+which is a breaking change to AST matching code. The following matchers were
+affected:

+=======================	============================
+recordDecl		recordDecl and cxxRecordDecl
+ctorInitializer		cxxCtorInitializer
+constructorDecl		cxxConstructorDecl
+destructorDecl		cxxDestructorDecl
+methodDecl		cxxMethodDecl
+conversionDecl		cxxConversionDecl
+memberCallExpr		cxxMemberCallExpr
+constructExpr		cxxConstructExpr
+unresolvedConstructExpr	cxxUnresolvedConstructExpr
+thisExpr		cxxThisExpr
+bindTemporaryExpr	cxxBindTemporaryExpr
+newExpr			cxxNewExpr

+=======================	============================
+
+recordDecl() previously matched AST nodes of type CXXRecordDecl, but now
+matches AST nodes of type RecordDecl. If a CXXRecordDecl is required, use the
+cxxRecordDecl() matcher instead.
