    Highlights

    Meshtastic 2.8 support

    • Added support for Meshtastic firmware 2.8.0 and newer.

    • Implemented compact initial node database loading followed by background position and telemetry replay.

    • Preserved the legacy connection flow for older firmware versions.

    • Added firmware compatibility validation for device settings.

    • Added support for new Meshtastic 2.8 features:

      • Mesh Beacon;
      • packet signature policies;
      • new protobuf fields;
      • repeated configuration fields.
    • Added validation for legal region and LoRa preset combinations.

    • Added licensed-operator mode validation for applicable regions.

    • Added Mesh Beacon limits for message length, interval, and channel index.

    • Limited long node names to 24 UTF-8 bytes on Meshtastic 2.8.

    • The deprecated UA_868 region can no longer be selected for new configurations.

    • Improved configuration snapshot import, export, and editing.

    • Updated the built-in documentation in English, Russian, and German.

    Maps and OpenStreetMap policy compliance

    • Removed bulk downloading of selected areas from tile.openstreetmap.org.

    • Removed background prefetching and offline tile downloads.

    • MeshApp now requests only tiles visible in the current map viewport.

    • Queued requests are discarded when their tiles leave the viewport.

    • Limited concurrent tile requests to two.

    • Added HTTP/2 support.

    • Implemented HTTP-compliant caching:

      • Cache-Control;
      • Expires;
      • ETag;
      • Last-Modified;
      • conditional requests;
      • 304 Not Modified handling;
      • a seven-day fallback cache lifetime.
    • Added support for configuring an alternative interactive tile provider.

    • Added an identifiable User-Agent

    • Preserved support for connecting a pre-existing tile directory in z/x/y.png|jpg|jpeg format for offline use.

    • MeshApp does not download or update connected offline directories through OpenStreetMap servers.

    For offline maps, use tiles obtained from a provider whose terms explicitly permit offline use.

    Bluetooth LE

    • Improved PIN entry handling during device pairing.
    • Stale PIN dialogs are now dismissed when a new request arrives.
    • The pairing dialog closes automatically after disconnection, connection failure, or completion.
    • Prevented duplicate handling of completed pairing requests.
    • Improved native BLE resource cleanup after disconnection.
    • Improved pairing behavior in graphical and terminal modes.

    Chats and notifications

    • Notification preferences are now applied independently to each remote RPC connection.
    • Muted channels and direct-message conversations no longer produce remote system notifications.
    • The muted state is applied correctly to remote chat snapshots.
    • Improved chat data transfer over RPC.

    • Fixed the Linux system tray icon.
    • Added complete Ayatana AppIndicator integration for Flatpak.
    • Fixed the application icon in DEB packages.
    • Added a correct desktop entry for Linux packages.
    • Fixed emoji rendering in Linux window titles.
    • Improved window title and icon updates through native Linux APIs.
    • Fixed connection form flickering during list updates.
    • Stabilized transitions between connection states.

    Startup and packaging

    • Enabled native access for regular, packaged, and self-update launch paths.
    • MeshApp now automatically restarts with the required JVM permissions when they are missing.
    • Command-line arguments are preserved during this restart.
    • Updated Gradle to 9.6.1.
    • Updated GraalVM Build Tools to 1.1.4.
    • Reorganized and documented the build configuration.
    • Improved user-preference isolation in tests.
