Hi!

The invalidation of individual cache entries is now working fine and 
across all ZEO instances - this is when we know a priori the explicit 
list of objects to monitor for changes (for instance the breadcrumbs 
entries, the current folder object, ...). The invalidation is lazy, not 
effective immediately, it occurs when the portlet is rendered again - 
for the user it makes no difference: the portlet's content is always 
correct.

Otherwise when active invalidation is required (when a document is 
published, deleted, ...) the only solution is to ask the event service, 
so until the CPS event service is ported to CMF / Plone there will be 
some portlets that we won't be able to cache.
