Jira Cloud REST API privacy updates and migration guide

Is there a doc on how Webhooks are changing? (I likely missed it.)

i.e. When an issue updates, we get a web hook that includes PII (username & user_key) in URL params.

/jira/v1/webhooks/updated?lic=none\u0026user_id=first.last\u0026user_key=first.last

I would guess those will change to accountId but wanted to confirm. Thanks!

Edit: This is with "gdpr": true in apiMigrations.
