### What's new
* Added lint warning for using redundant `@native` attributes on
functions inside a `--!native` module
* Improved typechecking speed in old solver for modules with large types
### New Solver
* Fixed the length type function sealing the table prematurely
* Fixed crashes caused by general table indexing expressions
### VM
* Added support for a specialized 3-argument fast-call instruction to
improve performance of `vector` constructor, `buffer` writes and a few
`bit32` methods

### What's new
* A bug in exception handling in GCC(11/12/13) on MacOS prevents our
test suite from running.
* Parser now supports leading `|` or `&` when declaring `Union` and
`Intersection` types (#1286)
* We now support parsing of attributes on functions as described in the
[rfc](https://github.com/luau-lang/rfcs/pull/30)
* With this change, expressions such as `local x = @native function(x)
return x+1 end` and `f(@native function(x) return x+1 end)` are now
valid.
* Added support for `@native` attribute - we can now force native
compilation of individual functions if the `@native` attribute is
specified before the `function` keyword (works for lambdas too).
### New Solver
* Many fixes in the new solver for crashes and instability
* Refinements now use simplification and not normalization in a specific
case of two tables
* Assume that compound assignments do not change the type of the
left-side operand
* Fix error that prevented Class Methods from being overloaded
### VM
* Updated description of Garbage Collector invariant

### New Type Solver
* Fixed crash in numeric binary operation type families
* Results of an indexing operation are now comparable to `nil` without a
false positive error
* Fixed a crash when a type that failed normalization was accessed
* Iterating on a free value now implies that it is iterable
