 - Fixed a crash when traverse lambda expr with invalid captures. (#GH106444)
 
+- Fixed ``isInstantiated`` and ``isInTemplateInstantiation`` to also match for variable templates. (#GH110666)
+
 - Ensure ``hasName`` matches template specializations across inline namespaces,
   making `matchesNodeFullSlow` and `matchesNodeFullFast` consistent.
