This won't really affect wxPython all that much, other than the fact

to try and smooth the transition as much as possible, but I wanted you
all to be aware of this change if you run into any issues.

Insert, Prepend, and etc.) methods any longer. Just use Add and the

AddWindow, AddSize, AddSpacer and etc. will now issue a
DeprecationWarning.
-**[Changed in 2.5.1.6]** wx.ADJUST_MINSIZE is now the default
+**[Changed in 2.5.2.0]** 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. If you
-would like the sizer to use something other than the window's initial
-size as the minimum then you can give it a new minimum by calling its
-SetSizeHints method.
+and the return value from that will be used for the minimum size used
+by the sizer. The wx.FIXED_MINSIZE flag was added that will cause the
+sizer to use the old behaviour in that it will *not* call the window's
+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.
+
+Related to the above, when controls and some other window types are
+created either the size passed to the constructor, or their "best
+size" if an explicit size was not passed in, is set as the window's
+minimal size. For non top-level windows that hasn't meant much in the
+past, but now the sizers are sensitive to the window's minimal size.
+The key point to understand here is that it is no longer the window's
+size it has when added to the sizer that matters, but its minimal
+size. So you might have some issues to iron out if you create a
+control without a size and then set its size to something before
+adding it to the sizer. Since it's minimal size is probably not the
+size you set then the sizer will appear to be misbehaving. The fix is
+to either set the size when calling the window's constructor, or to
+reset the min size by calling SetSizeHints. You can call SetSizeHints
+at anytime to change the minsize of a window, just call the sizer's
+Layout method to redistribute the controls as needed.
+OGL is dead! LONG LIVE OGL!
+---------------------------
+
+**[Changed in 2.5.2.0]**
+
+The wx.ogl module has been deprecated in favor of the new Python port
+of the OGL library located at wx.lib.ogl contributed by Pierre Hjälm.
+This will hopefully greatly extend the life of OGL within wxPython by
+making it more easily maintainable and less prone to getting rusty as
+there seems to be less and less interest in maintaining the C++
+version.
+
+There are only a few known compatibility issues at this time. First
+is the location of OGL. The deprecated version is located in the
+wx.ogl module, and the new version is in the wx.lib.ogl package. So
+this just means that to start using the new version you need to adjust
+your imports. So if your code currently has something like this::
+
+ import wx
+ import wx.ogl as ogl
+
+Then just change it to this::
+
+ import wx
+ import wx.lib.ogl as ogl
+
+The other compatibility issue deals with removing a wart in the
+original API that was necessary in order to allow overloaded methods
+in derived classes to call the same method in the base class when
+using the old SWIG. Instead dedaling with the wart you can now just
+call the base class method like you woudl for any other Python class.
+For example, if you had to do something like this previously::
+
+ class MyDividedShape(ogl.DividedShape):
+ ...
+ def OnSizingEndDragLeft(self, pt, x, y, keys, attch):
+ self.base_OnSizingEndDragLeft(pt, x, y, keys, attch)
+ ...
+
+You will need to change it to be like this::
+
+ class MyDividedShape(ogl.DividedShape):
+ ...
+ def OnSizingEndDragLeft(self, pt, x, y, keys, attch):
+ ogl.DividedShape.OnSizingEndDragLeft(self, pt, x, y, keys, attch)
+ ...
+
+

Obsolete Modules

parameters that expect floating point values.

+**[Changed in 2.5.2.0]** The MaskedEditCtrl modules have been moved
to their own sub-package, wx.lib.masked. See the docstrings and demo
for changes in capabilities, usage, etc.
-**[Changed in 2.5.1.6]** wx.MaskColour constructor has been deprecated
+**[Changed in 2.5.2.0]** wx.MaskColour constructor has been deprecated
and will raise a DeprecationWarning if used. The main wx.Mask
constructor has been modified to be compatible with wx.MaskColour so
you should use it instead.
