Usually emitted when having + binary operations between exceptions in except handlers. + + Closes #2494 + +* We added a new ``no-else-raise`` warning similar to ``no-else-return`` + + Closes #2558 + + +* We added a new option ``check-str-concat-over-line-jumps`` to check + ``implicit-str-concat-in-sequence`` over multiple lines. + + +Other Changes +============= + +Quite a lot of bug fixes and improvements went into this release: + +* We no longer emit ``*-not-iterating`` checks for builtins consumed by ``itertools`` + +* We fixed some false positives for ``no-self-argument`` and ``unsubscriptable-object`` + when using ``__class_getitem__`` (new in Python 3.7) + +* ``pylint`` now upports ``Ellipsis`` as a synonym for ``pass`` statements. + +* ``fixme`` gets triggered only on comments. + +* ``pylint`` exempts starred unpacking from ``*-not-iterating`` Python 3 checks. + +* ``compare-to-zero`` is now less zealous by checking against equality and identity. + +*``yield from`` is exempted from ``*-not-iterating`` Python 3 checks. + +* A false positive with ``not-async-context-manager`` caused by not understanding + ``contextlib.asynccontextmanager`` was fixed. + +* We refactored ``bad-reversed-sequence`` to account for more objects that can define ``__reversed__``. + +* ``no-member`` is now emitted for enums when they lack a member. + +* Plugins can now use the ``load_configuration()`` hook. + This hook is executed after configuration is loaded to prevent overwriting plugin + specific configuration via user-based configuration. |
