About libsigc++
===============

libsigc++ implements a typesafe callback system for standard C++. It
allows you to define signals and to connect those signals to any
callback function, either global or a member function, regardless of
whether it is static or virtual.

libsigc++ is also used by glibmm and gtkmm to wrap Glib and GTK+
signals.

News
====

* signal: Remove slots() and the container that it returns,
  and the iterator for that container.
  See https://mail.gnome.org/archives/libsigc-list/2016-April/msg00009.html
* signal: 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.
  (Murray Cumming) Bug #764935
* slot: Use unique_ptr<> to avoid direct call of destructor.

  (Murray Cumming)
* 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.
