### Usage
- [Usage and Configuration](https://black.readthedocs.io/en/stable/usage_and_configuration/index.html)
-### NOTE: This is a beta product
-
_Black_ is already [successfully used](https://github.com/psf/black#used-by) by many
-projects, small and big. Black has a comprehensive test suite, with efficient parallel
-tests, and our own auto formatting and parallel Continuous Integration runner. However,
-_Black_ is still beta. Things will probably be wonky for a while. This is made explicit
-by the "Beta" trove classifier, as well as by the "b" in the version number. What this
-means for you is that **until the formatter becomes stable, you should expect some
-formatting to change in the future**. That being said, no drastic stylistic changes are
-planned, mostly responses to bug reports.

+tests, and our own auto formatting and parallel Continuous Integration runner. Now that
+we have become stable, you should not expect large formatting to changes in the future.
+Stylistic changes will mostly be responses to bug reports and support for new Python
+syntax. For more information please refer to the
+[The Black Code Style](docs/the_black_code_style/index.rst).
Also, as a safety measure which slows down processing, _Black_ will check that the
reformatted code still produces a valid AST that is effectively equivalent to the

place. Style configuration options are deliberately limited and rarely added. It doesn't
-take previous formatting into account (see [Pragmatism](#pragmatism) for exceptions).

Our documentation covers the current _Black_ code style, but planned changes to it are
also documented. They're both worth taking a look:
- [The _Black_ Code Style: Current style](https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html)
- [The _Black_ Code Style: Future style](https://black.readthedocs.io/en/stable/the_black_code_style/future_style.html)
+Changes to the _Black_ code style are bound by the Stability Policy:
