v1.2.1

Added

• Auto-reconnect — an optional toggle that automatically retries the last
  device after an unexpected drop, before the disconnect alarm. Shown only
  where it can actually work (not for Bluetooth in a mobile browser).
• Nicer packet sound — a pleasant bell whose pitch still tracks signal
  strength, plus a new "disconnect only" sound mode. The disconnect alarm now
  sounds on every unexpected drop.

Changed

• Location now starts automatically when you connect (Android) — no need to
  tap the 3D map's "Enable location" button anymore.
• Steadier location on the 3D map — occasional GPS jumps (sudden ~200 m
  hops) are filtered out.
• 3D map zooms in to street level even on large maps, and deep zoom is
  smoother.
• 3D camera framing — "Center on me" no longer jerks at the end of its move,
  and repeaters are framed with a little headroom above them.

Fixed

• 2D charts could stop updating with Display set to All, until you switched
  the Display window and back.
• Help (?) tooltips could appear away from their icon.
• Seen Repeaters now shows the true last RSSI/SNR, not a rounded/averaged value.
• Received Packets always lists every repeater as a column, not only the ones on
  the current page.
• 3D map selection no longer clears itself on its own.
• 3D map tiles no longer flicker while panning or zooming.
• Footer text now has proper contrast in light mode.

v1.2.0

Added

• Zoomable 2D signal charts — wheel or pinch to zoom the time axis, drag across a region to zoom in, drag/Shift+wheel to pan. Both charts stay aligned; double-click or Reset zoom to restore.
• Full capture history is now kept on disk, not just in memory — "Auto-remove: Never" keeps the whole session without slowing down or running out of memory, your data survives a reload or crash (it offers to resume on launch), every view is consistent across the Display window, and CSV export covers the complete history.
• More 3D map styles — CARTO (Dark Matter, Positron, Voyager, +no-label variants), Esri (Dark/Light Gray Canvas and satellite), more OpenStreetMap flavours, and a None (no map) option. In dark mode the area around the map is now black.

Changed

• Longer history durations — Auto-remove and Display now offer 3 h and 12 h (10 min and 30 min were removed).
• The 3D map's "Cluster radius" setting is gone — nearby points are grouped automatically based on zoom, so there's nothing to tune.

Fixed

• The Android app no longer freezes on a blank screen after running for hours, and recovers on its own if the system reclaims it in the background.
• Packets captured before location was turned on are no longer placed at your current location on the 3D map — position-less points aren't shown; CSV import likewise never assigns the current location to rows that have none.
• Connecting to a saved Bluetooth device while Bluetooth is off now prompts you to turn it on instead of silently never connecting.
• A Bluetooth device you renamed after saving it now connects under, and is re-saved with, its new name.
• Better light/dark readability — the map's location-status text, the 3D-map fullscreen button, the packet detail panel and the page footer are now legible in both themes; map buttons no longer look stuck-pressed after a tap.

v1.1.0

Added

• Connect over USB — plug a companion radio in with a USB cable instead of
  using Bluetooth. Devices you've connected to before show up as buttons for
  one-tap reconnecting.
• Repeater support — you can now plug a MeshCore repeater into USB,
  not just a companion radio; the app detects which kind it is on its own. With
  special logging firmware it shows full detail for every packet; with normal
  firmware it shows what it can read from the repeater's logs.
• Connect over WiFi (Android app only) — reach a WiFi companion over your
  network by typing in its IP address. Web browsers can't do this, so it works
  only in the Android app.
• Android app niceties — it now shows the current status in the phone's
  notification bar (with a speaker icon while beep alerts are on, and a "paused"
  marker when capture is stopped), opens web links in your normal browser, and
  closes pop-ups when you press Back.
• 3D map additions:
  • optionally show your own device's location on the map (off by default —
    while on it keeps asking the device for its position, which can drain the
    battery faster, so leave it off when you don't need it);
  • a Center on me button that recentres the map and then follows you as
    you move;
  • pin repeaters to the map and point the camera at one;
  • while capturing, the map keeps the area around you loaded so you don't drift
    off the edge.
• Disconnect warning — a clear full-screen alert if the connection drops
  unexpectedly (cable unplugged, device reset, out of range). It stays quiet
  when you disconnect on purpose.

Changed

• Tidier header — the connect/disconnect buttons and the status are grouped
  into one colour-coded box (red when disconnected, green when connected).
• Sound is easier to notice — when the beep-on-each-packet sound is turned
  on, its control turns yellow so you can see at a glance that it's on.
• Clearer repeater colors — brighter and easier to tell apart.

Fixed

• Trace packets now show the correct route (they used to show the wrong path).
• Your contacts list no longer sometimes fails to finish loading.
• The 3D map's "Enable location" button no longer freezes when your phone's
  location is switched off — it works again once you turn location back on.
• The same Bluetooth device no longer shows up several times in your list of
  saved devices.
• The 3D map's fullscreen button now works in the Android app (it did nothing
  there before).

Plus lots of smaller improvements throughout.
