The main reason for this update is the addition of support for Lua 5.2, which we will want to import sometime. Released on 2013/06/14. * Issue 1: Added support for Lua 5.2 while maintaining support for Lua 5.1. Applications using Lutok can be modified to use the new interface in this new version and thus support both Lua releases. However, because of incompatible changes to the Lua API, this release of Lutok is incompatible with previous releases as well. * Issue 3: Tweaked configure to look for Lua using the pkg-config names lua-5.2 and lua-5.1. These are the names used by FreeBSD. Interface changes: * New global constants: registry_index. * New methods added to the state class: get_global_table. * Removed global constants: globals_index.
