Changelog
### 2.3.0
```
===========================
Release date: 2019-02-27
* Protect against `NonDeducibleTypeHierarchy` when calling semi-private `is_subtype`
`astroid.helpers.is_subtype` raises `NonDeducibleTypeHierarchy` when it cannot infer
the base classes of the given types, but that makes sense in its context given that
the method is mostly used to inform the inference process about the hierarchy of classes.
Doesn't make that much sense for ``pylint`` itself, which is why we're handling the
exception here, rather than in ``astroid``
Close PyCQA/astroid644
* Added a new command line option ``list-groups`` for listing all the check groups ``pylint`` knows about.
* Allow ``BaseException`` for emitting ``broad-except``, just like ``Exception``.
Close 2741
* Fixed a crash that occurred for ``bad-str-strip-call`` when ``strip()`` received ``None``
Close 2743
* Don't emit ``*-not-iterating`` checks for builtins consumed by ``itertools``
Close 2731
* Fix a crash caused by iterating over ``Uninferable`` in a string formatting check.
Close 2727
* Fixed false positives for ``no-self-argument`` and ``unsubscriptable-object`` when using ``__class_getitem__`` (new in Python 3.7)
Close 2416
* Support ``Ellipsis`` as a synonym for ``pass`` statements.
Close 2718
* ``fixme`` gets triggered only on comments.
Close 2321
* Fixed a false positive for ``unused-variable`` and ``nonlocal`` assignments
Close 2671
* Added ``load_configuration()`` hook for plugins
New optional hook for plugins is added: ``load_configuration()``.
This hook is executed after configuration is loaded to prevent
overwriting plugin specific configuration via user-based
configuration.
Close 2635
* Fix missing-raises-doc false positive (W9006)
Close 1502
* Exempt starred unpacking from ``*-not-iterating`` Python 3 checks
Close 2651
* Make ``compare-to-zero`` less zealous by checking against equality and identity
Close 2645
* Add ``no-else-raise`` warning (R1720)
Close 2558
* Exempt ``yield from`` from ``*-not-iterating`` Python 3 checks.
Close 2643
* Fix incorrect generation of ``no-else-return`` warnings (R1705)
Fixed issue where ``if`` statements with nested ``if`` statements
were incorrectly being flagged as ``no-else-return`` in some cases and
not being flagged as ``no-else-return`` in other cases. Added tests
for verification and updated pylint source files to eliminate newly
exposed warnings.
* Fix false positive with `not-async-context-manager` caused by not understanding `contextlib.asynccontextmanager`
Close 2440
* Refactor ``bad-reversed-sequence`` to account for more objects that can define ``__reversed__``
One such object would be an enum class, for which ``__reversed__`` yields each individual enum.
As such, the check for ``bad-reversed-sequence`` needs to not differentiate between classes
and instances when it comes for checking of ``__reversed__`` presence.
Close 2598
* Added ``wrong-exception-operation``
Used when an operation is done against an exception, but the operation
is not valid for the exception in question. Usually emitted when having
binary operations between exceptions in except handlers.
Close 2494
* ``no-member`` is emitted for enums when they lack a member
Previously we weren't doing this because we detected a
``__getattr__`` implementation on the ``Enum`` class
(and this check is skipped for classes with ``__getattr__``),
but that is fine for Enums, given that they are inferred in a customised
way in astroid.
Close 2565
* Generalize ``chained-comparison``
Previous version incorrectly detects `a < b < c and b < d` and fails to
detect `a < b < c and c < d`.
* Avoid popping __main__ when using multiple jobs
Close 2689
* Add a new option 'check-str-concat-over-line-jumps' to check 'implicit-str-concat-in-sequence'
* Fixes for the new style logging format linter.
The number of arguments was not handled properly, leading to an always
successful check.
* Fix false positive ``not-callable`` for uninferable properties.
* Fix false positive ``useless-else-on-loop`` if the break is deep in the else
of an inner loop.
