# libmodbus package version number, (as distinct from shared library version)
# An odd micro number indicates in-progress development from Git
# An even micro number indicates a released version
#
# Making a point release:
# - increase libmodbus_version_micro to the next even number
#
# After the release:
# - increase libmodbus_version_minor to the next odd number
#
# Take care to update the libtool versioning when required (LIBMODBUS_LD_*).
