+## Unreleased
+
+* [Bug fix] Drop support for retiring users in the [Open edX E-Commerce Service](https://github.com/openedx/ecommerce).
+  Per the discussion in [Issue #36](https://github.com/hastexo/tutor-contrib-retirement/issues/36), account retirement for the E-Commerce Service "will never" work and "has never" worked, thus this is not a breaking change.
+
 ## Version 3.3.0 (2024-04-05)
 
 * [Enhancement] Support Python 3.12.
