 to call usleep()) in idle time - giving more CPU slices to
 the application if desired.

 There have been slight changes to the priting dialogs and their
 setup data (which might break apps using this code in previous
 versions). Also, a bug concerning printing white has been fixed

 Although this is only the first 2.1 snapshot, there is little reason not
 to use it as many bugs from version 2.0 have been corrected. There are,
 pf course, still a few problem left with GTK 1.2 (some of which relate
 to bugs in GTK).

 There is one field where we haven't been able to fix the API yet, and that
 it Drag'n'Drop. This is mostly due to the fact that DnD in
 GTK 1.0 is hardly usable and much different from GTK 1.2 which means that
 we have to design a common API for Windows, GTK 1.0 and GTK 1.2. Although
 we are trying to prevent that, it is possible that wxWindows 2.0 (being
 based on GTK 1.0) will not have proper DnD support.

 For those who are using the ever-so-popular wxImage class (which
 now available on Motif and Windows as well) in 8-bit mode: wxGTK
 now creates a color cube upon start-up in 8-bit mode and thus the
 generation of bitmaps from images has been speeded up 20 times.
- 
+
 It is now possible to develop with wxGTK without having the GTK 1.0 header
 files installed so that having the GTK 1.2 header files installed no longer
 is any problem. We also provide RPMs for RedHat glibc 2 based systems, compiled
 with egcs 1.1.1 on SuSE 6.0. Note that the RPM will   not   work in
 SuSE 6.0 as SuSE decided to ship 6.0 with a broken GTK+ package.

 This is the second beta release and contains it mostly build and
 bug fixes. Threads work well now on (up-to-date) glibc 2 systems,
 commercial Unices and Windows.

 This is the first beta release and we have used the time before
 this release to tidy up some parts of the API. All releases from
 now on will be source code compatible but we reserve binary compatibility
 for the final release. Because of this, the actual library name of

+the beta version will not be 2.0 but 1.99, so that we prevent
 conflicts with the final library later on. After the final release
 we'll only fix bugs so that there will be no reason to link any
 program statically with wxGTK.
- 
+
 We changed the name of the shared library to include the version of
 the GTK used so that no conflicts emerge with simultaneous
 versions of wxWindows for GTK 1.0 and for GTK 1.2 and so on.
- 
+
 As you can see, we have not moved to GTK 1.1.X as the different
 development versions are too different and buggy to be useful. We'll
 wait for a stable GTK 1.2 release (hardly 1.2.0) and start porting
 then.
- 
+
 wxGTK now compiles without problems on anything between gcc 2.7.2 on
 Linux-x86 and egcs 1.1 on Linux-Alpha and egcs 1.0 on Sparc. This isn't
 as easy as it sounds...
- 
+
 Available form this site are the Python bindings of wxWindows.
 Thanks to Robin Dunn for this tremendous contribution.
 Tkinter is dead, Java is dead, wxPython rules! That's all there is to say.

+
 Although only a few new classes have been added, many have been polished
 up substantially, the most visible are wxListCtrl, wxTreeCtrl and
 all classes related to printing. Also the DialogEd now functions
-much better than before. Drag'n'Drop is fucntional but probably won't 
+much better than before. Drag'n'Drop is fucntional but probably won't
 be perfect until we use GTK 1.2 and its much improved DnD features.
- 
+
 wxClipboard has arrived and works for text. Other formats have not been
 tested carefully yet.
- 
+
 wxMiniFrame has been added which might be useful for docking toolbars
 etc. Someone has already done that for the MSW port and we hope to
 include his very nice work later.
- 
+
 wxDirDialog has been added (thanks to Harm von der Heijden).
- 
+
 The entite "tab traveral" system for moving from item to item in
 a dialog has been rewritten. It now completely overrides the
 not-so-well-done GTK native tab system.
- 
+
 Quite much has been done to improve the wxImage class, which is now
 available in the Windows port as well. Very useful for anything related
 to image processing. wxGTK also uses this class internally e.g. to scale
 bitmaps when the scale factor (e.g. zooming) of a drawing context
 has changed.
-  
+
 Some of the small and handy classes (wxDate, wxTime, wxVariant) have
 received a face-lift. wxList has been rewritten to make it possible
 to write type-safe lists. The collection of utility functions (wxFileFind etc)
 has been revamped and cleaned-up (thanks to Vadim Zeitlin, who has also
 greatly enhanced many basic classes, ranging wxString to the debug and
 log system).
- 
+
 We removed some constructors of GDI classes (such as wxPen, wxColour)
 which took a pointer as a parameter. This lead to many errors among users
 resulting in unexpected behaviour so it was decided to remove these
 constructors.
- 
+
 As the number of users and the number of test programs and samples
 is steadialy rising the core classes of wxWindows for MSW and GTK 1.0
 can be considered to be very stable if not outright bug-free. I haven't
