Bug Fix: Fixed bug in command-line version that caused an error to be reported when "useLibraryCodeForTypes" or "verboseOutput" was specified in the pyrightconfig.json file.
Enhancement: Added support for protocol matching where the protocol includes an overloaded method.
Enhancement: Improved diagnostic messages for function type mismatches.
Enhancement: Improved diagnostic messages for tuple matching and union assignments.
Enhancement: Changed nested diagnostic messages to use non-breaking spaces so indentations are visible within the VS Code "Problems" panel.
Bug Fix: Fixed bug in reportIncompatibleMethodOverride diagnostic check. The logic was checking for wider parameter types when it should have been checking for narrower.
Bug Fix: Fixed bug in method override validation code. It wasn't applying partial specialization of the base class, resulting in inappropriate errors in some cases.
Bug Fix: Fixed bug in the type evaluation of expressions with + or - operators and integer literal operands. These expressions should evaluate to a literal type, not an int.
Bug Fix: Fixed bug in parsing of f-strings that contain \N escape and a Unicode character name that includes a hyphen.
Bug Fix: Fixed bug in type evaluator that caused an incorrect error when a class decorator was used for a generic class.
Bug Fix: (From Pylance) Fixed performance problem related to file change events triggered by reads from site-packages.
Enhancement: Enabled support for PEP 613 (TypeAlias).
Bug Fix: Fixed bug that caused type aliases to get expanded in some contexts when they shouldn't.
Bug Fix: Fixed bug that caused "from .A import *" to work incorrectly when the wildcard included symbol A.
Enhancement: Added logic in completion provider to return class variables in base classes when the insertion point is in the context of a subclass body.
Bug Fix: Fixed TypeAlias code to check for Python 3.10 rather than 3.9 since PEP 613 has been moved out to 3.10.
Enhancement: Added performance optimization for TypedDict classes. Entries are now computed once and cached in the class type. This provides a big speed-up for TypeDict classes that have a large number of fields.
Enhancement: Added performance optimization for union types that contain large numbers of string literals. The code for inserting new items into a union is O(n^2); this optimization makes it O(n) for string literal types.
Bug Fix: Fixed bug that caused custom import aliases of "Final", "Literal" and "TypeAlias" to not work correctly.
Bug Fix: Fixed bug that resulted in spurious errors when hovering over module names in import statements.
Bug Fix: Fixed several bugs relating to symbols introduced into a class by its metaclass.
Bug Fix: Fixed bug that caused type analyzer to crash when a nonlocal binding referred to a symbol that was not present in an outer scope and then was assigned to.
