1.3.x is compatible with 1.2.x in the sense that programs compiled against 1.2.x must continue to run against 1.3.x. The reverse is not true, which is why in minor version number bumps we can add new functions. To remove functions (or macros for that matter, although that's for reasons of compile time compat, not runtime) we need to bump the major version. See http://apr.apache.org/versioning.html for details. -garrett
