### What's changed?
* Syntax for [read-only and write-only
properties](https://github.com/luau-lang/rfcs/pull/15) is now parsed,
but is not yet supported in typechecking
### New Type Solver
* `keyof` and `rawkeyof` type operators have been updated to match final
text of the [RFC](https://github.com/luau-lang/rfcs/pull/16)
* Fixed issues with cyclic type families that were generated for mutable
loop variables
### Native Code Generation
* Fixed inference for number / vector operation that caused an
unnecessary VM assist
