# PostHog Migration Guide

## Upgrading to 1.0.0

Version 1.0.0 introduces a single change to the `events` stream. It corrects the casting of the `event` field datatype, which was incorrectly labeled as a `json` object. Now, it is accurately attributed only as a `string`, as outlined in the PostHog [documentation](https://posthog.com/docs/api/events). To apply this change, refresh the schema for the 'events' stream and reset your data.
