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

+Unicode-related changes
+-----------------------
+
+The biggest changes in wxWidgets 3.0 are the changes due to the merge of the
+old ANSI and Unicode build modes in a single build. See the Unicode overview
+in the manual for more details but here are the most important incompatible
+changes:
+
+- Many wxWidgets functions taking "const wxChar *" have been changed to take
+  either "const wxString&" so that they accept both Unicode and ANSI strings.
+  and the argument can't be NULL or "const char *" if the strings are always
+  ANSI but may be NULL. This change is normally backwards compatible except:
+
+  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. The same issue also applies to
+     the structure fields which used to contain "const wxChar *" pointers (such
+     as wxCmdLineEntryDesc::shortName, longName and description fields) and are
+     now wxStrings: empty strings should be assigned to them instead of NULL.
+
+
+
