+## Clarification on Permission Splits for Expressions and Events
+
+#### December 15, 2023
+
+> info
+> The existing behavior for `MANAGE_GUILD_EXPRESSIONS` and `MANAGE_EVENTS` will **not be changing**. These permissions will continue to allow your bot users to create, update and delete expressions/events. No action will be needed if you plan to continue using these permissions.
+
+To support added controls for expressions and events, new [permissions](#DOCS_TOPICS_PERMISSIONS/permissions) were added for users and roles in July 2023:
+
+* `CREATE_GUILD_EXPRESSIONS`: `1 << 43`
+* `CREATE_EVENTS`: `1 << 44`
+
+These allow for creating new expressions and events, as well as editing and deleting those created by the current user.  
+
+> warn
+> These were rolled out in July 2023 to users and roles and have been added to our developer documentation but **are not yet available to app developers**. We will share an update here when these new permissions are available in your apps.

-* `CREATE_EVENTS`: `1 << 44`
-
-These allow for creating new expressions/events, as well as editing and deleting those created by the current user.
