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 #
17 # This number incremented once for the 2.0 release candidate, and
18 # will increment for each series until we revise our interfaces enough
19 # that we can seriously expect ABI compatibility between series.

21 RELEASE = -release 2.0

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.

64
65
66 # ABI version history for this package effectively restarts every time
67 # we change RELEASE.  Version 1.4.x had RELEASE of 1.4.
68 #
69 # Ideally, we would not be using RELEASE at all; instead we could just
70 # use the VERSION_INFO field to label our backward-incompatible ABI
71 # changes, and those would be few and far between.  Unfortunately,
72 # Libevent still exposes far too many volatile structures in its
73 # headers, so we pretty much have to assume that most development
74 # series will break ABI compatibility.  For now, it's simplest just to
75 # keep incrementing the RELEASE between series and resetting VERSION_INFO.
76 #
77 # Eventually, when we get to the point where the structures in the
78 # headers are all non-changing (or not there at all!), we can shift to
79 # a more normal worldview where backward-incompatible ABI changes are
80 # nice and rare.  For the next couple of years, though, 'struct event'
81 # is user-visible, and so we can pretty much guarantee that release
82 # series won't be binary-compatible.
