+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 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.
+
+
+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.
+
+- Sizers distribute only the extra space between the stretchable items
+ according to their proportions and not all available space. We believe the
+ new behaviour corresponds better to user expectations but if you did rely
+ on the old behaviour you will have to update your code to set the minimal
+ sizes of the sizer items to be in the same proportion as the items
+ proportions to return to the old behaviour.
+
+- wxWindow::Freeze/Thaw() are not virtual any more, if you overrode them in
+ your code you need to override DoFreeze/Thaw() instead now.
+
+
+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
+
+- 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
+ 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() : "")
+
+- wxCtime() and wxAsctime() return char*; this is incompatible with Unicode
+ build in wxWidgets 2.8 that returned wchar_t*.
+
+- 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 )
+
+- Virtual wxHtmlParser::AddText() takes wxString, not wxChar*, argument now.
+
+- Functions that took wxChar* arguments that could by NULL in wxWidgets 2.8.
+ are deprecated and passing NULL to them won't compile anymore, wxEmptyString
+ must be used instead.
+
+- wxTmemxxx() functions take either wxChar* or char*, not void*: use memxxx()
+ with void pointers.
+
+- Removed insecure wxGets() and wxTmpnam() functions.
+
+- 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.
+
+
+Deprecated methods and their replacements
+-----------------------------------------
+
+- wxCreateGreyedImage() deprecated, use wxImage::ConvertToGreyscale() instead.
+- wxString::GetWriteBuf() and UngetWriteBuf() deprecated, using wxStringBuffer
+ or wxStringBufferLength instead.
+- wxDIRCTRL_SHOW_FILTERS style is deprecated, filters are alwsys shown if
+ specified so this style should simply be removed
+- wxDocManager::MakeDefaultName() replaced by MakeNewDocumentName() and
+ wxDocument::GetPrintableName() with GetUserReadableName() which are simpler
+ to use
+- wxXmlProperty class was renamed to wxXmlAttribute in order to use standard
+ terminology. Corresponding wxXmlNode methods were renamed to use
+ "Attribute" instead of "Property" or "Prop" in their names.
+- wxConnection::OnExecute() is not formally deprecated yet but new code should
+ use simpler OnExec() version which is called with wxString argument
+
+
+Major new features in this release
+----------------------------------
+
+- wxWidgets is now always built with Unicode support but provides the same
+ simple (i.e. "char *"-tolerant) API as was available in ANSI build in the
+ past.
+
+- wxWidgets may now use either wchar_t (UTF-16/32) or UTF-8 internally,
+ depending on what is optimal for the target platform.
+
+- Events loops, timers and sockets can now be used in wxBase, without GUI.
