 - Fix a bug where clang doesn't automatically apply the ``[[gsl::Owner]]`` or
   ``[[gsl::Pointer]]`` to STL explicit template specialization decls. (#GH109442)
+- Introduced a new function attribute ``__attribute__((debug_transparent))``
+  which is intended as a hint to debuggers that they should not stop at the annotated
+  function, but instead step through it when stepping in, and continuing directly to 
+  its caller when stepping out.

+The ``debug_transparent`` attribute is intended as a hint for debuggers that this 
+function itself is not interesting, but it calls a function that might be.  So, when 
+stepping in arrives at a function with this attribute, debuggers should transparently 
+step-in through it into the functions called by the annotated function (but not by 
+subsequent calls made by those functions), stopping at the first one its normal rules 
+for whether to stop says to stop at - or stepping out again if none qualify. Also, when 
+stepping out arrives at a function with this attribute, the debugger should continue 
+stepping out to its caller. This attribute is currently only supported by DWARF.
+
+For example:
+
+.. code-block:: c
+
+  int bar(void) {
+    return 42;
+  }
+
+  __attribute__((debug_transparent))
+  int foo(void) {
+    return bar();
+  }
+
+  int caller(void) {
+    return foo();
+  }
+
+Stepping into ``foo`` should step directly into ``bar`` instead, and stepping out of ``bar`` 
+should stop in ``caller``.
+
+Functions with the ``debug_transparent`` attribute can be chained together:
+
+.. code-block:: c
+
+  int baz(void) {
+    return 42;
+  }
+
+  __attribute__((debug_transparent))
+  int bar(void) {
+    return baz();
+  }
+
+  __attribute__((debug_transparent))
+  int foo(void) {
+    return bar();
+  }
+  
+  int caller(void) {
+    return foo();
+  }
+
+In this example, stepping into ``foo`` should step directly into ``baz``, and stepping out of 
+``baz`` should stop in ``caller``.
