Encrypted sessions. New sessions are now end-to-end encrypted: chat, photos, voice messages, reports, marker names, the briefing and the session description can only be read by the session's players. • Invite players with the session's QR code or invite link. • Someone who types the code waits until a player lets them in, and you both check the same 6-digit code. • Map templates keep their marker names. Players need this version to join an encrypted session. Also: fixes and improvements.

• Welcome screen for new players: create a free account, continue as guest or log in. • SALTA and SITREP reports in chat; MEDEVAC follows the app's language. • Meshtastic radio: messages hop through other radios, steadier reconnects. • Map, chat and menu fixes.

• Invite links open TacSync directly when it's installed. • NATO markers: HQ option for units, names under the symbol, spaces kept while typing. • Members can leave a stopped session. • Map and menu fixes.

New TacSync app icon. • Your own position shows the moment GPS comes back, even after thick forest or with no mobile signal. • Small fixes.

Tacnav is now TacSync: same app, same sessions, new name. • Opens with no signal: your sessions, the map and saved offline maps work even when you restart the app in the field. • Fixed players being signed out mid-game and having to rejoin the session. • Faster reloading after a weak-signal spell.

• NATO map symbols: mark units, positions and objectives with standard military symbols. • Custom squads, with their short name shown inside each player dot. • MGRS grid on the map, and search by grid reference. • Session status: set the training to Standby, Ongoing or Stopped from the map. • Line of sight: see which ground is visible from any marker or teammate. • Height profile along drawn routes. • Sectors: show which way a teammate or marker is watching. • Tap a teammate in the member list to open their details. • Voice alerts speak distances in feet and miles when you use imperial units. • More reliable GPS sharing in the background, and many fixes.

• Meshtastic radios: pair a Meshtastic LoRa radio (Menu > Radio) and your team keeps sharing positions, markers, lines and chat where there is no mobile signal. Phones that do have signal pass everything on to the rest of the session. • Measure distance: long-press the map and pick Distance, or measure to any teammate or marker. Only you see these lines. • Tap a teammate on the map to see their details and actions. Marker and teammate cards are redesigned and follow light and dark mode. • Live positions stay fast in large sessions. • Fixes, including a first-launch error some new players saw.

• Invite QR codes now work for everyone: scanning one with the phone camera opens a page that launches Tacnav, or helps new teammates install it or join from a browser. • Notifications now arrive in your app language. • The map opens on your team and markers instead of a default location. • The live demo is now a quick preview: leave it and it's gone from your sessions. • Better battery life while sharing your position, plus stability fixes.

• Voice alerts: with headphones in, hear new markers, enemy sightings and injured teammates read out with their distance and direction, without looking at the screen. Turn it on in Map settings. • Works with bad signal: chat messages, photos, voice notes and markers are saved on your phone and sent automatically when you're back in range. The map, chat, photos and overlays stay available offline. • Clearer terrain: bold contour lines with elevation labels and relief shading, on every map style. • Simpler map settings: one map style picker (Mapbox, Esri, Lithuanian orthophoto, Sentinel-2, Dark, Outdoors, Streets) plus Labels and Topo lines switches. • Live rain radar overlay. • Sessions where you're alone open on the member list with a quick Invite button.

What's new: • Tap "+1" reactions on chat messages • "Seen by" indicator under your latest message • New Markers panel for one-tap jumps • Smoother teammate position tracking • Live update prompt for in-session improvements • Faster push delivery for chat, markers, and squad alerts
