   wadamesh beta_18

   A unified release across all three boards — LilyGo T-Deck, Heltec V4 TFT, and the Tanmatsu (ESP32-P4).

   Flash it the easy way at https://flasher.wadamesh.com, or grab a bin below. On a normally-flashed device you can also update straight from Settings → About.

   ✨ New

   • Topographic maps — turn on Map → Options → Topographic map for terrain-relief tiles; OpenStreetMap stays the default. Thanks to @samuelcoustet for the proxy work (#52).
   • More emoji in the picker: ⚽ 🏈 🗿 🏳️‍⚧️.
   • Contacts sorting gained ascending/descending and a new Nearest first distance sort; the Discovered list gets the same sort options.
   • The Chats header is tidied up — add / mark-read / share grouped on the left, with a proper QR icon for sharing your contact.

   🐛 Fixed

   • The USB/PC companion connection no longer drops or throws "bad state" errors — also fixes repeater admin mode disconnecting and member-room login (#25, #54, #23).
   • Map edge/corner tiles now fill in as you pan instead of needing a manual reload (#20).
   • ~41 KB of memory reclaimed (moved a large buffer to PSRAM) — fixes the Heltec V4 rebooting when loading map tiles, and frees headroom on every board.
   • The map's Show link lines toggle now survives a reboot. Thanks to @Yazutsu (#61).
   • Settings category names fit on one line (no more mid-word splits); keyboard-nav toggling no longer jumps the list to the top (#45).
   • Heltec V4: node name no longer covers the clock (#47a). T-Deck: keyboard backlight no longer stuck on after flashing (#33).
   • More reliable crash reporting and fewer stray reboots while saving settings.
   • Tanmatsu: LoRa radio changes (frequency, etc.) now take effect immediately without a reboot, and the app's settings drive the radio.

   Everything from beta_16 (and the Tanmatsu's beta_17) is included.

   wadamesh beta_16 — Heltec V4 Expansion Kit support, European keyboards, and Wi-Fi updates (with rollback) are back.

   Flash or update at https://flasher.wadamesh.com, or grab it on-device under Settings → About if you're on a normally-flashed board.

   Heltec V4 Expansion Kit · thanks @samuelcoustet (#29)

   If you've got the sensor expansion board on a Heltec V4, there's finally a proper home for it: a dedicated Sensors tab (temperature, humidity, pressure, GPS and battery, each with a small history chart), an environment readout on the Home screen, and an on-device mesh console for poking at the radio directly. None of it shows up on a bare V4 — it only appears when a sensor board is actually detected, so nothing changes for everyone else.

   Worth being honest about this one: it was a real grind to land. It came in as a big pull request built against an old beta, so getting it in cleanly meant re-doing most of it by hand against current code and carefully gating every piece so it can't bloat or destabilise the T-Deck and Tanmatsu builds. The original work is @samuelcoustet's — thank you.

   European keyboards · thanks @samuelcoustet (#29)

   French, Dutch, German, Spanish and Italian layouts, both on-screen and on the T-Deck's physical keyboard. Choose one of those as your interface language and the matching layout is selected automatically.

   Wi-Fi updates are back — and you can roll back

   On a normally-flashed device (not installed through the Launcher), firmware updates over Wi-Fi return: Settings → About, no cable needed. New this round: Install a previous version — pick one of the last few betas and reinstall it over Wi-Fi, with an "are you sure?" first since it's a downgrade.

   Fixed · thanks @tun0

   • Closing a dialog no longer lets a scroll carry through to the page behind it (#50).
   • The contact action sheet no longer overflows the screen in landscape (#49).
   • The per-channel region field now shows your default region as the hint, instead of a generic placeholder (#48).
   • The status-bar clock no longer overlaps the node name on the V4.

   Everything from beta_15 is included. Thanks to @samuelcoustet and @tun0 for the contributions this round.

   wadamesh beta_15 ✨

   Two new touches, a couple of satisfying fixes, and one sensible default change.

   ✨ New

   • Amber power-save battery — idle power-saving now tints the status-bar battery amber, just like iPhone's Low Power Mode, instead of showing a separate moon icon. (T-Deck)
   • @-mention picker — type @ in the message box to pick a contact from a list and drop their name in. Thanks @robinshizuyo-dev (#42).

   🩹 Fixed

   • Lists stay put — closing a settings item, menu or chat no longer snaps the list back to the top; it stays where you left it. Thanks @ZorkaTheDog (#45).
   • App-sent messages appear on the device — a DM sent from the MeshCore companion app now also shows in the right conversation on-screen. Thanks @HonzaDandy (#46).
   • Typing reliability (T-Deck / Tanmatsu) — tapping a text field, even one that's already highlighted, starts typing right away, and the accent pop-up no longer interrupts typing outside of chats.
   • Cursor cue — the text cursor only appears when a field is actually ready for input, so it's a dependable "you can type now" hint.
   • Smoother map panning — tile rendering no longer trips the watchdog and reboots during heavy scrolling.

   ⚙️ Changed

   • Keyboard navigation is now OFF by default. Prefer driving the UI with the trackball / arrow keys? Turn it back on in Settings → Keyboard (your choice sticks until you change it). The Tanmatsu keeps it on, since it has no touchscreen.

   Everything from beta_14 is included.
