• Fixed bug that leads to a false positive in the reportUnnecessaryComparison check when one operand's type is a callable and the other is not. This addresses Types object and Callable are reported to not have any overlap. microsoft/pyright#10253. (Fixed bug that leads to a false positive in the `reportUnnecessaryCom… microsoft/pyright#10267)
• Extended the check for isinstance and issubclass argument validation to flag the Literal special form, which leads to a runtime error when used in the second argument.

(Extended the check for isinstance and issubclass argument validat… microsoft/pyright#10265)
• Fixed bug that results in a false negative when a return statement contains a call expression that invokes a NoReturn call and the argument list contains errors. This addresses if no argument os._exit() comes after return, pyright doesn't notice us microsoft/pyright#10260. (Fixed bug that results in a false negative when a return statement co… microsoft/pyright#10264)
• Fixed bug that results in an incorrect error under certain circumstances when inferring the return type of a recursive function that has a decorator or is async.

(Fixed a bug that results in a false negative when the specialization … microsoft/pyright#10220)
• Extended reportUnknownVariableType check to include cases where a value whose type is a generic class parameterized by Unknown is assigned to a variable with a declared type. This addresses Disallowing casting Unknown in variable definition in strict mode microsoft/pyright#10214. (Extended reportUnknownVariableType check to include cases where a v… microsoft/pyright#10217)
