What's New in 3.9.0

Key Mismatch Detection & Immediate Purge (#2243, closes #2227)

Proactively detects when a mesh node broadcasts a different public key than what's stored locally. When a mismatch is found, MeshMonitor can automatically purge the stale entry from your connected device to trigger re-discovery with the correct key.

• Mismatch detection: Compares mesh-received NodeInfo keys against stored keys in real-time
• Immediate Purge toggle: Optionally purge mismatched nodes on detection instead of going through the exchange retry cycle
• Activity log enhancements: Old/new key fragments and retry counts displayed in the Automation page activity log
• Security Tab: New Key Mismatch Events section showing mismatch history with status indicators
• Channel-based exchanges: NodeInfo exchanges for key repair are sent on the node's channel (not DM), since PKI-encrypted DMs fail when keys are mismatched
• Supports all three database backends (SQLite, PostgreSQL, MySQL)

Map Visualization UI Overhaul (#2237)

Major refresh of the map interface with improved usability and visual consistency. Thanks to @NearlCrews for his work on this!

• Consolidated map legend: Merged position history legend into a single collapsible panel showing hop colors, link types, SNR quality, and position history gradient
• Node hover isolation: Hovering a node marker dims unrelated route/neighbor lines to trace paths per node
• Zoom-adaptive filtering: Poor/unknown SNR route segments and neighbor lines auto-hide at low zoom levels
• Standardized overlay panel styling: All panels now share consistent Catppuccin-themed styling
• Tileset selector redesign: Responsive 3-column grid layout replacing the old horizontal row
• Improved touch detection: Uses CSS media queries for accurate laptop+touchscreen handling

Bug Fixes

• Node uptime not showing on PostgreSQL/MySQL backends (#2242)
• Draggable overlay gets stuck off-screen on window resize (#2241)
• Map preferences not saving on PostgreSQL/MySQL backends (#2239)
