# 2.0.2-alpha -- 2:0:0
|

# 2.0.3-alpha -- 2:0:0 (should have incremented; didn't.)

# 2.0.5-beta -- 4:0:0
|
|
# Planned:
|
|
# 2.0.6-rc -- 2.0 2:0:0
|
|
# 2.0.7-stable -- 2.0 2:1:0 (Assuming no ABI change)
|

|
|
# If Libevent 2.1.1 makes 'struct event' etc opaque in the headers:
|
|
# 2.1.1-alpha -- 2.x 1:0:0

# 2.1.1-alpha -- 2.1 1:0:0

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