## Typechecking improvements
We've made various improvements to the Luau typechecker:
* We allow duplicate function definitions in non-strict mode.
* Better typechecking of `and`, `(f or g)()`, arrays with properties, and `string:format()`.
* Improved typechecking of infinite loops.
* Better error reporting for function type mismatch, type aliases and cyclic types.
## Performance improvements
We've made quite a few performance improvements to the Luau bytecode interpreter.
* Function calls are now faster in the common case of one- or two-argument functions.
* Some built-in operations such as equality checking and modulo arithmetic are now faster.
* Calls to `string.method()` are now faster
## Coming soon...
