 ### Changed
 
+- Inline `_InviteMetadata` fields into `IncompleteInvite` and remove the now-unused
+  `_InviteMetadata` TypedDict.
+  ([#3313](https://github.com/Pycord-Development/pycord/pull/3313))
+
 ### Fixed
 
+- Fix `Invite.code` handling when `None` (from `VanityInvitePayload`). `__str__` falls
+  back to `""`, `.url` and all code-dependent methods raise `ValueError`, and
+  `Invite.code` is typed as `str | None`.
+  ([#3313](https://github.com/Pycord-Development/pycord/pull/3313))
 - Fix an attribute error in `RoleColours.is_holographic()` when `secondary` or
   `tertiary` is `None`.
