* main: Changed the evaluated type of `__class__` from `type[Self]` to `type[<Enclosing class]`. This addresses #10685. (#10874) Added optimization that reduces the number of Uri objects that need to be created during type evaluation. This is an attempt to address #10832. (#10872) Fixed bug that causes a false negative when using unquoted types in a TypedDict functional class definition if the types are forward declared. This addresses #10612. (#10869) Fixed bug that resulted in false negative when backslash followed by line feed occurs at end of file. This addresses #10814. (#10867) Fixed false negative when a keyword parameter in a child class method overrides a method with a `**kwargs` in the parent and the type is incompatible. This addresses #10815. (#10866) Fixed regression introduced in 1.1.343 that results in nondeterministic (order-dependent) type evaluation under certain circumstances involving recursive type aliases. This addresses #10850. (#10865) Revert "Added support for tracking multiple constraint sets when performing protocol matching. This allows protocols with overloaded methods to contribute independent constraint sets. This addresses #9835. (#9864)" (#10863) Fixed bug that contributes to out-of-memory crashes under certain circumstances where a module's transitive import graph is very large and may not fit within the available heap space. (#10862) Bump tmp from 0.2.3 to 0.2.5 in /packages/vscode-pyright (#10824) Added support for `match_args` dataclass parameter. This addresses #10858. (#10861) Fixed bug that results in false negative when a `closed=False` is used in `TypedDict` that subclasses from a non-open `TypedDict` base class. This addresses #10859. (#10860) Revert "Reverted a recent change that appears to have affected performance on some projects. This attempts to address #10832. (#10841)" Improved performance of import resolution when there are large number… (#10855) Document editable installs with uv (#10854) Fixed a bug that results in spurious errors if a class decorator is a… (#10846) Fixed a bug that results in false positive errors when using `object` methods (like `__eq__`) on a `Sentinel` instance. This addresses #10773. (#10844) Fixed bug that results in incorrect literal math results for bitwise negation. This addresses #10834. (#10842) Reverted a recent change that appears to have affected performance on some projects. This attempts to address #10832. (#10841) pull-pylance-with-pyright-1.1.403-20250820-201137 (#10831)
