v2.10.0

• Fixed inference of self in binary operations in which self
  is part of a list or tuple.

  Closes pylint-dev/pylint#4826

• Fixed builtin inference on property calls not calling the postinit of the new node, which
  resulted in instance arguments missing on these nodes.

• Fixed a crash on Super.getattr when the attribute was previously uninferable due to a cache
  limit size. This limit can be hit when the inheritance pattern of a class (and therefore of the
  __init__ attribute) is very large.

  Closes pylint-dev/pylint#5679

• Include names of keyword-only arguments in astroid.scoped_nodes.Lambda.argnames.

  Closes pylint-dev/pylint#5771

• Fixed a crash inferring on a NewType named with an f-string.

  Closes pylint-dev/pylint#5770

• Add support for attrs v21.3.0 which
  added a new attrs module alongside the existing attr.

  Closes #1330

• Use the end_lineno attribute for the NodeNG.tolineno property
  when it is available.

  Closes #1350

• Add is_dataclass attribute to ClassDef nodes.

• Use sysconfig instead of distutils to determine the location of
  python stdlib files and packages.

  Closes #1282
  Ref #1103

• Fixed crash with recursion error for inference of class attributes that referenced
  the class itself.

  Closes pylint-dev/pylint#5408

• Fixed crash when trying to infer items() on the __dict__
  attribute of an imported module.

  Closes #1085

• Add optional NodeNG.position attribute.
  Used for block nodes to highlight position of keyword(s) and name
  in cases where the AST doesn't provide good enough positional information.
  E.g. nodes.ClassDef, nodes.FunctionDef.

• Fix ClassDef.fromlineno. For Python < 3.8 the lineno attribute includes decorators.
  fromlineno should return the line of the class statement itself.

• Performance improvements. Only run expensive decorator functions when
  non-default Deprecation warnings are enabled, eg. during a Pytest run.

  Closes #1383
