+- Update to version 2.99.6:
+  + signal:
+    - Remove slots() and the container that it returns, and the
+      iterator for that container.
+    - connect(): Return a connection, instead of an iterator that
+      can be implicitly converted to a connection.
+  + Use std::shared_ptr<> for signal_impl reference-counting.
+    Instead of manual reference-counting (bgo#764935).
+  + slot: Use unique_ptr<> to avoid direct call of destructor
+    (bgo#764935).
+  + Add optional benchmark code, using boost::timer.
+  + Make some single-item constructors explicit.
+  + Make some member variables and methods private.
+  + Remove _ and __ prefixes on variables and parameters.
+  + Header guards: Remove leading underscores (and trailing
+    underscores).
+  + limit_derived_target<T_Target>: Rename to
+    limit_trackable_target<> and visit_each_type<T_Type>() to
+    visit_each_trackable() to make their purpose more obvious.
