# NOTE: releaselevel should be left at 'invalid' for trunk development
#     and set to 'final' for releases.  During development, the
#     major.minor.micro should point ot the NEXT release (generally, the
#     next micro release after the current release).
#
# Note: When cutting a release, also update the major/minor/micro in
#
#     pyomo/RELEASE.txt
#
# The VOTD zipbuilder will automatically change releaselevel to "VOTD
# {hash}" and set the serial number to YYMMDDhhmm.  The serial number
# should generally be left at 0, unless a downstream package is tracking
# master and needs a hard reference to "suitably new" development.
