-INCOMPATIBLE CHANGES SINCE 2.4.x
-================================
-
-    Please take a few minutes to read the following list, especially
-    paying attention to the most important changes which are marked
-    with '!' in the first column.
-
-    Also please note that you should ensure that WXWIN_COMPATIBILITY_2_4
-    is defined to 1 if you wish to retain maximal compatibility with 2.4
-    series.
-
-! windows are no longer fully repainted when resized, use new style
-  wxFULL_REPAINT_ON_RESIZE to force this (wxNO_FULL_REPAINT_ON_RESIZE still
-  exists but doesn't do anything any more, this behaviour is default now)
-
-! wxWindow::m_font and m_backgroundColour/m_foregroundColour are no longer
-  always set, use GetFont(), GetBack/ForegroundColour() to access
-  them, and they will be dynamically determined if necessary.
-
-
-! The Sizers have had some fundamental internal changes in the 2.5.2
-  and 2.5.3 releases intended to make them do more of the "Right
-  Thing" but also be as backwards compatible as possible.  First a bit
-  about how things used to work:
-
-    * The size that a window had when Add()ed to the sizer was assumed
-      to be its minimal size, and that size would always be used by
-      default when calculating layout size and positions, and the
-      sizer itself would keep track of that minimal size.
-
-    * If the window item was Add()ed with the wxADJUST_MINSIZE flag
-      then when layout was calculated the item's GetBestSize would be
-      used to reset the minimal size that the sizer used.
-
-  The main thrust of the new Sizer changes was to make behaviour like
-  wxADJUST_MINSIZE be the default, and also to push the tracking of
-  the minimal size to the window itself (since it knows its own needs)
-  instead of having the sizer take care of it.  Consequently these
-  changes were made:
-
-    * The wxFIXED_MINSIZE flag was added to allow for the old
-      behaviour.  When this flag is used the size a window has when
-      Add()ed to the sizer will be treated as its minimal size and it
-      will not be readjusted on each layout.
-
-    * The min size stored in wxWindow and settable with SetSizeHints or
-      SetMinSize will by default be used by the sizer (if it was set)
-      as the minimal size of the sizer item.  If the minsize was not
-      set (or was only partially set) then the window's best size is
-      fetched and it is used instead of (or blended with) the minsize.
-      wxWindow:GetBestFittingSize was added to facilitate getting the
-      size to be used by the sizers.
-
-    * The best size of a window is cached so it doesn't need to
-      recalculated on every layout.  wxWindow::InvalidateBestSize was
-      added and should be called (usually just internally in control
-      methods) whenever something is done that would make the best
-      size change.
-
-    * All wxControls were changed to set the minsize to what is passed
-      to the constructor or Create method, and also to set the real
-      size of the control to the blending of the minsize and bestsize.
-      wxWindow::SetBestFittingSize was added to help with this,
-      although most controls don't need to call it directly because it
-      is called indirectly via the SetInitialSize called in the base
-      classes.
-
-  At this time, the only situation known not to work the same as
-  before is the following:
-
-    win = new SomeWidget(parent);
-    win->SetSize(SomeNonDefaultSize);
-    sizer->Add(win);
-
-  In this case the old code would have used the new size as the
-  minimum, but now the sizer will use the default size as the minimum
-  rather than the size set later.  It is an easy fix though, just move
-  the specification of the size to the constructor (assuming that
-  SomeWidget will set its minsize there like the rest of the controls
-  do) or call SetMinSize instead of SetSize.
-
-  In order to fit well with this new scheme of things, all wxControls
-  or custom controls should do the following things.  (Depending on
-  how they are used you may also want to do the same thing for
-  non-control custom windows.)
-
-    * Either override or inherit a meaningful DoGetBestSize method
-      that calculates whatever size is "best" for the control.  Once
-      that size is calculated then there should normally be a call to
-      CacheBestSize to save it for later use, unless for some reason
-      you want the best size to be recalculated on every layout.
-
-    * Any method that changes the attributes of the control such that
-      the best size will change should call InvalidateBestSize so it
-      will be recalculated the next time it is needed.
-
-    * The control's constructor and/or Create method should ensure
-      that the minsize is set to the size passed in, and that the
-      control is sized to a blending of the min size and best size.
-      This can be done by calling SetBestFittingSize.
-
-! wxURL has undergone some radical changes.
-
-    * Many accessors of wxURL - GetHostName, GetProtocolName, and GetPath,
-      have been replaced by its parent's (wxURI) counterparts - GetServer,
-      GetScheme, and GetPath, respectively.
-  
-    * ConvertToValidURI has been replaced by wxURI.  Do not use 
-      ConvertToValidURI for future applications.
-
-    * ConvertFromURI has been replaced by wxURI::Unescape.
-    
-- no initialization/cleanup can be done in wxApp/~wxApp because they are
-  now called much earlier/later than before; please move any exiting code
-  from there to wxApp::OnInit()/OnExit()
-- also, OnExit() is not called if OnInit() fails
-- finally the program exit code is OnRun() return value, not OnExit() one
-- wxTheApp can't be assigned to any longer, use wxApp::SetInstance() instead
-- wxFileType::GetIcon() returns wxIconLocation, not wxIcon
-- wxColourDatabase is not a wxList any more, use AddColour to add new colours
-- wxWindow::Clear() is now called ClearBackground()
-- pointer returned by wxFont::GetNativeFontInfo() must not be deleted now
-- wxMouseEvent::Moving() doesn't return true if mouse is being dragged any more
-- (most) controls now inherit parents colours by default, override
-  ShouldInheritColours() to return false if you don't want this to happen
-- wxApp::SendIdleEvent() now takes 2 arguments
-- wxTabView::GetLayers() changed return type from wxList& to wxTabLayerList&
-  (when WXWIN_COMPATIBILITY_2_4 == 0)
-- wxID_SEPARATOR (id used for the menu separators) value changed from -1 to -2
-- wxGetNumberFromUser() is now in separate wx/numdlg.h, not wx/textdlg.h
-- wxChoice and wxCombobox now handle their size in the same way as in all the
-  other ports under MSW, new code is actually correct but different from weird
-  stuff they were doing before so the behaviour of your programs might change
-- wxTaskBarIcon objects must now be destroyed before the application can exit.
-  Previously, the application terminated if there were no top level windows;
-  now it terminates if there are no top level windows or taskbar icons left.
-- wxZlibInputStream is not by default compatible with the output of the
-  2.4.x version of wxZlibOutputStream. However, there is a compatibility mode,
-  switched on by passing wxZLIB_24COMPATIBLE to the constructor.
-- when WXWIN_COMPATIBILITY_2_4 == 0 wxHashTable uses a new implementation
-  not using wxList keyed interface (the same used when wxUSE_STL == 1),
-  the only incompatibility being that Next() returns a wxHashTable::Node*
-  instead of a wxNode*.
-- non-const wxDC methods GetBackground(), GetBrush(), GetFont() and GetPen()
-  as well as wxWindow methods GetFont() and GetCursor() don't exist any more,
-  please fix your code -- it never worked correctly anyhow if you modified the
-  objects returned by these methods so you should simply switch to using const
-  methods.
-- wxWindow::GetFont() now returns wxFont object instead of reference
-- EVT_XXX macros are now type-safe; code that uses wrong type for event
-  handler's argument will no longer compile.
-- Identical functionality of wxFileDialog::ParseWildcard,
-  wxGenericDirCtrl::ParseFilter, Motif and MSW parsing native dialogs
-  is now accessible in ::wxParseCommonDialogsFilter
-- wxNotebookSizer and wxBookCtrlSizer are now deprecated -- they are no longer
-  needed, you can treat wxNotebook as any other control and put it directly
-  into the sizer that was wxNotebookSizer's parent sizer in old code.
-- wxFile methods now return either wxFileOffset or wxFileSize_t which may be a
-  64 bit integer type, even on 32 bit platforms, instead of off_t and so the
-  return value of wxFile::Length(), for example, shouldn't be assigned to off_t
-  variable any more (the compiler might warn you about this)
-- wxListItem::m_data is now of type wxUIntPtr, not long, for compatibility
-  with 64 bit systems
-- wxSizer::Add/Insert returns pointer to wxSizerItem just added so conditions
-  writeen with if(Add(..)==true) will not work. Use if(Add(..)) instead.
-
-
-DEPRECATED METHODS SINCE 2.4.x
-==============================
-
-Deprecated methods may still be used but will disappear in future wxWidgets
-versions, please update your code to not use them.
-
-- wxURL::GetInputStream() and similar functionality has been depreciated in 
-  favor of other ways of connecting, such as though sockets or wxFileSystem.
-- wxDocManager::GetNoHistoryFiles() renamed to GetHistoryFilesCount()
-- wxSizer::Remove(wxWindow *), use Detach() instead [it is more clear]
-- wxSizer::Set/GetOption(): use Set/GetProportion() instead

-- wxListBase::operator wxList&(): use typesafe lists instead
-- wxTheFontMapper: use wxFontMapper::Get() instead
-- wxStringHashTable: use wxHashMap instead
-- wxHashTableLong: use wxHashMap instead
-- wxArrayString::GetStringArray: use wxCArrayString or alternative wxWidgets
-                                 methods taking wxArrayString
-- wxArrayString::Remove(index, count): use RemoveAt instead
-- wxTreeItemId conversion to long is deprecated and shouldn't be used
-- wxTreeCtrl::GetFirst/NextChild() 2nd argument now has type wxTreeItemIdValue
-  and not long, please change declarations of "cookie"s in your code
-  accordingly -- otherwise your code won't work on 64 bit platforms
-- [MSW only] wxWindow::GetUseCtl3D(), GetTransparentBackground() and
-             SetTransparent() as well as wxNO_3D and wxUSER_COLOURS styles
-- wxList keyed interface: use wxHashMap instead
-- wxColourDatabase::FindColour(): use Find() instead (NB: different ret type)
-- wxHashTable::Next: use wxHashTable::Node* or
-                     wxHashTable::compatibility_iterator to store the return
-                     value
-- wxWave class; use wxSound instead
-- The wxHIDE_READONLY flag for wxFileDialog was not implemented
-  and has now been removed
