Version 4.2.0

• Add discard method which return a new immutabledict without the item at the given key, if present. Thanks to @matthiasdiener for the PR #307

Version 4.1.0

• Do not store cached hash value when pickling. Thanks to @matthiasdiener for the PR #287

Version 4.0.0

• Replace __init__ by __new__. Thanks to @spacether for the PR #263
• Add explicit items()/keys()/values() methods to speedup these methods. Thanks to @matthiasdiener for the PR #265
• Add set/delete/update functions. Thanks to @matthiasdiener for the PR #271
• Add documentation at immutabledict.corenting.fr

Version 3.0.0

• copy() (breaking change): remove the option to pass keyword arguments (which were present as key/value pairs in the copy). Now the method doesn't take any arguments (it behaves the same as a normal dict).
• Python versions: drop Python 3.7 support
• Typing: fixes
  • Make the key covariant. Thanks to @spacether for the PR #244
  • Fix key/value typing missing for ImmutableOrderedDict

Version 2.2.5

• Fix hard-coded class reference in fromkeys() resulting in always using dict for fromkeys() (instead of OrderedDict in ImmutableOrderedDict for example). Thanks to @cthoyt for the PR #234

Version 2.2.4

• Include tests in sdist for easier packaging

Version 2.2.3

• Fix TypeError message when using |=. Thanks to @ronshapiro for the PR #66
• Update docstring for ImmutableOrderedDict to indicate that is not needed anymore for Python >= 3.7 but kept for compatibility purposes
• Use postponed evaluation of annotations (PEP 563) for the typing

Version 2.2.2

• Update classifiers, Github Actions... for Python 3.11 (no code changes)

Version 2.2.1

• Update classifiers, Github Actions... for Python 3.10 (no code changes)

Version 2.2.0

• Use poetry-core instead of poetry for build-system. Thanks to @mweinelt for reporting the issue.
