Luau is our new language that you can read more about at [https://roblox.github.io/luau](https://roblox.github.io/luau). It's been a busy month in Luau!

## Typed variadics
|
|
|
|
[TODO]
|
|
|
|
## Generic functions
|
|
|
|
[TODO]
|
|
|
|
## Typechecking improvements
|
|
|
|
* Check bodies of methods whose `self` has type `any`
|
|
* More precise types for `debug.*` methods
|
|
* Better typechecking for `Instance:IsA`.
|
|
|
|
## Performance improvements
|
|
|
|
* Optimized `coroutine.resume`
|
|
(a 10% speed-up in benchmarks)
|
|
* New implementation of string mutations, which mutates in place rather than copying if there's
|
|
only one copy of the string buffer (a 20% speedup)
|
|
* New `FASTCALL` specializations, optimizing common cases for methods such as `table.insert`
|
|
(a 40% speedup)
|
|
* Improved `table.move` performance (often 3x faster!)
|
|
|
|
## Library changes
|
|
|
|
* Added the `debug.info` function which allows retrieving information about stack frames or functions; similarly to `debug.getinfo` from Lua, this accepts an options string that must consist of characters `slnfa`; unlike Lua that returns a table, the function returns all requested values one after another to improve performance.

|
Luau now has a shiny new logo!

|
## Coming soon...

|
|
|
* Better treatment of cyclic requires
|
|
* [Anything else?] |
