 ## v1.7.117-alpha (2026-07-29)
 
 - Flash your LoRa radio from inside the app. The Mesh page now has a "Flash LoRa" button that opens a guided flow: pick the firmware family (MeshCore, Meshtastic, or Reticulum RNode) and your board, and the node downloads the latest release and flashes it with live progress — no external flasher website, no cables to a computer. The same flow appears when a freshly plugged-in radio is detected, and a long list of flashing pitfalls was fixed along the way: radios no longer boot-loop after a flash, failures show the real error instead of silently bouncing back, wedged flash jobs can't get stuck forever, and board auto-detection no longer misidentifies Heltec boards.
+- Every Archipelago node now acts as a Reticulum relay. Nodes forward mesh traffic and re-broadcast peer announcements, so two radios that can't hear each other directly can still discover and message each other through any Archipelago node in between — your nodes become infrastructure for the whole neighbourhood mesh, including non-Archipelago apps like Sideband.
 - Reticulum (RNode) radios are now first-class mesh citizens. Radios are reliably detected on node startup (a boot-timing race used to leave them unclaimed), settings changes apply live without a restart, your node's name propagates over the Reticulum network so other apps like Sideband see it properly, and a crashed Reticulum daemon is detected and restarted automatically. Photo and file attachments sent over Reticulum now actually arrive — four separate delivery bugs were found and fixed, verified end-to-end over real radio hardware.
 - Messages to contacts that exist on both the internet mesh and a LoRa radio now prefer the radio when it's live, and attachments follow the same path — so co-located nodes talk over the air even when the internet path exists.
 - Mesh chat polish: each message in the image viewer shows which transport carried it, a new hop-route view shows the path a message took, reactions moved into a tidy dropdown, and read-tracking now reflects what you've actually seen. The Refresh and Broadcast buttons give real feedback, and the radio-setup modal shows honest probe progress instead of freezing.
