Richer lifecycle events API.

Project description

This package defines three “lifecycle” events that notify about object creation, modification and deletion. The events include information about the user responsible for the changes.

The modification event also includes information about the state of the object before the changes.

The module also contains Snapshot support to save the state of an object for notification, and to compute deltas between version of objects.
