limit. Line continuation backslashes are converted into parenthesized strings.
Unnecessary parentheses are stripped. The stability and status of this feature is
tracked in [this issue](https://github.com/psf/black/issues/2188).
-
-### Improved empty line management
-
-1. _Black_ will remove newlines in the beginning of new code blocks, i.e. when the
- indentation level is increased. For example:
-
- ```python
- def my_func():
-
- print("The line above me will be deleted!")
- ```
-
- will be changed to:
-
- ```python
- def my_func():
- print("The line above me will be deleted!")
- ```
-
- This new feature will be applied to **all code blocks**: `def`, `class`, `if`,
- `for`, `while`, `with`, `case` and `match`.
-
-2. _Black_ will enforce empty lines before classes and functions with leading comments.
- For example:
-
- ```python
- some_var = 1
- # Leading sticky comment
- def my_func():
- ...
- ```
-
- will be changed to:
-
- ```python
- some_var = 1
-
-
- # Leading sticky comment
- def my_func():
- ...
- ```
-
-### Improved parentheses management
-
-_Black_ will format parentheses around return annotations similarly to other sets of
-parentheses. For example:
-
-```python
-def foo() -> (int):
- ...
-
-def foo() -> looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong:
- ...
-```
-
-will be changed to:
-
-```python
-def foo() -> int:
- ...
-
-
-def foo() -> (
- looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong
-):
- ...
-```
-
-And, extra parentheses in `await` expressions and `with` statements are removed. For
-example:
-
-```python
-with ((open("bla.txt")) as f, open("x")):
- ...
-
-async def main():
- await (asyncio.sleep(1))
-```
-
-will be changed to:
-
-```python
-with open("bla.txt") as f, open("x"):
- ...
-
-
-async def main():
- await asyncio.sleep(1)
-```
