It enables objects to be serialized and stored, typically in a ZODB database, while maintaining the performance and behavioral characteristics of ExtensionClass-based inheritance. The package is mature (first released 2008) and actively maintained, with wheels built for modern Python versions across multiple platforms.\n\nUnless your application specifically requires ExtensionClass semantics\u2014such as tight integration with Zope framework components or legacy code that depends on ExtensionClass behavior\u2014the package documentation recommends using persistent.Persistent from the persistent distribution instead. This package is a narrower, specialized tool for Zope-centric persistence patterns.","worth_installing":"Yes, if you are building or maintaining Zope 5 applications that explicitly require ExtensionClass semantics for persistence. The package is actively maintained, has no known vulnerabilities, and supports current Python versions. No, if you are starting a new persistence layer outside Zope or can use persistent.Persistent instead\u2014this is a specialized variant, not a general-purpose persistence tool.
