+
+* adjacent string literals are now correctly split into multiple lines (#463)

+
+ * most letters in numeric literals are lowercased (e.g., in `1e10` or `0xab`)

+ consecutive checks of properly formatted unmodified files (#448)

+* fixed parsing of `__future__` imports with renames (#389)
+
+* fixed scope of `# fmt: off` when directly preceding `yield` and other nodes (#385)

+ used (#276)
+
+* *Black* now preserves line endings when formatting a file in place (#258)
+
+
+### 18.5b1
+
+* added `--pyi` (#249)
+
+* added `--py36` (#249)
+
+* Python grammar pickle caches are stored with the formatting caches, making
+ *Black* work in environments where site-packages is not user-writable (#192)
+
+* *Black* now enforces a PEP 257 empty line after a class-level docstring
+ (and/or fields) and the first method

+
+* fixed extra empty line between a class declaration and the first
+ method if no class docstring or fields are present (#219)

+
+### 18.5b0
+
+* call chains are now formatted according to the
+ [fluent interfaces](https://en.wikipedia.org/wiki/Fluent_interface)
+ style (#67)
+
+* data structure literals (tuples, lists, dictionaries, and sets) are
+ now also always exploded like imports when they don't fit in a single
+ line (#152)
+
+* slices are now formatted according to PEP 8 (#178)
+
+* parentheses are now also managed automatically on the right-hand side
+ of assignments and return statements (#140)
+

+ expressions (#148)

+ with a bracket and only contain a single operator (#177)
+
+* empty parentheses in a class definition are now removed (#145, #180)
+

+ on Python 3.6+ only code and Python 2.7+ code with the `unicode_literals`
+ future import (#188, #198, #199)
+
+* typing stub files (`.pyi`) are now formatted in a style that is consistent
+ with PEP 484 (#207, #210)

+ were used (#183)

+ parentheses in long assignments (#215)
+
+* fixed not splitting long from-imports with only a single name
+
+* fixed Python 3.6+ file discovery by also looking at function calls with
+ unpacking. This fixed non-deterministic formatting if trailing commas
+ where used both in function signatures with stars and function calls
+ with stars but the former would be reformatted to a single line.
+
+* fixed crash on dealing with optional parentheses (#193)
+
+* fixed "is", "is not", "in", and "not in" not considered operators for
+ splitting purposes

+
+### 18.4a4
+
+* don't populate the cache on `--check` (#175)

+ won't be reformatted again (#109)
+
+* `--check` and `--diff` are no longer mutually exclusive (#149)
