 ## Next Release
 
+### Features
+
+#### CPP Rules
+
+- Add `noPublicLeadingUnderscore` AST check flagging public member variables and member functions (including static and template ones) whose name starts with `_`, e.g. `int _count;` or `void _compute();` under `public:` (or under a `struct`'s default access) should drop the leading underscore. Private/protected members are never checked here, since that's the concern of `memberLeadingUnderscore`/`memberFunctionLeadingUnderscore`. Constructors/destructors, operator overloads/conversions, and methods overriding a base-class virtual method are always exempt, and members synthesized entirely by a macro invoked on the same source line are excluded too. Takes no configuration
+- Add `classMemberOrder` AST check enforcing a fixed section order within each class/struct/union body: public, protected, then private member variables, followed by public, protected, then private member functions. Only in-class declarations count — out-of-line member-function definitions don't affect ordering — and declarations outside that list (nested types, `using` declarations, enums, friend declarations, ...) are ignored rather than resetting the sequence. Takes an optional `excluded_macros` list (e.g. `["Q_OBJECT"]`) so members/access-specifier changes synthesized by a named macro invocation are excluded from ordering entirely

+classMemberOrder
+=================
+
+Flags a member variable or member function declared before a section that
+must precede it. Within a single class/struct/union body (including
+templates), the direct members must appear grouped, in exactly this order:
+
+1. public member variables
+2. protected member variables
+3. private member variables
+4. public member functions
+5. protected member functions
+6. private member functions
+
+.. code-block:: cpp
+
+   class Widget {
+   public:
+       int size;
+
+   protected:
+       int flag;
+
+   private:
+       int count;
+
+   public:
+       void resize();
+
+   protected:
+       void hook();
+
+   private:
+       void compute();
+   };
+
+   class Bad {
+   private:
+       int count;      // Bad — flagged, a private member variable
+
+   public:
+       int size;        // before a public one.
+
+       void resize();
+
+   private:
+       void compute();
+
+   public:
+       void hook();      // Bad — flagged, a public member function after
+                          // a private one.
+   };
+
+A section may be skipped entirely (e.g. a class with no protected members
+at all), but once a later section has started, an earlier one may not
+reappear.
+
+Only members declared lexically inside the class body count — an
+out-of-line member-function definition (``void C::f() { ... }``) never
+affects its class's ordering, only the in-class declaration does. Nested
+types, ``using`` declarations, enums, friend declarations, and other
+declarations not covered by the list above are ignored for ordering
+purposes: they neither need to fit anywhere in particular nor reset the
+sequence.
+
+Configuration
+--------------
+
+Optional — exclude specific macros invoked inside a class body from
+ordering entirely. Any member (or access-specifier change) synthesized by
+a listed macro, matched by the macro's own name at its invocation line, is
+skipped: it's neither flagged itself nor counted when checking what came
+before or after it. Useful for macros such as Qt's ``Q_OBJECT`` that expand
+to boilerplate members and their own access-specifier bookkeeping, whose
+position isn't the author's choice.

+noPublicLeadingUnderscore
+===========================
+
+Flags any data member or member function declared under a ``public:``
+access specifier (or under no access specifier at all in a
+``struct``/``union``) whose name starts with ``_``. Private/protected
+members are never flagged here — that's the concern of
+:doc:`memberLeadingUnderscore <enforce_member_leading_underscore>` and
+:doc:`memberFunctionLeadingUnderscore
+<enforce_member_function_leading_underscore>`.
+
+.. code-block:: cpp
+
+   class Widget {
+   public:
+       int size;        // Good.
+       int _size;        // Bad — flagged, leading underscore on a public member.
+
+       void compute();  // Good.
+       void _compute();  // Bad — flagged, leading underscore on a public method.
+
+   private:
+       int _count;        // Good — not checked here.
+   };
+
+Constructors/destructors, operator overloads/conversions, and methods
+overriding a base-class virtual method are always exempt, since their names
+aren't the author's to change. A member synthesized entirely by a macro
+invoked on that same source line is not flagged either — there is no
+user-typed name to rename.
+
+Configuration
+--------------
