 Unnecessary parentheses are stripped. The stability and status of this feature is

-### Removing newlines in the beginning of code blocks
-
-_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`.
-
-### 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)
