v1.0

Frigid v1.0 (2024-12-05)

Features

• Add @immutable decorator for making instances of existing classes immutable
  after initialization. Compatible with most classes except those defining their
  own __setattr__ or __delattr__ methods.

• Add Module class and reclassify_modules function for creating and
  converting to immutable modules. This prevents runtime modification of module
  attributes, helping ensure interface stability.

• Add Namespace class providing a completely immutable alternative to
  types.SimpleNamespace. All attributes must be set during initialization
  and cannot be modified afterward.

• Add Object base class for creating objects with immutable attributes.
  Derived classes must set attributes in __init__ before calling
  super().__init__().

• Add immutable dictionaries, which have additional methods, such as copy and
  with_data, additional operations, such as union (|) and intersection
  (&):

  • Dictionary for simple immutable mappings
  • ValidatorDictionary which uses a provided validator function

• Add metaclasses for creating classes with immutable class attributes:

  • Class for standard classes
  • ABCFactory for abstract base classes
  • ProtocolClass for protocol classes

• Add qualified aliases in qaliases module with "Immutable" prefix for all
  core classes, helping avoid namespace conflicts.

Supported Platforms

• Add support for CPython 3.10 to 3.13.
• Add support for PyPy 3.10.
