13# This is the "Release" of the Libevent ABI.  It takes precedence over
14# the VERSION_INFO, so that two versions of Libevent with the same
15# "Release" are never binary-compatible.
16#

18# will increment for each series until we revise our interfaces enough

23# This is the version info for the libevent binary API.  It has three
24# numbers:
25#   Current  -- the number of the binary API that we're implementing
26#   Revision -- which iteration of the implementation of the binary
27#               API are we supplying?
28#   Age      -- How many previous binary API versions do we also
29#               support?
30#
31# To increment a VERSION_INFO (current:revision:age):
32#    If the ABI didn't change:
33#        Return (current:revision+1:age)
34#    If the ABI changed, but it's backward-compatible:
35#        Return (current+1:0:age+1)
36#    If the ABI changed and it isn't backward-compatible:
37#        Return (current+1:0:0)
38#
39# Once an RC is out, DO NOT MAKE ANY ABI-BREAKING CHANGES IN THAT SERIES
40# UNLESS YOU REALLY REALLY HAVE TO.

80# ABI version history for this package effectively restarts every time
81# we change RELEASE.  Version 1.4.x had RELEASE of 1.4.
82#
83# Ideally, we would not be using RELEASE at all; instead we could just
84# use the VERSION_INFO field to label our backward-incompatible ABI
85# changes, and those would be few and far between.  Unfortunately,
86# Libevent still exposes far too many volatile structures in its
87# headers, so we pretty much have to assume that most development
88# series will break ABI compatibility.  For now, it's simplest just to
89# keep incrementing the RELEASE between series and resetting VERSION_INFO.
90#
91# Eventually, when we get to the point where the structures in the
92# headers are all non-changing (or not there at all!), we can shift to
93# a more normal worldview where backward-incompatible ABI changes are
94# nice and rare.  For the next couple of years, though, 'struct event'
95# is user-visible, and so we can pretty much guarantee that release
96# series won't be binary-compatible.
