* Fix a bug where reading a property from an unsealed table caused inference to improperly infer the existence of that property. * Fix #827 We have also made a lot of progress on the new solver and the JIT. Both projects are still in the process of being built out. Neither are ready for general use yet. We are mostly working to tighten up how the new solver handles refinements and updates to unsealed tables to bring it up to the same level as the old solver. --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
