New Feature: Added 'reportUnnecessaryIsInstance' switch. When enabled, the type checker reports any cases where isinstance() is used and the result is provably always true or false. At best, these represent unnecessary runtime overhead and more commonly represent bugs.
Enhancement: Made a bunch of suggested improvements to the type completion provider in the VS Code extension.
Enhancement: Improved responsiveness of VS Code extension, especially when files are being analyzed in the background.
Enhancement: Added unreachable code reporting after 'break' statements.
Bug Fix: Improved type constraint logic when the 'continue' keyword is used within a loop.
Bug Fix: Added support for properties whose type is defined using a generic TypeVar type.

Enhancement: Added special-case handling of `__all__` assignments so referenced symbols are marked as accessed.
Enhancement: Added support for class declarations that include base classes that are declared in terms of a variable with a "Type[X]" type annotation.
Enhancement: Changed logic in type completion provider to sort suggestions such that dunder names (magic types) appear after other names (under the assumption that the former are more rare).
Bug Fix: Fixed bug in type completion logic that prevented members from super-classes from being included in the suggestion list.
Bug Fix: Fixed missing check in type constraint logic that resulted in an "internal error" when "is" operator was used with LHS expression that included an index.
Bug Fix: Added support in type checker for dictionary expansion entries in a dictionary literal expression.

New Feature: Implemented NewType type support.
Enhancement: Improved type analyzer in case where class is passed in a context where a function is expected. The analyzer now synthesizes a function that corresponds to the class's constructor and/or init routine.
Enhancement: Added function documentation support in signature provider.
Enhancement: Made a bunch of suggested improvements to the completion provider including support for built-in types and selection details.
Bug Fix: Fixed bug in docstring processing where the entire docstring is on a single line.
Bug Fix: Fixed bug in type analyzer. It was incorrectly reporting that "yield" statements were not allowed in async functions. Only "yield from" should be flagged as errors.

New Feature: Added "strictParameterNoneValue" rule.
New Feature: Improved type checking for raise and raise/from statements.
Bug Fix: Fixed handling of super() call. It now properly handles zero, one and two-arg versions. Also handles case where target class derives from multiple base classes.

New Feature: Wildcard characters are now supported for include, exclude, ignore and strict path arrays in the config file. Supported wildcards include ** (matches against one or more directories), * (matches against zero or more characters), and ? (matches against a single character).
New Feature: Added config rule "reportCallInDefaultInitializer" that emits an error or warning when a function call is used within a parameter's default value initialization expression.

New Feature: Implemented type checking for augmented assignment statements.
New Feature: Implemented minimal support for InitVar class used in dataclass declarations.
