 ## Unreleased
 
+User profiles and the user and preference webhooks; they need an Anikeen ID release that supports
+them.
+
+### Added
+
+- Profile updates with the user's token (scope `user`): `updateProfile()` (name, username, email;
+  a new email address waits for the user's confirmation), `uploadAvatar()` and `removeAvatar()` on
+  `Billable`. They return the updated profile and clear the cached `getUserData()`.
+- Reading a connected user's profile by ID for trusted apps: `findUserById()` (`null` for an
+  unknown, deleted or unconnected user).
+- `Resources\User` with `emailVerified()`, `version()` (`profile_version` or a webhook's
+  `version`), `pendingEmail()` and `pendingEmailExpiresAt()`; it also reads the object of a
+  `user.updated` event.
+- `ValidationFailedException` (a subclass of `ApiException`) for 422 responses, with
+  `errorCodes()`, `errorCodeFor()`, `hasErrorCode()` and `errors()`; catching `ApiException` keeps
+  working.
+- `AnikeenId::requestMultipart()` for file uploads.
+- Opt-in webhook events `user.updated`, `user.deleted` and `preference.updated`
+  (`EventType::USER_UPDATED`, `USER_DELETED`, `PREFERENCE_UPDATED`).
+
+## 3.4.0-beta.1 (2026-11-06)
+
 Preferences, charges and the billing limit; they need an Anikeen ID release that supports them.
