I'm so relieved to see more types being added to good languages.

So Teal is to Lua as TypeScript is to JavaScript. Which means it automatically plays well with any Lua environment. Unlike luau and nelua which are also statically typed but have their own runtimes.

What version of Lua does it use? Lua gets new versions every few years so I don't know why so many impls don't continuously upgrade to the latest version.

Teal currenly supports generating code for Lua 5.1 and up, including LuaJIT. There are compiler flags --gen-target and --gen-compat which control various specifics of code generation.
