Once again, all of our changes this week are for new type solver and the JIT. In the new type solver, we fixed cyclic type alias handling and multiple stability issues. In the JIT, our main progress was for arm64, where, after lowering 36% of instructions, we start seeing first Luau functions executing natively. For x64, we performed code cleanup and refactoring to allow for future optimizations.
