attrs versions available: 18.1.0

[dependencies]

There are new versions of attrs available from pypi.

18.1.0

Changes

• x=X(); x.cycle = x; repr(x) will no longer raise a
  RecursionError, and will instead show as X(x=...).

  #95

• attr.ib(factory=f) is now syntactic sugar for the common case of
  attr.ib(default=attr.Factory(f)).

  #178,
  #356

• Added attr.field_dict() to return an ordered dictionary of attrs
  attributes for a class, whose keys are the attribute names.

  #290,
  #349

• The order of attributes that are passed into attr.make_class() or
  the these argument of @attr.s() is now retained if the
  dictionary is ordered (i.e. dict on Python 3.6 and later,
  collections.OrderedDict otherwise).

  Before, the order was always determined by the order in which the
  attributes have been defined which may not be desirable when
  creating classes programatically.

  #300,
  #339,
  #343

• In slotted classes, __getstate__ and __setstate__ now ignore the
  __weakref__ attribute.

  #311,
  #326

• Setting the cell type is now completely best effort. This fixes
  attrs on Jython.

  We cannot make any guarantees regarding Jython though, because our
  test suite cannot run due to dependency incompatabilities.

  #321,
  #334

• If attr.s is passed a these argument, it will not attempt to
  remove attributes with the same name from the class body anymore.

  #322,
  #323

• The hash of attr.NOTHING is now vegan and faster on 32bit Python
  builds.

  #331,
  #332

• The overhead of instantiating frozen dict classes is virtually
  eliminated.
  #336

• Generated __init__ methods now have an __annotations__ attribute
  derived from the types of the fields.

  #363

• We have restructured the documentation a bit to account for
  attrs' growth in scope. Instead of putting everything into the
  examples page, we
  have started to extract narrative chapters.

  So far, we've added chapters on
  initialization and
  hashing.

  Expect more to come!

  #369,
  #370

It's the spiritual successor of
characteristic and aspires to
fix some of it clunkiness and unfortunate decisions. Both were inspired
by Twisted's
FancyEqMixin
but both are implemented using class decorators because sub-classing is
bad for you, m'kay?
