 ## [Unreleased]
 
+## [3.0.0] - 2026-10-25
+
+This release is a major version because the error contract changed: every public
+method that is given a missing or invalid argument now rejects, where 2.1.11
+logged with `console.error` and resolved to `undefined`. Code that relied on the
+old silent behaviour needs a `catch` before upgrading. See **Changed** below.

 ### Added
 
 - `validateEmail` accepts `activityData`, `verifyPlus`, and `method: "POST"` (form-encoded `POST /v2/validate`). `timeout` is still optional and must be from 3 to 60 seconds.
