Probably when we released 1.0.0 we should have given it a SHLIB_VERSION_NUMBER OF "1.0". The last digit isn't helpful (and in fact IIRC in the forthcoming 1.1.0 release it is "1.1"). This represents the ABI version. 1.0.2 is binary compatible with 1.0.0. You should be able to drop in a 1.0.2 version of the library without having to recompile apps built for 1.0.0 (as long as we didn't accidentally break something ;-)). This only works if the compile options have remained consistent between the two library versions though. Matt
