Changelog

1.0.0

=====
pre-commit will now be following semver. Thanks to all
of the 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).
  • pre-commit clean now cleans up both the old and new directory.
  • If you were caching this directory in CI, you'll want to adjust the
    location.
  • 562 issue by nagromc.
  • 602 PR by asottile.
• A new configuration format for .pre-commit-config.yaml is introduced which
  will enable future development.
  • The new format has a top-level map instead of a top-level list. The
    new format puts the hook repositories in a repos key.
  • 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:

+repos:
 -   repo: https://github.com/pre-commit/pre-commit-hooks

     hooks:

• 414 issue by asottile.

Updating

• Run pre-commit migrate-config to convert .pre-commit-config.yaml to the
  new map format.
• Update any references from ~/.pre-commit to ~/.cache/pre-commit.
