vegorov-rbx 68cdcc4a3a Sync to upstream/release/677 (#1872) ... # What's Changed? This week comes with many improvements to the new type solver and an important fix to the garbage collection to make it more robust in memory constrained scenarios. # Runtime - Garbage collection will no longer run out of memory itself, which could have happened when resizing arrays to a smaller size # New Type Solver - Type refinements on external types should now work and should no longer normalize the type into `never` - Improved error reporting when `string.format` is used with a dynamic format string - Updated type signature of `getmetatable` library function to use the corresponding type function and produce better type inference - Restored a type mismatch error when converting function types with different number of generic parameters, like `() -> ()` into `<T>() -> ()` - Types resulting from compound assignments have been simplified, reducing cyclic type introduction and inference failures - Fixed function generic types leaking into tables during bidirectional type inference (Fixes #1808 and #1821 ) - Stability and performance improvements (Fixes #1860 ) # Internal Contributors Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Ariel Weiss <aaronweiss@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Sora Kanosue <skanosue@roblox.com> Co-authored-by: Varun Saini <vsaini@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>		2025-06-06 11:52:47 -07:00
