 Sydent 2.6.0 (2023-11-20)
 =========================
 
+Sydent will soon be forked by Element under an AGPLv3.0 licence (with CLA, for
+proprietary dual licensing). We expect this to be the last release of Sydent
+under the current Apache 2 licence.
+
+You can read more about this here:

+- https://element.io/blog/element-to-adopt-agplv3/
+
+The Matrix.org Foundation copy of the project will be archived. Any changes needed
+by server administrators will be communicated in Sydent's changelog, but we are
+striving to make this as seamless as possible.
