There is a new version of ArcGis Explorer (410).

I only made one test for simple old version of one of my tasks, it still works.
It looks lie they almost didn't changed the templates of creating new tasks.

API Changes (didn't test it yet, only read about it):

• RemoveLayerCache(Layer) - delete the cahe of a given layer, this one is great!
• CacheType - {Permanent, Session, None} - indicates the way ArcGis Explorer caches the layer.

I will keep checking and update you ASAP.
