of the [contributors](https://github.com/pre-commit/pre-commit/graphs/contributors)
that have helped us get this far!

Features

- pre-commit's cache directory has moved from `~/.pre-commit` to
`$XDG_CACHE_HOME/pre-commit` (usually `~/.cache/pre-commit`).

 - Old list-based configurations will continue to be supported.
 - A command `pre-commit migrate-config` has been introduced to "upgrade"
   the configuration format to the new map-based configuration.
 - `pre-commit autoupdate` now automatically calls `migrate-config`.
 - In a later release, list-based configurations will issue a deprecation
   warning.
 - An example diff for upgrading a configuration:

 diff
 +repos:
  -   repo: https://github.com/pre-commit/pre-commit-hooks
      sha: v0.9.2
      hooks:
