0.6.0

Deprecated APIs

• Some unused predicates in SsaDefinitions.qll, TObject.qll, protocols.qll, and the pointsto/ folder have been deprecated.
• Some classes/modules with upper-case acronyms in their name have been renamed to follow our style-guide. The old name still exists as a deprecated alias.

Minor Analysis Improvements

• Changed CallNode.getArgByName such that it has results for keyword arguments given after a dictionary unpacking argument, as the bar=2 argument in func(foo=1, **kwargs, bar=2).
• getStarArg member-predicate on Call and CallNode has been changed for calls that have multiple *args arguments (for example func(42, *my_args, *other_args)): Instead of producing no results, it will always have a result for the first such *args argument.
• Reads of global/non-local variables (without annotations) inside functions defined on classes now works properly in the case where the class had an attribute defined with the same name as the non-local variable.

Bug Fixes

• Fixed an issue in the taint tracking analysis where implicit reads were not allowed by default in sinks or additional taint steps that used flow states.
