 All notable changes to Void 2.0 are documented here.
 Format: [Keep a Changelog](https://keepachangelog.com).
 
+## 2.1.2 — Edit known network devices
+- **Edit devices in the Network·Devices band** (`public/views/devices_band.js`): known tiles get a ✎ edit affordance — rename, re-group, or delete a device (PATCH/DELETE `/api/devices/:mac`, which already existed). Previously a device could only be named when first promoted from Discovered.
+
 ## 2.1.1 — OBD2 Apps rail placeholder
 - **OBD2 Apps rail item** (`public/views/obd2.js`, router/app/sidebar): a placeholder launchpad under **Apps** for the parked OBD2 Telemetry project — links to the project + tasks and the research/wiki page. Swap to an `embedView` once a records UI (LubeLogger/Tracktor) is deployed.
