AC_PREREQ([2.57]) # Pixman versioning scheme # # - The git version must at all times have an odd MICRO version # number. # # - If you add API, increment the MICRO version to the next largest # odd number. # # - If you release a version that contains new API, then increment # MINOR and set MICRO to 0. # # - If you release a new version that does not contain new API, then # increment MICRO to the next even number. # # - After doing a release, increment MICRO again to make the version # number in git odd. # # - If you break the ABI, then # # - 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.
