### Removed

- Handling of client-provided channel identifiers. **BREAKING CHANGE**

Please make sure that you have changed your channel `disconnected` method to pass channel instance to GraphQL-AnyCable's `delete_channel_subscriptions` method.
See [release notes for version 1.1.0](https://github.com/anycable/graphql-anycable/releases/tag/v1.1.0) for details.

- Handling of pre-1.0 subscriptions data.

If you're still using version 0.5 or below, please upgrade to 1.0 or 1.1 first with `handle_legacy_subscriptions` setting enabled.
