25 # Pixman versioning scheme
27 # - The git version must at all times have an odd MICRO version
30 # - If you add API, increment the MICRO version to the next largest
33 # - If you release a version that contains new API, then increment
34 # MINOR and set MICRO to 0.
36 # - If you release a new version that does not contain new API, then
37 # increment MICRO to the next even number.
39 # - After doing a release, increment MICRO again to make the version
42 # - If you break the ABI, then
46 # - In the first development release where you break ABI, find
47 # all instances of "pixman-n" and change them to pixman-(n+1)
49 # This needs to be done at least in
54 # This ensures that binary incompatible versions can be installed
55 # in parallel. See http://www106.pair.com/rhp/parallel.html for
