# Pixman versioning scheme
#
# - The version in git has an odd MICRO version number
#
# - Released versions both development and stable have an even MICRO
# version number
#
# - Released development versions have an odd MINOR number
#
# - Released stable versions have an event MINOR number
#
# - Versions that break ABI must have a new MAJOR number
#
# - If you break the ABI, then at least this must be done:
#
# - increment MAJOR
#
# - In the first development release where you break ABI, find
# all instances of "pixman-n" and change them to pixman-(n+1)
#
# This needs to be done at least in
# configure.ac
# all Makefile.am's
# pixman-n.pc.in
#
# This ensures that binary incompatible versions can be installed
# in parallel. See http://www106.pair.com/rhp/parallel.html for
# more information
