*** libsigc++ 2.0:
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 used by gtkmm to wrap the GTK+ signal system. It does not depend
on GTK or gtkmm.
libsigc++ 2.0 uses modern C++ mechanisms to achieve a highly flexible,
yet typesafe callback system. It supports all features of libsigc++ 1.2
and improves upon it with a simpler and more powerful API.
This version of libsigc++ needs GNU g++ 3.2 or higher to compile.
*** ChangeLog summary:
2.0.6:
* Fixed a memory leak in sigc::slot.
* Fixed compilation for gcc-3.4.
* Fixed compilation for Intel C++ compiler (upgraded libtool).
* Fixed project files for MSVC .Net (Timothy M. Shead).
* Fixed segfaults when compiled with MSVC .Net 2003 (moved
all calls to new and delete into non-inline library code).
* In the compatibility module use correct bound_mem_functor
variants for const (volatile) methods when creating a slot.
* Minor documentation fix.
* Resolved bugs: #152327 #148744 #152323 #151404 #153143
2.0.5:
* Distribute pregenerated configuration header for MSVC .Net.

* Fixed warnings and compiler errors in the test cases.
* Added a new test case (Murray Cumming).
* Fixed 'hello_world' example.
* Don't test optional features that fail with the Sun FORTE.
* Fixes for the Sun FORTE to compile out-of-the-box
(Damien Carbery, Murray Cumming, Martin Schulze).
* Fixes for MSVC to build a DLL out-of-the-box (James Lin).
* Improved compiler specific configuration during 'configure'.
* Added rmp description file libsigc++-2.0.spec (Eric Bourque).

* Test emission of unconnected signals in the test case.
* Suppress compiler warning at dynamic_cast<>-test for good.
(Help from Christof Petig and Timothy M. Shead.)
2.0.2:
* Suppress compiler warning in compatibility module at
dynamic_cast<>-test (fix suggested by Timothy M. Shead).
* If a custom accumulator is specified invoke it on signal
emission even if the signal's slot list is empty. (This used
to be the case in libsigc++-1.2 as pointed out by Timothy.)
2.0.1:
* Fixed serious bug in reference counting in sigc::signal_base::impl().
* Fixed SigC::Object-derivation check in SigC::slot() compatibility module.
* Fixed compilation on Apple gcc 3.3 (assisted by Spundun Bhatt).

* Added more documentation (Martin Schulze).
1.9.16:
* Fixed compiler warning in sigc::connection (Alexander Nedotsukov, Murray Cumming).
* Fixed examples and made them part of the regular build (Murray Cumming).
* Added header sigc++config.h for configure time checks (Murray Cumming).
* Added configure time checks to determine the correct syntax
for explicit template method specializations (Murray Cumming).
* Removed code using partial specializations of overloaded template methods
from test cases. SUN Forte doesn't support this feature (Martin Schulze).

* Fixed compiler warning in signal.h (Murray Cumming).
1.9.13:
* Fixed passing references through sigc::slot (Reported by Jeff Franks).
* Enabled binding of objects to method slots through sigc::bind().
* Reworked sigc::bind() API: Made the template argument for the
parameter position zero-based and optional. Added overloads for
binding of up to 7 arguments at a time when no position is specified.
* Reworked sigc::hide() API: Made the template argument for the
parameter position zero-based and optional.
* Fixed compilation problems with MSVC .Net 2003 (Roel Vanhout).
* Distribute MSVC .Net 2003 project files in the tarballs.
* Improved and extended documentation.
* Minor cleanups.
1.9.12:
* Added adaptor retype(). With this final API addition all adaptors
are in place that are available in libsigc++-1.2.
* Added negation lambda operator. Use STL names for lambda actions.
* Remove formerly disabled support for gcc extension typeof().
* Added project files for MS Visual Studio .Net 2003. (Roel Vanhout)
* Make libsigc++2 compile with .Net 2003. (Roel Vanhout, Martin Schulze)
* Build shared version of libsigc++2 by default. (Cedric Gustin)
* Add support for win32 platform. (Cedric Gustin)
* Install .m4 files. (requested by Ron Steinke)
* Cleaned up functors.
* Restructured and completed documentation of the core library parts.
1.9.11:
API Additions and important bug fixes:
* Compatibility module completed. libsigc++-1.2 filenames are preserved.
* Fixed critical bug in auto-disconnection: don't defer detaching
of a slot from all referred trackables during signal emission.
* Reduced size of slots significantly.
* Fixed support for sigc::ref() in adaptors.
* Fixed sigc::visit_each(): only hit targets that are passed by
reference; pass bound members in bound_member_functor by reference.
* Add lambda actions sigc::{reinterpret,static,dynamic}_cast_
to support explicit parameter conversion.
* Add adaptors sigc::retype_return<>() and sigc::hide_return().
Minor fixes:

* Remove compiler check for the gcc extension typeof().
* Simplify bind_functor templates.
* Move definition of struct nil into functor_trait.h.
1.9.9:
* Add a constructor to sigc::connection that takes a slot_base&
to support user defined slot lists like they are used in gtkmm.
* Fix compiler issues with gcc-3.3.2 (reported by Jeff Franks).
1.9.8:
* Add compatibility module that defines namespace SigC.
namespace SigC should be API compatible to libsigc++-1.2.
Currently only the core parts of the library are supported.
Adaptors are still to follow.
* Fix connection::operator=(). Include connection.h in sigc++.h.
* Get rid of namespace functor.

* Fixed issues with gcc-3.3. (Adreas Rottmann)
* Removed unnecessary void specializations.
* Made adaptors' operator()() (overload with no arguments) return a value.
* Made visit_each() support adaptors.
* Overhauled return type deduction to make it work without typeof().
* Added convinience macros SIGC_FUNCTORS_HAVE_RESULT_TYPE and
SIGC_FUNCTOR_TRAIT(T_functor, T_result) to make return type deduction system
support 3rd-party funtors.
* Changed syntax of group adaptor from "[functor] % grp([lambdas])" to "group
([functor], [lambdas])".
* Made many fixes to lambda functionality.
* Added var() and constant() lambda creators.
* Added many lambda operators.
* Added ref() which creates a reference wrapper to enable storage of
references in bind and group adaptors.
* Expanded test suite.
* Added documentation. (Corrections by Murray Cumming)
1.9.6:
* First public release of the unstable 2.0 generation.
libsigc++ 2.0 uses modern C++ mechanisms to achieve a highly
flexible, yet typesafe callback system. It supports all features of
libsigc++ 1.2 and improves upon it by:
- No need to specify the number of arguments in signal definitions.
- Connection of any compatible (=implicitly convertable) functor
to a signal.
- Implicit type conversions of parameters during signal emission.
- Lambda adaptor for complete restructuring of functor parameter
lists in one line (subject to changes).
- Signal has a fully featured stl style list interface.
- A convinient accumulator API (replacing the old marshaller API).
- Removal of unnecessary memory management functionality.
- Lightweight class "trackable" for use as base class of your
class hierarchy replaces class "Object".
