+
+- numeric literals are now formatted by _Black_ (#452, #461, #464, #469):
+
+ - numeric literals are normalized to include `_` separators on Python 3.6+ code
+
+ - added `--skip-numeric-underscore-normalization` to disable the above behavior and
+ leave numeric underscores as they were in the input
+
+ - code with `_` in numeric literals is recognized as Python 3.6+
+
+ - most letters in numeric literals are lowercased (e.g., in `1e10`, `0x01`)
+
+ - hexadecimal digits are always uppercased (e.g. `0xBADC0DE`)
+
+- added `blackd`, see [its documentation](#blackd) for more info (#349)
+
+- adjacent string literals are now correctly split into multiple lines (#463)
+
+- trailing comma is now added to single imports that don't fit on a line (#250)
+
+- cache is now populated when `--check` is successful for a file which speeds up
+ consecutive checks of properly formatted unmodified files (#448)
+
+- whitespace at the beginning of the file is now removed (#399)
+
+- fixed mangling [pweave](http://mpastell.com/pweave/) and

+
+- fixed scope of `# fmt: off` when directly preceding `yield` and other nodes (#385)
+
+- fixed formatting of lambda expressions with default arguments (#468)
+

+ be a bad idea (#415)
+
+### 18.6b4
+
+- hotfix: don't freeze when multiple comments directly precede `# fmt: off` (#371)
+
+### 18.6b3
+
+- typing stub files (`.pyi`) now have blank lines added after constants (#340)
+

+ - they now work also within bracket pairs (#329)
+
+ - they now correctly work across function/class boundaries (#335)
+
+ - they now work when an indentation block starts with empty lines or misaligned
+ comments (#334)
+

+ likelihood we'll need to access non-ASCII file paths when dealing with Python source
+ code is low (#277)

+ (#322)
+
