What's Changed

  • New vector library! See https://rfcs.luau.org/vector-library.html for details
  • Replace the use of non-portable strnlen with memchr. strnlen is not part of any C or C++ standard.
  • Introduce lua_newuserdatataggedwithmetatable for faster tagged userdata creation of userdata with metatables registered with lua_setuserdatametatable

Old Solver

  • It used to be the case that a module's result type would unconditionally be inferred to be any if it imported any module that participates in any import cycle. This is now fixed.

New Solver

  • Improve inference of table.freeze: We now infer read-only properties on tables after they have been frozen.
  • We now correctly flag cases where string.format is called with 0 arguments.
  • Fix a bug in user-defined type functions where table properties could be lost if the table had a metatable
  • Reset the random number seed for each evaluation of a type function
  • We now retry subtyping arguments if it failed due to hidden variadics.
