3.0.0 (unstable): Gtk: * Change all operator void* to operator const void*, with a BoolExpr typedef and extra documentation. This avoids an unintentional implicit cast to int, and is generally considered good practice in C++. The new C++ standard allows the use of the explicit keyword here instead, but that is not yet widespread. (Murray Cumming, Daniel Elstner) * NumerableIcon: Really add get_background_gicon() const. (Murray Cumming, Kjell Ahlstedt) * StateFlags: Added missing STATE_FLAG_NORMAL enum value. (Kalev Lember)
