3.1.0

Deprecated APIs

• The TemplateParameter class, representing C++ type template parameters has been deprecated. Use TypeTemplateParameter instead.

New Features

• New classes SizeofPackExprOperator and SizeofPackTypeOperator were introduced, which represent the C++ sizeof... operator taking expressions and type arguments, respectively.
• A new class TemplateTemplateParameterInstantiation was introduced, which represents instantiations of template template parameters.
• A new predicate getAnInstantiation was added to the TemplateTemplateParameter class, which yields instantiations of template template parameters.
• The getTemplateArgumentType and getTemplateArgumentValue predicates of the Declaration class now also yield template arguments of template template parameters.
• A new class NonTypeTemplateParameter was introduced, which represents C++ non-type template parameters.
• A new class TemplateParameterBase was introduced, which represents C++ non-type template parameters, type template parameters, and template template parameters.

Minor Analysis Improvements

• The Guards library (semmle.code.cpp.controlflow.Guards) has been improved to recognize more guard conditions.
