+wx.ADJUST_MINSIZE is now the default behaviour for window items in
+sizers. This means that the item's GetMinSize and/or GetBestSize will
+be called when calculating layout and the return value from that will
+be used for the minimum size. The wx.FIXED_MINSIZE flag was added
+that will cause the sizer to *not* call window methods to determine
+the new best size, instead the minsize that the window had when added
+to the sizer (or the size the window was created with) will always be
+used. When a window is added to a sizer it's initial size, if any, is
+set as the window's minimal size using SetSizeHints if there isn't
+already a minimal size.
+
+Added some convenience methods to wx.Bitmap: SetSize, GetSize, and
+wx.EmptyBitmap can be called with a wx.Size (or a 2-element sequence)
+object too. Similar changes were done for wx.Image as well.
+
+Added new MaskedEditControl code from Will Sadkin. The modules are
+now locaed in their own sub-package, wx.lib.masked. Demos updated.
