# What's changed ### Debugger * Values after a 'continue' statement should not be accessible by debugger in the 'until' condition ### New Type Solver * Many fixes to crashes and hangs * Better bidirectional inference of table literal expressions ### Native Code Generation * Initial steps toward a shared code allocator --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
