+<p>If you use the Precreate/Create method of instantiating a window, (for
+example, to set an extended style flag, or for XRC handlers) then
+there is now a new method named PostCreate to help with transplanting
+the brain of the prewindow instance into the derived window instance.
+For example:</p>
+<pre class="literal-block">
+class MyDialog(wx.Dialog):
+ def __init__(self, parent, ID, title, pos, size, style):
+ pre = wx.PreDialog()
+ pre.SetExtraStyle(wx.DIALOG_EX_CONTEXTHELP)
+ pre.Create(parent, ID, title, pos, size, style)
+ self.PostCreate(pre)
+</pre>
+</div>
+<div class="section" id="sizers">
+<h1><a name="sizers">Sizers</a></h1>
+<p>The hack allowing the old "option" keyword parameter has been removed.
+If you use keyworkd args with wxSizer Add, Insert, or Prepend methods
+then you will need to use the "proportion" name instead of "option".</p>
+<p>When adding a spacer to a sizer you now need to use a wxSize or a
+2-integer sequence instead of separate width and height parameters.</p>
+<p>The wxGridBagSizer class (very similar to the RowColSizer in the
+library) has been added to C++ and wrapped for wxPython. It can also
+be used from XRC.</p>
+<p>You should not use AddWindow, AddSizer, AddSpacer (and similar for
+Insert, Prepend, and etc.) methods any longer. Just use Add and the
+wrappers will figure out what to do.</p>
