# 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 even 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
