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.
+
+
+- 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 library 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.
+
+
Changes in behaviour not resulting in compilation errors, please read this!
---------------------------------------------------------------------------
- WXWIN_COMPATIBILITY_2_4 doesn't exist any more, please update your code if
you still relied on features deprecated since version 2.4
+- wxDC classes hierarchy has changed, if you derived any classes from wxDC you
+ need to review them as wxDC doesn't have any virtual methods any longer and
+ uses delegation instead of inheritance to present different behaviours.
+
- 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
- Removed global GetLine() function from wx/protocol/protocol.h, use
wxProtocol::ReadLine() instead.
+
+- wxVariant no longer derives from wxObject. wxVariantData also no longer
+ derives from wxObject; instead of using wxDynamicCast with wxVariantData you
+ can use the macro wxDynamicCastVariantData with the same arguments.
+
+- wxWindow::Next/PrevControlId() don't exist any more as they can't be
+ implemented correctly any longer because automatically generated ids are not
+ necessarily allocated consecutively any more. Use GetChildren() to find the
+ next/previous control sibling instead.
