-------------------------------------------------------------------------------

INCOMPATIBLE CHANGES SINCE 2.8.x
================================

Changes in behaviour not resulting in compilation errors, please read this!
---------------------------------------------------------------------------

- Default location of wxFileConfig files has changed under Windows, you will
  need to update your code if you access these files directly.

- wxWindow::IsEnabled() now returns false if a window parent (and not
  necessarily the window itself) is disabled, new function IsThisEnabled()
  with the same behaviour as old IsEnabled() was added.

- Generating wxNavigationKeyEvent events doesn't work any more under wxGTK (and
  other platforms in the future), use wxWindow::Navigate() or NavigateIn()
  instead.

Changes in behaviour which may result in compilation errors
-----------------------------------------------------------

- WXWIN_COMPATIBILITY_2_4 doesn't exist any more, please update your code if
  you still relied on features deprecated since version 2.4

- Return type of wxString::operator[] and wxString::iterator::operator* is no
  longer wxChar (i.e. char or wchar_t), but wxUniChar. This is not a problem
  in vast majority of cases because of conversion operators, but it can break
  code that depends on the result being wxChar.

- The value returned by wxString::c_str() cannot be casted to non-const char*
  or wchar_t* anymore. The solution is to use newly added wxString methods
  char_str() (which returns a buffer convertible to char*) or wchar_str()
  (which returns a buffer convertible to wchar_t*). These methods are
  available in wxWidgets 2.8 series beginning with 2.8.4 as well.

- The value returned by wxString::operator[] or wxString::iterator cannot be
  used in switch statements anymore, because it's a class instance. Code like
  this won't compile:
     switch (str[i]) { ... }
  and has to be replaced with this:
     switch (str[i].GetValue()) { ... }

- Return type of wxString::c_str() is now wxCStrData struct and not
  const wxChar*. wxCStrData is implicitly convertible to const char* and
  const wchar_t*, so this only presents a problem if the compiler cannot
  convert the type. In particular, Borland C++ and DigitalMars compilers
  don't correctly convert operator?: operands to the same type and fail with
  compilation error instead. This can be worked around by explicitly casting
  to const wxChar*:
     wxLogError(_("error: %s"), !err.empty() ? (const wxChar*)err.c_str() : "")

- DigitalMars compiler has a bug that prevents it from using
  wxUniChar::operator bool in conditions and it erroneously reports type
  conversion ambiguity in expressions such as this:
     for ( wxString::const_iterator p = s.begin(); *p; ++p )
  This can be worked around by explicitly casting to bool:
     for ( wxString::const_iterator p = s.begin(); (bool)*p; ++p )

Deprecated methods and their replacements
-----------------------------------------

- wxCreateGreyedImage() deprecated, use wxImage::ConvertToGreyscale() instead.
- wxString::GetWriteBuf() and UngetWriteBuf() deprecated, using wxStringBuffer
  or wxStringBufferLength instead.
