• Fixed: GetOptions on external member throws AssertionFailedException.

• Fixed: Contracts: Default direction of inherited contracts with default directions may be interpreted incorrectly on the implementation site.
• Fixed: ContractAspect.Direction does not contain enough context to be implemented as an option.
• Fixed: ICompileTimeSerializable: Manual serializers not being consumed by derived classes.
• Fixed: MetalamaCompileTimePackage is ignored.
• Fixed: Calls to undefined methods lead to pointless dependency analysis warnings.
• Fixed: Aspect tests do not await non-async and non-Task main methods.
• Fixed: Local function inside compile-time if produces error.
• Fixed: Type property of ExpressionFactory.Capture output is always "object".
• Fixed: IConditionallyInheritable.IsInheritable does not receive enough context to be implemented as an option.
