# 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. # New Solver * 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: https://github.com/luau-lang/rfcs/pull/18). --- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
