## Offband Meshcore 1.1.2-rc.3

This release brings a full **block / mute system**, richer **path tracing and topology**, and **per-channel notification control**, along with a batch of connectivity and UX fixes. It combines the rc.2 and rc.3 closed-test builds.

### Blocking and muting
You can now block a contact or a channel sender from contacts, DMs, discovery, or directly from a channel message. Blocked DMs and adverts are suppressed with a visible marker, a name-only block is promoted to the sender's public key the next time they advert or DM you, and stale blocks age out after 30 days. Everything is managed from Settings → Blocked, and where the radio's firmware supports it, your block list syncs to the device on connect.

### Notifications, your way
Each channel gets a three-way notification selector — all messages, mentions only, or muted — applied right at the notification gate and remembered per channel.

### Path tracing and topology
Path traces are now width-matched to the mesh, with a topology readout and a route-builder that groups hops the way the network actually addresses them rather than as raw bytes. Channel QR codes let you share a channel or add one by scanning, using the reference-app format.

### Fixes worth calling out
- USB no longer wedges ESP32-C6 boards: the open-time DTR pulse is gated by device type, so it only fires where it's needed.
- Outgoing DMs to a blocked contact are dropped at the send path.
- GPS refresh falls back to stock-firmware telemetry when the fork-specific query isn't available, so more radios report position without flooding the link.
