+wx.ADJUST_MINSIZE is now the default behaviour for window items in
+sizers.  This means that the item's GetAdjustedBestSize will be called
+when calculating layout and the return value from that will be used
+for the minimum size.  Added wx.FIXED_SIZE flag for when you would
+like the old behavior but you should only need it when your desired
+size is smaller than the item's GetBestSize()

 When adding a spacer to a sizer you now need to use a wx.Size or a
 2-integer sequence instead of separate width and height parameters.
+This allows for more consistency in how you add the various types of
