# This is the point release for libevent.  It shouldn't include any
# a/b/c/d/e notations.
RELEASE = 1.4

# This is the version info for the libevent binary API.  It has three
# numbers:
#   Current  -- the number of the binary API that we're implementing
#   Revision -- which iteration of the implementation of the binary
#               API are we supplying?
#   Age      -- How many previous binary API versions do we also
#               support?
#
# If we release a new version that does not change the binary API,
# increment Revision.
#
# If we release a new version that changes the binary API, but does
# not break programs compiled against the old binary API, increment
# Current and Age.  Set Revision to 0, since this is the first
# implementation of the new API.
#
# Otherwise, we're changing the binary API and breaking bakward
# compatibility with old binaries.  Increment Current.  Set Age to 0,
# since we're backward compatible with no previous APIs.  Set Revision
# to 0 too.
VERSION_INFO = 4:0:2

###
# History:
#   We started using Libtool around version 1.0d.  For all versions from
#   1.0d through 1.3e, we set RELEASE to the version name, and
#   VERSION_INFO to something haphazard.  The didn't matter, since
#   setting RELEASE meant that no version of Libevent was treated as
#   binary-compatible with any other version.
#
#   As of 1.4.0-beta, we set RELEASE to "1.4", so that releases in the
#   1.4.x series could be potentially binary-compatible with one another,
#   but not with any other series.  (They aren't.)  We didn't necessarily
#   set VERSION_INFO correctly, or update it as often as we should have.
#   The VERSION_INFO values were:
#    1.4.0-beta .. 1.4.4-stable     : 2:0:0   [See note 1]
#    1.4.5-stable                   : 3:0:1   (compatible ABI change)
#    1.4.6-stable                   : 3:1:1   (no ABI change)
#    1.4.7-stable                   : 3:1:1   [see note 1]
#    1.4.8-stable                   : 3:2:1   (no ABI change)
#    1.4.9-stable                   : 3:2:1   [see note 1]
#    1.4.10-stable                  : 3:3:1   (no ABI change)
#    1.4.11-stable .. 1.4.13-stable : 3:3:1   [see note 1]
#    1.4.14a-stable:                : 3:3:2   [see note 2]
#    1.4.14b-stable:                : 4:0:2   (compatible ABI change)
#
# [1]: Using the same VERSION_INFO value was wrong; we should have been
#      updating the Revision field.
# [2]: We set the VERSION_INFO completely wrong on 1.4.14b-stable
