+  ANSI but may be NULL. This change is normally backwards compatible except:

 
 

-- Some structure fields have been changed from "wxChar *" to "char *" too:
-  e.g. wxCmdLineEntryDesc fields.
+  a) Virtual functions: derived classes versions must be modified to take
+     "const wxString&" as well to make sure that they continue to override the
+     base class version.
+
+  b) Passing NULL as argument: as NULL can't be unambiguously converted to
+     wxString, in many cases code using it won't compile any more and NULL
+     should be replaced with an empty string.
+
+
+- Some structure fields which used to be of type "const wxChar *" (such as
+  wxCmdLineEntryDesc::shortName, longName and description fields) are now of
+  type "const char *", you need to remove wxT() or _T() around the values used
+  to initialize them (which should normally always be ASCII).
+
+- wxIPC classes didn't work correctly in Unicode build before, this was fixed
+  but at a price of breaking backwards compatibility: many methods which used
+  to work with "wxChar *" before use "void *" now (some int parameters were
+  also changed to size_t). While wxIPC_TEXT can still be used to transfer 7
+  bit text, the new wxIPC_UTF8TEXT format is used for transferring wxStrings.

+wxODBC and contrib libraries removal
+------------------------------------
+
+wxODBC library was unmaintained since several years and we couldn't continue
+supporting it any longer so it was removed. Please use any of the other open
+source ODBC libraries in the future projects.
+
+Also the "applet", "deprecated", "fl", "mmedia" and "plot" contrib libraries
+were removed as they were unmaintained and broken since several years.
+The "gizmos", "ogl", "net" and "foldbar" contribs have been moved to
+wxCode (see http://wxcode.sourceforge.net/complist.php); they are now
+open for futher development by volunteers.
+
+The "stc" and "svg" contribs instead have been moved respectively into a new
+"official" library stc and in the core lib.
