-        Web Keys in ZITADEL are used to sign and verify JSON Web Tokens (JWT).
-        ID tokens are created, signed and returned by ZITADEL when a OpenID connect (OIDC) or OAuth2 authorization flow completes and a user is authenticated.
-        Based on customer and community feedback, we've updated our key management system. You now have full manual control over key generation and rotation, instead of the previous automatic process.
+        This API enables you to manage custom executions and targets—formerly known as actions—across your entire ZITADEL instance.
+        With Actions V2, you gain significantly more flexibility to tailor ZITADEL’s behavior compared to previous versions.
+        Actions are now available instance-wide, eliminating the need to configure them for each organization individually.
+        ZITADEL no longer restricts the implementation language, tooling, or runtime for action executions.
+        Instead, you define external endpoints that are called by ZITADEL and maintained by you.

-        ZITADEL supports the use of a caches to speed up the lookup of frequently needed objects.
-        As opposed to HTTP caches which might reside between ZITADEL and end-user applications, the cache build into ZITADEL uses active invalidation when an object gets updated.
-        Another difference is that HTTP caches only cache the result of a complete request and the built-in cache stores objects needed for the internal business logic.
-        For example, each request made to ZITADEL needs to retrieve and set instance information in middleware.
