CFFI 0.11.0 has been on Feb 25th, 2013, but I only finished writing the release notes today, which can be consulted at https://github.com/cffi/cffi/wiki/NEWS. My development focus for the next version will be on polishing the support for aggregate values (structs, arrays, etc), hopefully making sure the concept is well defined and consistently well support in various contexts (function calling, pointer referencing, struct slots, etc.).
