In general, ABI compatibility is not currently maintained
between any nanopb versions.
NOTE: There was an apparent false positive virus identification by Windows Defender of the
PyInstaller 3.6 based Windows package The package was replaced
by with rebuilt PyInstaller 4.0, which seems to avoid the problem.
Actual nanopb code is unchanged between the packages.
