v3.0

Frigid v3.0 (2025-03-05)

Documentation Improvements

• Improve organization of examples. Improve wording in various places.

Features

• Add metaclasses for immutable dataclasses including Dataclass,
  CompleteDataclass, ProtocolDataclass, and
  CompleteProtocolDataclass. These factory classes combine Python's dataclass
  functionality with immutable behavior for type-safe, attribute-stable data
  containers.
• Enhance the immutable decorator to accept optional parameters including
  docstring for setting or overriding class documentation and mutables
  for specifying attributes that should remain modifiable after initial
  assignment.
