 -------------------------------------------------------------------------------
 
-INCOMPATIBLE CHANGES SINCE 2.6.x
+INCOMPATIBLE CHANGES SINCE 2.8.x
 ================================
 
 Changes in behaviour not resulting in compilation errors, please read this!
 ---------------------------------------------------------------------------
 
-- For all wxInputStreams, Eof() becomes true after an attempt has been made
-  to read _past_ the end of file.
-- wxFileName::DirExists() checks if the path of the file is a directory, not
-  if the whole name is a directory.
-- wxDialog::CreateButtonSizer() may return NULL now, please see the manual.
-- wxStaticBoxSizer now deletes the associated wxStaticBox when it is deleted.
-- wxArray::Alloc() now works as reserve() and does not clear the array any more
-- Windows calling CaptureMouse() are now required to handle the
-  wxEVT_MOUSE_CAPTURE_LOST event and not call ReleaseMouse() in this case.
-- wxInputStream::GetC() now returns an int in the range 0 - 255 on success
-  instead of a char the range -128 - 127.

 Changes in behaviour which may result in compilation errors
 -----------------------------------------------------------
 
-- Some classes (notably wxBitmap and wxImage) don't define operator==() as it
+Deprecated methods and their replacements
-  used to work in somewhat unexpected way as it compared only internal pointers
+-----------------------------------------
-  and not the object data. The code using it will have to be updated:
-  * If the object was compared with wxNullXXX, use IsOk() method instead
-  * If valid object need to be compared, use IsSameAs() to reproduce the old
-    behaviour or change the code to avoid comparing bitmaps &c.
-- wxFontData::GetColour() now returns a const colour.
-- wxDC objects can't be created directly now (this never worked, now it doesn't
-  even compile).
-- wxCHECK family of macros now must be followed by a semicolon.
-- wxMBConv::cMB2WC() and cWC2MB() take size of the input buffer and return
-  length of the converted string in all cases now.
-- wxHtmlWindow::OnCellClicked() now returns bool.
-- wxHtmlCell::OnMouseClick() was deprecated and replaced with
-  wxHtmlCell::ProcessMouseClick(); old code overriding OnMouseClick() will
-  continue to work with WXWIN_COMPATIBILITY_2_6, but should be rewritten to
-  use ProcessMouseClick().
-- wxHtmlCell::GetCursor() was deprecated and replaced with
-  wxHtmlCell::GetMouseCursor(); old code overriding GetCursor() will
-  continue to work with WXWIN_COMPATIBILITY_2_6, but should be rewritten to
-  use GetMouseCursor().
-- wxHtmlCell::AdjustPagebreak() signature has changed, update your code if you
-  override it.
-- wxFontEnumerator::GetFacenames() and GetEncodings() now return arrays and
-  not pointers to arrays.
-- SetDefaultItem() method was moved from wxPanel to wxTopLevelWindow
-- wxDialog::OnOK/OnCancel() don't exist any more, use SetAffirmative/EscapeId()
-- wxPathList doesn't derive from (deprecated) wxStringList any more
-- wxGLContext class has no 1:1 coupling to a wxGLCanvas class any more.
-  As a consequence, the class interface changed largely. Code updates, if
-  any are required at all, are easy to accomplish though.

-- wxWindowBase::GetBestFittingSize --> wxWindowBase::GetEffectiveMinSize.
-- wxWindowBase::SetBestFittingSize --> wxWindowBase::SetInitialSize.
-- Seeking on a zip stream returned from wxFileSystem without using the new
-  wxFS_SEEKABLE flags is deprecated. You can still seek, but use the flag.
-- Constructor wxZipInputStream(const wxString& archive, const wxString& file)
-  deprecated in favour of wxFileSystem (other zip ctors are not deprecated).
