# These functions load, manipulate and store the current version information
# for OpenSSL 3.0 and on.
# They are meant to be minimalistic for easy refactoring depending on OpenSSL
# version.
#
# Version information is stored in the following variables:
#
# |MAJOR|, |MINOR|, |PATCH| are the three parts of a version number.
# |MAJOR| is to be increased for new major releases, |MINOR| for new
# minor releases, and |PATCH| for update releases.
#
# |SERIES| tells what release series the current version belongs to, and
# is composed from |MAJOR| and |MINOR|.
# |VERSION| tells what the current version is, and is composed from |MAJOR|,
# |MINOR| and |PATCH|.
# |TYPE| tells what state the source is in. It may have an empty value
# for released source, or 'dev' for "in development".
# |PRE_LABEL| may be "alpha" or "beta" to signify an ongoing series of
# alpha or beta releases. |PRE_NUM| is a pre-release counter for the
# alpha and beta release series, but isn't necessarily strictly tied
# to the prerelease label.
#
# Scripts loading this file are not allowed to manipulate these
# variables directly. They must use functions such as fixup_version()
# below, or next_release_state(), found in release-state-fn.sh.
# These functions depend on |SOURCEDIR|, which must have the intended
# OpenSSL source directory as value.
