indentation level (like the arguments list and the docstring in the
example above).
+If a line of "from" imports cannot fit in the allotted length, it's always split
+into one per line. Imports tend to change often and this minimizes diffs, as well
+as enables readers of code to easily find which commit introduced a particular
+import. This exception also makes *Black* compatible with
+[isort](https://pypi.org/p/isort/). Use `multi_line_output=3` and
+`include_trailing_comma=True` in your isort config.

### Line length
*Black* avoids spurious vertical whitespace. This is in the spirit of
PEP 8 which says that in-function vertical whitespace should only be
-used sparingly. One exception is control flow statements: *Black* will
-always emit an extra empty line after ``return``, ``raise``, ``break``,
-``continue``, and ``yield``. This is to make changes in control flow
-more prominent to readers of your code.
+used sparingly.
*Black* will allow single empty lines inside functions, and single and
double empty lines on module level left by the original editors, except
It will also insert proper spacing before and after function definitions.
It's one line before and after inner functions and two lines before and
-after module-level functions. *Black* will put those empty lines also
-between the function definition and any standalone comments that
-immediately precede the given function. If you want to comment on the
-entire function, use a docstring or put a leading comment in the function
-body.
+after module-level functions. *Black* will not put empty lines between
+function/class definitions and standalone comments that immediately precede
+the given function/class.
### Trailing commas

This plugin **requires Vim 7.0+ built with Python 3.6+ support**. It
needs Python 3.6 to be able to run *Black* inside the Vim process which
that is pinned to the latest release on PyPI. If you'd rather run on
master, this is also an option.

+## Ignoring non-modified files
+
+*Black* remembers files it already formatted, unless the `--diff` flag is used or
+code is passed via standard input. This information is stored per-user. The exact
+location of the file depends on the black version and the system on which black
+is run. The file is non-portable. The standard location on common operating systems
+is:
+
+* Windows: `C:\\Users\<username>\AppData\Local\black\black\Cache\<version>\cache.<line-length>.pickle`
+* macOS: `/Users/<username>/Library/Caches/black/<version>/cache.<line-length>.pickle`
+* Linux: `/home/<username>/.cache/black/<version>/cache.<line-length>.pickle`

## Change Log
+### 18.4a4
+
+* don't populate the cache on `--check` (#175)
+
+
### 18.4a3
+* added a "cache"; files already reformatted that haven't changed on disk
+ won't be reformatted again (#109)
+
+* `--check` and `--diff` are no longer mutually exclusive (#149)
+
* generalized star expression handling, including double stars; this
fixes multiplication making expressions "unsafe" for trailing commas (#132)
-* fix parsing of complex expressions after star and double stars in
- function parameters (#2)
+* Black no longer enforces putting empty lines behind control flow statements
+ (#90)
+
+* Black now splits imports like "Mode 3 + trailing comma" of isort (#127)
+
+* fixed comment indentation when a standalone comment closes a block (#16, #32)
+
+* fixed standalone comments receiving extra empty lines if immediately preceding
+ a class, def, or decorator (#56, #154)
+
+* fixed `--diff` not showing entire path (#130)
+
+* fixed parsing of complex expressions after star and double stars in
+ function calls (#2)
+
+* fixed invalid splitting on comma in lambda arguments (#133)
+
+* fixed missing splits of ternary expressions (#141)
