Enhanced reportUnnecessaryComparison diagnostic check so it also detects cases where a function appears within a condition expression. This is a common source of programming error.

Added support for per-line suppression of diagnostics using # pyright: ignore comment. This also supports rule-specific suppression using a list of diagnostic rules, as in # pyright: ignore [reportGeneralTypeIssues].

Changed strictParameterNoneValue to default to true rather than false. This reflects the updated guidance in PEP 484, which indicates that type checkers should not assume that a default argument of None should imply an Optional type.

Changed the behavior of the package type verifier so it does not flag unannotated class or instance variables if a parent class provides a type annotation for a variable of the same name. The type is inherited in this case. Also updated the library guidance to reflect this change.

Document reveal_type() and reveal_locals() ( #2996 )
...
reveal_locals() was not documented anywhere, which may be part of why so few people know about it.
Happy to put this somewhere else if you prefer.

Changed import resolution order to more closely match PEP 561. Typeshed stdlib type stubs are now resolved later in the import resolution process, after all local modules and modules within the python environment.

62ac83694e
Implemented a new diagnostic check "reportMissingSuperCall" that checks for __init__, __init_subclass__, __enter__ and __exit__ methods that fail to call through to their parent class(es) methods of the same name. This is a common source of bugs. The check is disabled by default in basic mode but enabled by default in strict mode.

Changed type guard logic that involves is operator and literals to be limited to bool and enum literals. It was making unsafe assumptions for other forms of literals.

Improved type narrowing for x == L pattern to include x is L, since they are equivalent. Likewise, extended x.y == L pattern to include x.y is L.

Added support for new type narrowing pattern: len(x) == L and len(x) != L where x is a tuple or union of tuples and L is a literal integer value.

Implemented support for type guards that are based on a local variable that is assigned an expression that narrows the type of the assigned expression. Some limitations apply. For details, refer to https://github.com/microsoft/pyright/blob/main/docs/type-concepts.md#narrowing-based-on-local-variable .
