**Offband Meshcore 1.1.2-rc.3 is out** 📡

Big one this round:

🚫 **Block & mute** — block contacts or channel senders from just about anywhere (contacts, DMs, discovery, a channel message). Blocked stuff is hidden with a marker, name-only blocks upgrade to a real key when the sender shows up again, and there's a Blocked screen in Settings to manage it all. Syncs to the radio where firmware supports it.

🔔 **Per-channel notifications** — set each channel to all / mentions only / muted.

🗺️ **Path trace + topology** — width-matched traces, a topology readout, and a route builder that groups hops properly. Plus share/add channels by QR.

🔧 Fixes: USB no longer wedges some ESP32-C6 boards, DMs to a blocked contact actually stop sending, and more radios report GPS without flooding the link.
