1.4.0

New Features

• A getTemplateClass predicate was added to the DeductionGuide class to get the class template for which the deduction guide is a guide.
• An isExplicit predicate was added to the Function class that determines whether the function was declared as explicit.
• A getExplicitExpr predicate was added to the Function class that yields the constant boolean expression (if any) that conditionally determines whether the function is explicit.
• A isDestroyingDeleteDeallocation predicate was added to the NewOrNewArrayExpr and DeleteOrDeleteArrayExpr classes to indicate whether the deallocation function is a destroying delete.

Minor Analysis Improvements

• The controlling expression of a constexpr if is now always recognized as an unevaluated expression.
• Improved performance of alias analysis of large function bodies. In rare cases, alerts that depend on alias analysis of large function bodies may be affected.
• A UsingEnumDeclarationEntry class has been added for C++ using enum declarations. As part of this, synthesized UsingDeclarationEntrys are no longer emitted for individual enumerators of the referenced enumeration.
