+- Add wxArrayString methods to wxTextValidator and any other
+ class that needs them.
+- Add wxNotebook::GetTabRect or similar so we can estimate
+ page size better in wxNotebookBase::CalcSizeFromPage.
+- Add function to clear all wxNotebook tabs without
+ destroying the pages.
+- Add individual setters to wxScrollBar and other classes
+ that use a combined setter.
+- Remove traces of old resource system from wxWizard.
+- Have wxDirCtrl as alias for wxGenericDirCtrl.
+- Allow instant reaction to left-up in a wxGrid cell
+ (extend editor API) to work around bad checkbox
+ behaviour (click, click, click, click away...) and
+ reduce checkbox size on non-Windows platforms.
+- Add wxNotebook::HitTest for non-Windows platforms.
