- `is_typing_guard`
`is_sys_guard` is still available, which was part of
`is_node_in_guarded_import_block`.

### [`v2.17.0`](https://redirect.github.com/pylint-dev/pylint/releases/tag/v2.17.0)
[Compare Source](https://redirect.github.com/pylint-dev/pylint/compare/v2.16.4...v2.17.0)
2.17 is a small release that is the first to support python 3.11 officially
with the addition of TryStar nodes.
There's still two new default checks: `bad-chained-comparison` and
`implicit-flag-alias`, one of them already fixed a previously undetected
bug in sentry.
Thanks to the community effort our documentation is almost complete,
and almost all messages should have a proper documentation now.
A big thank you to everyone who participated !
The next release is going to be `3.0.0`, bring breaking changes and
enact long announced deprecations. There's going to be frequent beta
releases, before the official releases, everyone is welcome to try the betas
so we find problems before the actual release.

### Summary -- Release highlights
In 2.16.0 we added aggregation and composition understanding in `pyreverse`, and a way to clear
the cache in between run in server mode (originally for the VS Code integration). Apart from the bug
fixes there's also a lot of new checks, and new extensions that have been asked for for a long time
that were implemented.
If you want to benefit from all the new checks load the following plugins::
pylint.extensions.dict_init_mutate,
pylint.extensions.dunder,
pylint.extensions.typing,
pylint.extensions.magic_value,
We still welcome any community effort to help review, integrate, and add good/bad examples to the doc for
[#5953](https://redirect.github.com/pylint-dev/pylint/issues/5953). This should be doable without any `pylint` or `astroid`
knowledge, so this is the perfect entrypoint if you want to contribute to `pylint` or open source without
any experience with our code!
Last but not least [@clavedeluna](https://redirect.github.com/clavedeluna) and [@nickdrozd](https://redirect.github.com/nickdrozd) became triagers, welcome to the team !
#### What's new in Pylint 2.16.0?
#### Changes requiring user actions
- The `accept-no-raise-doc` option related to `missing-raises-doc` will now
be correctly taken into account all the time.
Pylint will no longer raise missing-raises-doc (W9006) when no exceptions are
documented and accept-no-raise-doc is true (issue [#7208](https://redirect.github.com/pylint-dev/pylint/issues/7208)).
If you were expecting missing-raises-doc errors to be raised in that case,
you
will now have to add `accept-no-raise-doc=no` in your configuration to keep
the same behavior.
Closes [#7208](https://redirect.github.com/pylint-dev/pylint/issues/7208)
#### New Features
- Added the `no-header` output format. If enabled with
`--output-format=no-header`, it will not include the module name in the
output.
Closes [#5362](https://redirect.github.com/pylint-dev/pylint/issues/5362)
- Added configuration option `clear-cache-post-run` to support server-like
usage.
Use this flag if you expect the linted files to be altered between runs.
Refs [#5401](https://redirect.github.com/pylint-dev/pylint/issues/5401)
- Add `--allow-reexport-from-package` option to configure the
`useless-import-alias` check not to emit a warning if a name
is reexported from a package.
Closes [#6006](https://redirect.github.com/pylint-dev/pylint/issues/6006)
- Update `pyreverse` to differentiate between aggregations and compositions.
`pyreverse` checks if it's an Instance or a Call of an object via method
parameters (via type hints)
to decide if it's a composition or an aggregation.
Refs [#6543](https://redirect.github.com/pylint-dev/pylint/issues/6543)
#### New Checks
- Adds a `pointless-exception-statement` check that emits a warning when an
Exception is created and not assigned, raised or returned.
Refs [#3110](https://redirect.github.com/pylint-dev/pylint/issues/3110)
- Add a `shadowed-import` message for aliased imports.
Closes [#4836](https://redirect.github.com/pylint-dev/pylint/issues/4836)
- Add new check called `unbalanced-dict-unpacking` to check for unbalanced
dict unpacking
in assignment and for loops.
Closes [#5797](https://redirect.github.com/pylint-dev/pylint/issues/5797)
- Add new checker `positional-only-arguments-expected` to check for cases
when
positional-only arguments have been passed as keyword arguments.
Closes [#6489](https://redirect.github.com/pylint-dev/pylint/issues/6489)
- Added `singledispatch-method` which informs that `@singledispatch` should
decorate functions and not class/instance methods.
Added `singledispatchmethod-function` which informs that
`@singledispatchmethod` should decorate class/instance methods and not
functions.
Closes [#6917](https://redirect.github.com/pylint-dev/pylint/issues/6917)
- Rename `broad-except` to `broad-exception-caught` and add new checker
`broad-exception-raised`
which will warn if general exceptions `BaseException` or `Exception` are
raised.
Closes [#7494](https://redirect.github.com/pylint-dev/pylint/issues/7494)
- Added `nested-min-max` which flags `min(1, min(2, 3))` to simplify to
`min(1, 2, 3)`.
Closes [#7546](https://redirect.github.com/pylint-dev/pylint/issues/7546)
- Extended `use-dict-literal` to also warn about call to `dict()` when
passing keyword arguments.
Closes [#7690](https://redirect.github.com/pylint-dev/pylint/issues/7690)
- Add `named-expr-without-context` check to emit a warning if a named
expression is used outside a context like `if`, `for`, `while`, or
a comprehension.
Refs [#7760](https://redirect.github.com/pylint-dev/pylint/issues/7760)
- Add `invalid-slice-step` check to warn about a slice step value of `0`
for common builtin sequences.
Refs [#7762](https://redirect.github.com/pylint-dev/pylint/issues/7762)
- Add `consider-refactoring-into-while-condition` check to recommend
refactoring when
a while loop is defined with a constant condition with an immediate `if`
statement to check for `break` condition as a first statement.
Closes [#8015](https://redirect.github.com/pylint-dev/pylint/issues/8015)
#### Extensions
- Add new extension checker `dict-init-mutate` that flags mutating a
dictionary immediately
after the dictionary was created.
Closes [#2876](https://redirect.github.com/pylint-dev/pylint/issues/2876)
- Added `bad-dunder-name` extension check, which flags bad or misspelled
dunder methods.
You can use the `good-dunder-names` option to allow specific dunder names.
Closes [#3038](https://redirect.github.com/pylint-dev/pylint/issues/3038)
- Added `consider-using-augmented-assign` check for `CodeStyle` extension
which flags `x = x + 1` to simplify to `x += 1`.
This check is disabled by default. To use it, load the code style extension
with `load-plugins=pylint.extensions.code_style` and add
`consider-using-augmented-assign` in the `enable` option.

- Fixed a case where custom plugins specified by command line could silently
fail.
Specifically, if a plugin relies on the `init-hook` option changing
`sys.path` before
it can be imported, this will now emit a `bad-plugin-value` message. Before
this
change, it would silently fail to register the plugin for use, but would load
any configuration, which could have unintended effects.

- Adds test for existing preferred-modules configuration functionality.
Refs [#7957](https://redirect.github.com/pylint-dev/pylint/issues/7957)
#### Internal Changes
- Add and fix regression tests for plugin loading.
This shores up the tests that cover the loading of custom plugins as affected
by any changes made to the `sys.path` during execution of an `init-hook`.
Given the existing contract of allowing plugins to be loaded by fiddling with
the path in this way, this is now the last bit of work needed to close Github
issue [#7264](https://redirect.github.com/pylint-dev/pylint/issues/7264).
