25 # Pixman versioning scheme
27 # - The version in git has an odd MICRO version number
29 # - Released versions both development and stable have an even MICRO
32 # - Released development versions have an odd MINOR number
34 # - Released stable versions have an event MINOR number
36 # - Versions that break ABI must have a new MAJOR number
38 # - If you break the ABI, then at least this must be done:
42 # - In the first development release where you break ABI, find
43 # all instances of "pixman-n" and change them to pixman-(n+1)
45 # This needs to be done at least in
50 # This ensures that binary incompatible versions can be installed
51 # in parallel. See http://www106.pair.com/rhp/parallel.html for
