## Migrating your code style without ruining git blame
## NOTE: This is a beta product
-_Black_ is already [successfully used](#used-by) by many projects, small and big. It
-also sports a decent test suite. However, it is still very new. 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.

Also, as a temporary safety measure, _Black_ will check that the reformatted code still
produces a valid AST that is equivalent to the original. This slows it down. If you're
