With the deprecation of the "add_renderer_globals" feature of the + configurator, there was no way to override an existing value in the + renderer globals dictionary that already existed. Now, the event object + will overwrite an older value that is already in the globals dictionary + when its ``__setitem__`` or ``update`` is called (as well as the new + ``setdefault`` method), just like a plain old dictionary. As a result, for + maximum interoperability with other third-party subscribers, if you write + an event subscriber meant to be used as a BeforeRender subscriber, your + subscriber code will now need to (using ``.get`` or ``__contains__`` of the + event object) ensure no value already exists in the renderer globals + dictionary before setting an overriding value. + 1.1b1 (2011-07-10) ================== |
