What's Changed

General

• All code has been re-formatted by clang-format; this is not mechanically enforced, so Luau may go out-of-sync over the course of the year.
• Remove Ast dependency on CLI.Lib by @vegorov-rbx in #1571
• Refactor CLI structure to match the include/src split that our other projects have. by @aatxe in #1573
• Implement support for math.lerp by @zeux in #1608

New Solver

• Fix negation type 'inner' method in user-defined type functions by @vegorov-rbx in #1582
• Track free types interior to a block of code on Scope, which should reduce the number of free types that remain un-generalized after type checking is complete (e.g.: less errors like 'a <: number is incompatible with number).

Autocomplete

• Fragment autocomplete now does not provide suggestions within comments (matching non-fragment autocomplete behavior).
• Autocomplete now respects iteration and recursion limits (some hangs will now early exit with a "unification too complex error," some crashes will now become internal complier exceptions).

Runtime

• Add a limit to how many Luau codegen slot nodes addresses can be in use at the same time (fixes #1605, fixes #1558).
• Added constant folding for vector arithmetic (fixes #1553).
• Added support for buffer.readbits and buffer.writebits (see: luau-lang/rfcs#18).
