This implementation increases parallel write capabilities of the eventstore.
Please have a look at the technical advisories: [05](https://zitadel.com/docs/support/advisory/a10005) and [06](https://zitadel.com/docs/support/advisory/a10006).
The implementation of eventstore.push is rewritten and stored events are migrated to a new table `eventstore.events2`.
If you are using cockroach: make sure that the database user of ZITADEL has `VIEWACTIVITY` grant. This is used to query events.
This PR adds support for the OIDC end_session_endpoint for V2 tokens. Sending an id_token_hint as parameter will directly terminate the underlying (SSO) session and all its tokens. Without this param, the user will be redirected to the Login UI, where he will able to choose if to logout.
This PR adds support for OAuth2 token revocation of V2 tokens.
Unlike with V1 tokens, it's now possible to revoke a token not only from the authorized client / client which the token was issued to, but rather from all trusted clients (audience)
This PR adds support for userinfo and introspection of V2 tokens. Further V2 access tokens and session tokens can be used for authentication on the ZITADEL API (like the current access tokens).
