+<p>Synapse now includes information indicating if a receipt applies to a thread when
+replicating it to other workers. This is a forwards- and backwards-incompatible
+change: v1.68 and workers cannot process receipts replicated by v1.69 workers, and
+vice versa.</p>
+<p>Once all workers are upgraded to v1.69 (or downgraded to v1.68), receipts
+replication will resume as normal.</p>
