1.3.0 – 2023-10-04

A redesign of the extension points, on metaclasses.

• Changed – the protocol, reassembly, flow-tracing, engine, vendor and field base classes are all built on metaclasses, which is what registers a subclass and fixes its name and module.

• Added – ModuleDescriptor, so a registry entry can name a module and class that are imported lazily on first use rather than at registration; the registry functions accept it throughout. VersionInfo gained a version property.

• Changed – _Engine renamed EngineBase; the beholder decorator logs the error it swallows under devmode and verbose mode.
