+This won't really affect wxPython all that much, other than the fact +that the wxwindows.org domain name will be changing to wxwidgets.org, +so mail list, CVS, and etc. addresses will be changing.

The wx.Menu methods that add items to a wx.Menu have been modified +such that they return a reference to the wx.MenuItem that was created. +Additionally menu items and toolbar items have been modified to +automatically generate a new ID if -1 is given, similar to using -1 +with window classess.
