+ * `A7-1-1` - no longer report parameters as contravening this rule. This is inline with the rule intent as described in the referenced C++ Core Guidelines rule [CON.1](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#con1-by-default-make-objects-immutable), which states "To avoid confusion and lots of false positives, don’t enforce this rule for function parameters."

+- `A3-9-1` - `VariableWidthIntegerTypesUsed.ql`:
+    - Exclude the plain char type. Still includes `signed char` and `unsigned char`.
+    - Include CV-qualified variable width integer types.
+- `A3-9-1` - `VariableWidthPlainCharTypeUsed.ql`:
+    - New query to support fine grained deviation support for the plain char type.
