Behavior Change: Changed encoding of diagnostics reported through the LSP interface. The diagnostic rule (if applicable) is now reported in the "code" field, and a URL points to general documentation for diagnostic rules.
Enhancement: Added support for type arg lists specified in a tuple expression (like Dict[(str, str)]) which is a legal way of writing type annotations.
Bug Fix: Fixed infinite recursion due to a __call__ method that returns an instance of the class that is being called.
Bug Fix: Fixed bug that caused completion suggestions not to work for member accesses when the LHS of the expression was a type specified in the form Type[X].
Bug Fix: Fixed bug that resulted in an attempt to parse and bind a native library (binary file) resulting in long latencies and out-of-memory errors.
Enhancement: Improved error message for unknown named parameters for TypeVar constructor.
Bug Fix: Fixed recent regression that causes a crash in certain circumstances when binding a method to an object or class in cases where that method doesn't have a "self" parameter but instead just has *args and **kwargs parameters.
Bug Fix: Fixed bug that resulted in incorrect reporting of unreported variables or parameters when they are accessed within argument expressions in cases where an error is detected when analyzing a call expression.
Enhancement: Expand ${env:HOME} in settings. Thanks to @ashb for the contribution.
Bug Fix: Fixed bug that generated incorrect errors when a callable type included another callable type as an input parameter and the second callable type had generic parameter types.
Bug Fix: Fixed bug that caused a false negative when a default parameter value was assigned to a parameter with a generic type annotation.
Bug Fix: Fixed bug that caused incorrect error to be reported when applying logical operators ("|", "&" or not) to enum.Flag literals.
