-_Black_ will remove trailing newlines after code block openings. That means that the

 ```python
 def my_func():

-

 ```
 
 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:
+    ...
+```

+
+
+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))
+```
