Zope Lifecycle Events

Zope.lifecycleevent provides a standard set of event objects and convenience functions for describing the lifecycle of objects within a Zope application or any Python system using `zope.event`. This includes events for object creation, modification, addition, removal, and copying. The library is currently at version 6.0 and actively maintained, with new minor versions typically released every 2-6 months and major versions every 2-3 years, aligning with the broader Zope ecosystem.
