Do you have any reason to upgrade to 5.5?

Many people still use 5.1 because that is already a complete language that works fine. Most people don't really need the new features. Plus if you stay on 5.1 you get compatibility with LuaJit and Luau so much better performance.

There are nice new features in recent updates, but so far our strategy has been to stick to the version we use.
