explains it. The tl;dr is "it's like highway speed limits, we won't bother you if you
overdo it by a few km/h".
+**If you're looking for a minimal, black-compatible flake8 configuration:**

+```ini
+[flake8]
+max-line-length = 88
+extend-ignore = E203

### Empty lines
_Black_ avoids spurious vertical whitespace. This is in the spirit of PEP 8 which says
a set of comma-separated Python versions, optionally prefixed with `py`. For example,
to request code that is compatible with Python 3.5 and 3.6, set the header to
`py3.5,py3.6`.
+- `X-Diff`: corresponds to the `--diff` command line flag. If present, a diff of the
+ formats will be output.
If any of these headers are set to invalid values, `blackd` returns a `HTTP 400` error
response, mentioning the name of the problematic header in the message body.
- fixed feature detection for trailing commas in function definitions and call sites
(#763)
+- `# fmt: off`/`# fmt: on` comment pairs placed multiple times within the same block of
+ code now behave correctly (#1005)
+
- _Black_ no longer crashes on Windows machines with more than 61 cores (#838)
- _Black_ no longer crashes on standalone comments prepended with a backslash (#767)
- `blackd` now returns the version of _Black_ in the response headers (#1013)
+- `blackd` can now output the diff of formats on source code when the `X-Diff` header is
+ provided (#969)
+
### 19.3b0
- new option `--target-version` to control which Python versions _Black_-formatted code
