Highlights

• @TerryE has added Lua 5.3 alongside the Lua 5.1 support; build with make LUA=53 to build against the new language core. The new language core brings many under-the-hood improvements and we anticipate switching to Lua 5.3 by default in the next release and removing 5.1 in the release thereafter.

Please see the release milestone for all the details.
