 # Changelog
 
+## 0.2.7 (unreleased)

+- Adds safely framed matched-contact memories to inbound email, SMS, iMessage,
+  reaction, and voice context. Disable them with `gateway.contactMemories` or
+  `INKBOX_CONTACT_MEMORIES_ENABLED=false`.

 ## 0.1.1 (unreleased)
 
 - iMessage groups now match the rest of the plugin fleet: a group is one shared
