Documentation update

Retrieve the last import time from the database during health check.

This is useful to setup monitoring for meshview instances that are no longer receiving messages.

 The project serves as a real-time monitoring and diagnostic tool for the Meshtastic mesh network. It provides detailed insights into network activity, including message traffic, node positions, and telemetry data.
 
+### Version 3.0.5 — February 2026
+- **IMPORTANT:** the predicted coverage feature requires the extra `pyitm` dependency. If it is not installed, the coverage API will return 503.
+  - Ubuntu install (inside the venv): `./env/bin/pip install pyitm`
+- Coverage: predicted coverage overlay (Longley‑Rice area mode) with perimeter rendering and documentation.
+- Gateways: persistent gateway tracking (`is_mqtt_gateway`) and UI indicators in nodes, map popups, and stats.
+- Map UX: deterministic jitter for overlapping nodes; edges follow jittered positions.
+- Tooling: Meshtastic protobuf updater script with `--check` and `UPSTREAM_REV.txt` tracking.
+
+
+### Version 3.0.4 — Late January 2026
+- Database: multi‑DB support, PostgreSQL scripts, WAL config for SQLite, cleanup query timing fixes, removal of import time columns, and various time‑handling fixes.
+- UI/UX: extensive updates to node.html, nodelist.html, top.html, and packet.html (paging, stats, distance, status/favorites), plus net view changes to 12‑hour window.
+- API/logic: weekly mesh query fix, node list performance improvement, backwards‑compatibility and other bug fixes.
+- MQTT reader: configurable skip‑node list and secondary decryption keys.
+- Docs/ops: multiple documentation updates, updated site list, container workflow fixes/tests, README updates.
+
+### Version 3.0.2 — January 2026
+- Changes to the Database to will make it so that there is a need for space when updating to the latest. SQlite requires to rebuild the database when droping a column. ( we are droping some of the old columns) so make sure you have 1.2x the size of the db of space in your environment. Depending on how big your db is it would take a long time.

-# MeshView Docker Container
-
-> **Note:** This directory contains legacy Docker build files.
->
-> **For current Docker usage instructions, please see [README-Docker.md](../README-Docker.md) in the project root.**
-
-## Current Approach
-
-Pre-built container images are automatically built and published to GitHub Container Registry:
-
-```bash
-docker pull ghcr.io/pablorevilla-meshtastic/meshview:latest
-```
-
-See **[README-Docker.md](../README-Docker.md)** for:
-- Quick start instructions
-- Volume mount configuration
-- Docker Compose examples
-- Backup configuration
-- Troubleshooting
-
-## Legacy Build (Not Recommended)
-
-If you need to build your own image for development:
-
-```bash
-# From project root
-docker build -f Containerfile -t meshview:local .
-```
-
-The current Containerfile uses:
-- **Base Image**: `python:3.13-slim` (Debian-based)
-- **Build tool**: `uv` for fast dependency installation
-- **User**: Non-root user `app` (UID 10001)
-- **Exposed Port**: `8081`
-- **Volumes**: `/etc/meshview`, `/var/lib/meshview`, `/var/log/meshview`

+### How it works
+
+The coverage boundary is computed using the Longley-Rice / ITM **area mode**
+propagation model. Area mode estimates average path loss over generic terrain
+and does not use a terrain profile. This means it captures general distance
+effects, but **does not** account for terrain shadows, buildings, or foliage.
+
+### What you are seeing
+
+The UI draws a **perimeter** (not a heatmap) that represents the furthest
+distance where predicted signal strength is above a threshold (default
+`-120 dBm`). The model is run radially from the node in multiple directions,
+and the last point above the threshold forms the outline.
+
+### Key parameters
+
+- **Frequency**: default `907 MHz`
+- **Transmit power**: default `20 dBm`
+- **Antenna heights**: default `5 m` (TX) and `1.5 m` (RX)
+- **Reliability**: default `0.5` (median)
+- **Terrain irregularity**: default `90 m` (average terrain)
+
+### Limitations
+
+- No terrain or building data is used (area mode only).
+- Results are sensitive to power, height, and threshold.
+- Environmental factors can cause large real-world deviations.
