## Metadata

[Metadata](/docs/dev-guide/metadata/) gives you the ability to store key-value pairs against an object. Metadata is already available on [Events](/docs/api/v2/#tag--Events) and we've also added it to endpoints below.

- [Accounts](/docs/api/v2/#put/a/client_id)
- [Calendars](/docs/api/v2/#post-/calendars)

We’ve also created a new filter to make it easier to manage your key-value pairs. Use metadata_search with existing filters to make it easier to find your metadata. Read the [Metadata documentation](/docs/dev-guide/metadata/) page for more.

## API

- We’ve added a response category for Gmail labels.

## Platform

### Bug Fixes

- Fixed an issue with webhook delays.
- Fixed an issue with `account-cache` logs not appearing.
- Improved Neural API performance for recognizing text.

## Documentation

We’ve added a [Migrate Data Centers guide](/docs/dev-guide/platform/change-residency-region/) for supporting the transition between data regions.
