I was in the process of trying to install the luasandbox Apache module, but the LUA 5.1 requirement is truly a problem, unless I'm compiling LUA myself. Even on my rather ancient server OS (a few years old), the LUA that comes with it is LUA 5.2. The latest LUA version is 5.3.4. I doubt someone will ever find a LUA 5.1 package on a current distro.
Thus my question: Is there a plan to support newer LUA versions in the future?
