Incompatible Changes
- Special blocks (e.g. BEGIN) are called in void context
- Unoverloaded stringification of regular expression does not return the expression literal
- T_DATAUNIT and T_CALLBACK XS typemaps removed
- User defined case-changing has been removed in favor of Unicode::Casing
- XSUB C functions are static now and they are not exported from their object files
- Read-only references cannot be weaken

Clojure joined by leiningen and tools
Fedora 18 now ships a more complete Clojure programming stack, including the build tool Leiningen. This will make it easier to package other Clojure libraries in the future.
