We waited a year after the release of libpng 1.4 to update to it in MacPorts, and we still encountered lots of ports that were incompatible with it and needed to be patched. These patches are fairly easy but still a nuisance.
I hear libpng 1.5 drops some deprecated APIs, and I fear we're going to have even more ports that are using those. Do we have any idea how easy it will be to patch that? Should we perhaps wait awhile before updating to 1.5, in the hope that some upstream developers might fix some of these issues already?
