# ^^^^^^^^^^^
# Package Version
#
# MAJOR.MINOR.PATCH[-PRE][+META]
#
# * increment MAJOR and set MINOR=0 and PATCH=0 for incompatible ABI/API changes (changed/removed API elements)
# * increment MINOR and set PATCH=0 for compatible ABI/API changes (added API elements)
# * increment PATCH and set PRE=-pre.0 immediately after every release, always
# * increment PRE at free will
# * for a release, set PRE="", i.e. the version number should look like "2.32.42" or maybe "2.23.42+autotools"
# * everything appended after "+" is considered build/variant metadata is not part of version ordering
# For details, see <https://semver.org/spec/v2.0.0.html>.

#
# Libtool version-info (used to determine soname)
#
# * increment REVISION immediately after every release, always
# * increment CURRENT when the next release contains any ABI changes (added/changed/removed API elements), and set REVISION=0
# * increment AGE when the next release stays compatible with the previous release (only added API elements)
# * set AGE=0 when the next release is incompatible with the previous release (changed/removed API elements)
# For details, see <https://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html>.
