+INCOMPATIBLE CHANGES SINCE 2.2.x
+================================
+
+wxBase:
+
+- wxArray<T>::Remove(size_t) has been removed to fix compilation problems
+ under 64 bit architectures, please replace it with RemoveAt() in your
+ code.
+
+- wxArray<T> macros have been changed to fix runtime problems under 64 bit
+ architectures and as a side effect of this WX_DEFINE_ARRAY() can only be
+ used now for the pointer types, WX_DEFINE_ARRAY_INT should be used for the
+ arrays containing non-pointers.
+
+- wxObject::CopyObject() and Clone() methods were removed because they
+ simply don't make sense for all objects
+
+- wxEvent now has a pure virtual Clone() method which must be implemented
+ by all derived classes, if you have user-defined event classes please
+ add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them
+
+- wxCondition now must be used with a mutex, please read the (updated) class
+ documentation for details and revise your code accordingly: this change was
+ unfortunately needed as the old class didn't behave correctly in all cases
+
+- small change to wxStopWatch::Pause() semantics, please see the documentation
+
+- unlikely but possible incompatibility: the definition of TRUE has changed
+ from "1" to "(bool)1" (and the same thing for FALSE), so the code which
+ could be erroneously compiled previously such as doing "return FALSE" from
+ a function returning a pointer would stop compiling now (but this change
+ is not supposed to have any effects on valid code)
+
+All (GUI):
+
+- the event type constants are not constants any more but are dynamically
+ allocated during run-time which means that they can't be used as case labels
+ in the switch()es, you must rewrite them to use if()s instead
+
+ You may also define WXWIN_COMPATIBILITY_EVENT_TYPES to get the old behaviour
+ but this is strongly discouraged, please consider changing your codei
+ instead!
+
+- wxDialog does not derive from wxPanel any longer - if you were using it in
+ your code, please update it. The quick fix for the most cases is to replace
+ the occurences of wxPanel with wxWindow.
+
+- wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
+ have changed (to fix some unfortunate clashes), please check your code to
+ ensure that no tests for wxYES or wxNO are broken: for example, the following
+ will *NOT* work any longer:
+
+ if ( flags & wxYES_NO )
+ ... do something ...
+ if ( flags & wxYES )
+ ... do something else ...
+
+- wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow
+
+- wxGridCellAttrProvider class API changed, you will need to update your code
+ if you derived any classes from it
+
+- wxImage::ComputeHistogram()'s signature changed to
+ unsigned long ComputeHistogram(wxImageHistogram&) const
+
+- wxEvtHandler cannot be copied/assigned any longer - this never worked but
+ now it results in compile-time error instead of run-time crashes
+
+- WXK_NUMLOCK and WXK_SCROLL keys no longer result in EVT_CHAR() events,
+ they only generate EVT_KEY_DOWN/UP() ones
+
+- the dialogs use wxApp::GetTopWindow() as the parent implicitly if the
+ parent specified is NULL, use wxDIALOG_NO_PARENT style to prevent this
+ from happening
+
+
+wxMSW:
+
+- build system changed: setup.h is not a static file in include/wx any more
+ but is created as part of the build process under lib/<toolkit>/wx/include
+ where <toolkit> is of the form (msw|univ)[dll][u][d]. You'll need to update
+ the include path in your make/project files appropriately. Furthermore,
+ xpm.lib is no longer used by wxMSW, it was superseded by the wxXPMDecoder
+ class. You'll need to remove all references to xpm.lib from your
+ make/project files.
+
+- child frames appear in the taskbar by default now, use wxFRAME_NO_TASKBAR
+ style to avoid it, wxFRAME_FLOAT_ON_PARENT style is now obsolete and has no
+ effect
+
+- all overloads of wxDC::SetClippingRegion() combine the given region with the
+ previously selected one instead of replacing it
+
+- wxGetHomeDir() uses HOME environment variable and if it is set will not
+ return the programs directory any longer but its value (this function has
+ never been meant to return the programs directory anyhow)
+
+- wxHTML apps don't need to include wx/html/msw/wxhtml.rc in resources file
+ anymore. The file was removed from wxMSW
+
+
+Unix ports:
+
+- You should use `wx-config --cxxflags` in your makefiles instead of
+ `wx-config --cflags` for compiling C++ files. CXXFLAGS contains CFLAGS
+ and the compiler flags for C++ files only, CFLAGS should still be used
+ to compile pure C files.
+
