frozendict v1.5.1

• speedup to hash computation
• subclassing frozendict now is safer
• now an exception type and message that is raised by immutability is aligned to the stdlib (tuple, frozenset)

frozendict v1.5.0

Turned back to the dict API:

• removed is_frozendict and initialized attributes. Added _initialized.
• removed __add__() and __sub__() methods (wait for PEP 584)

frozendict v1.4.0

Many, Many changes under and over the hood:

• now copy() and frozendict(another_frozendict) returns the same instance, like all the other CPython immutables
• fixed repr(): previously the result string was cached. Since now frozendict can contains also mutables, this is wrong (and maybe it is wrong also when all the values are immutable...)
• a_frozendict - iterable now supports also text-like (str, bytes...) and generator-like iterables.
• Removed the not-so-useful frozendictbase class.
• Many micro-improvments to speed
• Now attribute initialized is public

frozendict v1.3.5

• Now you can add also unhashable values to a frozendict. If you try to get the hash of such a frozendict, a TypeError will be raised. This is the same behaviour of tuple, immutables.Map and the @slezica's frozendict
• The empty frozendict() is now a singleton, like () and frozenset().
  So (frozendict() is frozendict([])) == True.

frozendict v1.3.4

Code and build cleaning.

frozendict v1.3.3

Speed improvements to constructor.

frozendict v1.3.2

• Some little speed improvements
• Updated benchmarks

frozendict v1.3.1

Some internal code cleaning.

frozendict v1.3

• Speedup to creation of a copy of a frozendict
• Added a testcase
• Added benchmarks

frozendict v1.2

Completely reworked. Now frozendict inherits directly from dict and does not use the slow MappingProxyType anymore. Immutability is preserved anyway.

Notable speed-ups in all methods.
