2.6.4:
* Xml(const char* buffer, ) constructor: Make this actually
work. (Douglas C. MacKenzie) Bug #326512.
* Documentation: Clarified lifetime rules. (Ole Laursen)
* Build:
- Fixed build when disabling properties and exceptions.
(Armin Burgmeier, Openismus)
- Check for both m4 and M4 in the GNU m4 output, to fix
the build on some platforms. (Yselkowitz) Bug #42399.
* Glade::get_widget(): Show the name of not-found
widgets on the console, because libglade does not seem to
do this anymore (I think it did once.)
* Example: Delete the dialog when we are finished with it.
* Windows build fixes.
libglademm 2.6 is API/ABI-compatible with libglademm 2.4.
Changes since libglademm 2.4:
* Glade::Xml: Added connect_clicked() for easy connection of
buttons and menuitems signals.
* Glade::VariablesMap: now handles Entry, ComboTextEntry,
SpinButton, *Scale, Calendar and CheckBox.
