## Does Black have an API?
## Is Black safe to use?
-Yes, for the most part. _Black_ is strictly about formatting, nothing else. But because
-_Black_ is still in [beta](index.rst), some edges are still a bit rough. To combat
-issues, the equivalence of code after formatting is
+Yes. _Black_ is strictly about formatting, nothing else. Black strives to ensure that
+after formatting the AST is
[checked](the_black_code_style/current_style.md#ast-before-and-after-formatting) with
limited special cases where the code is allowed to differ. If issues are found, an error
is raised and the file is left untouched. Magical comments that influence linters and
## How stable is Black's style?
-Quite stable. _Black_ aims to enforce one style and one style only, with some room for
-pragmatism. However, _Black_ is still in beta so style changes are both planned and
-still proposed on the issue tracker. See
-[The Black Code Style](the_black_code_style/index.rst) for more details.

-## Does Black support Python 2?
+## Which Python versions does Black support?
-Support for formatting Python 2 code was removed in version 22.0.
+Currently the runtime requires Python 3.6-3.10. Formatting is supported for files
+containing syntax from Python 3.3 to 3.10. We promise to support at least all Python
+versions that have not reached their end of life. This is the case for both running
+_Black_ and formatting code.
