# What's Changed? - Code refactoring with a new clang-format - More bug fixes / test case fixes in the new solver ## New Solver - More precise telemetry collection of `any` types - Simplification of two completely disjoint tables combines them into a single table that inherits all properties / indexers - Refining a `never & <anything>` does not produce type family types nor constraints - Silence "inference failed to complete" error when it is the only error reported --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Dibri Nsofor <dnsofor@roblox.com> Co-authored-by: Jeremy Yoo <jyoo@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
