+- added wxToolBar Add/InsertTool(tool) (Janusz Piwowarski)
+- WXR resources can now be used in Unicode builds
+- it is now possible to use several wxFileHistory objects in the same menu
+ by giving them different base IDs (Dimitri Schoolwerth)
+
+- changed to type-safe wxSizerItemList for wxSizer child items
+ Deprecated:
+ wxSizer::Remove( wxWindow* )
+ - it does not function as Remove would usually be expected to
+ and destroy the window, use Detach instead
+ wxSizer::GetOption(),
+ wxSizer::SetOption()
+ - wxSizer 'option' parameter was renamed 'proportion' to better
+ reflect its action, use Get/SetProportion instead
+ wxKeyEvent::KeyCode()
+ - use GetKeyCode instead
+ wxList:: Number, First, Last, Nth
+ - use typesafe GetCount, GetFirst, GetLast, Item instead
+ wxNode:: Next, Previous, Data
+ - use typesafe Get* instead
+ wxListBase::operator wxList&()
+ - use typesafe lists instead
