Changelog

Release notes and version history for APRStac.

v0.2.4

July 2026

New Features

  • Added MeshCore Bluetooth and USB serial ports to the APRStac Android app.

Bug Fixes

  • Stations sharing a callsign but using different SSIDs can now message each other over MeshCore; previously each station discarded the other's traffic as its own echo.
  • APRStac Mobile: fixed a crash on first launch of a clean install.

v0.2.3

July 2026

New Features

  • Added MeshCore USB serial and Bluetooth LE ports to the desktop application.

v0.2.2

June 2026

New Features

  • Added a Quit button to the navigation menu to stop the application from the web interface.
  • APRStac Mobile now preserves your last map location across app restarts.
  • Centering the map on a station now uses a closer default zoom.
  • Stations reporting a status now show a colored indicator above their icon (red if any category is red, otherwise yellow, otherwise green).
  • Added a Send Status Report button (desktop and mobile) to manually transmit your status report when enabled in settings.
  • The message port selector now lists only enabled, running ports.
  • On the Status Report page, clicking a callsign opens that station on the map, and each row has a Message button.
  • New Dark/Light theme option in Settings → General. Dark stays the default; light mode suits bright or outdoor use.
  • Documented how repeaters are detected and listed on the documentation page.
  • Added an imperial/metric units option in Settings → General.
  • Added the ability to view a repeater's location on the map from the Repeaters page.
  • Added the ability to clear status reports from the Status Report page.

Bug Fixes

  • APRStac Mobile: returning to the map after switching tabs now keeps your last location instead of recentering on the default area.
  • Desktop: the map no longer resets zoom on each visit; it remembers your position and zoom when you navigate away.
  • APRStac Mobile: the message port selector now shows only running ports.
  • Fixed serial-connected Meshtastic devices failing to connect on Windows.
  • Fixed the wrong radio being selected for rigctld control; the Hamlib model numbers across the radio list were corrected.
  • Fixed Auto message routing so a reply goes out on the transport the message arrived on (for example APRS-IS) instead of falling back to RF only.

v0.2.1

June 2026

  • Fixed message delivery when operating as an IGate — messages addressed to another SSID of your callsign (e.g. a separate radio) are now relayed to that station instead of being captured and ACK'd locally
  • Added a Windows code-signing certificate (Authenticode) to reduce antivirus false positives on the Windows binary

v0.2.0

June 2026

  • Fixed a bug that caused duplicate messages to appear in the conversation history
  • Attempted a fix for a packet-formatting error that caused multiple ACKs to be sent for a single message
  • Added the ability to specify the APRS path used for messages in the Settings → General tab
  • Fixed an issue where receiving messages on a non-station SSID would spawn a separate message thread with yourself

v0.1.9

May 2026

  • Added TAK (Team Awareness Kit) port support (BETA) — bidirectional bridge between APRS and TAK Server using mTLS and Cursor on Target (CoT) events. Translates positions and messages in both directions, participates in digipeating like any other port, and auto-confirms message delivery when the TAK server accepts the event
  • Removed macOS builds — ongoing macOS support requires actual Apple hardware for testing, which is not currently available. Linux, Windows, Raspberry Pi (ARM), and Android remain fully supported

v0.1.8

April 2026

  • Fixed a bug which would cause thread to pause, and packets to stop being processed
  • Added Patreon link to the application

v0.1.7

April 2026

  • Third-party APRS packets (DTI }, common on APRS-IS from IGates) are now unwrapped so the original transmitting station — not the relay — is attributed on the map, in the station list, in packet stats, and in webhook output
  • Repeater extraction no longer misreads the source callsign's SSID as a frequency offset on wrapped packets
  • Wrapped weather reports are now captured into the weather database
  • APRS-IS-delivered messages addressed to your callsign will now be auto-ACK'd over RF (previously ignored)
  • New max_stations setting (default 10,000) bounds the stations table against runaway growth from high-volume APRS-IS feeds
  • IGate IS→RF no longer risks double-wrapping when an already-wrapped packet passes its filters

v0.1.6

April 2026

  • Added Statistics dashboard: Top 5 heard stations, per-port RX/TX volume charts, total RX over 24h, and Top 5 BBS users
  • Added source_callsign tracking on logged packets and a BBS connection history table

v0.1.5

April 2026

  • Fixed a bug which would repeat packets for the station's own callsign
  • Made it so the digipeater won't repeat packets destined for the station's email listen callsign if enabled
  • Adjusted some tips within the application settings

v0.1.4

April 2026

  • Added Reflector Server and Client ports for encrypted APRS packet sharing over TCP
  • Fixed Meshtastic connected mode bugs (frame parsing, packet integrity, timer adjustments)
  • Added version check on application start with update notification in sidebar

v0.1.3

April 2026

  • Added modern web GUI-based BBS interface when connecting to other APRStac BBS hosts
  • Added BBS private messaging system (send, receive, read, delete messages between users)
  • Added BBS welcome message setting (customizable per host, max 60 characters)
  • Added BBS beacon option to include callsigns with unread messages
  • Added BBS storage limits for postings and messages with automatic pruning
  • Added interactive prompts for bare BBS commands (P, S, R, O, D without arguments)
  • Added unread message count display on BBS connection welcome banner
  • Revamped BBS Postings and Messages web UI to tabular layout with filters and modals

v0.1.2

April 2026

  • Fixed a bug which could cause a loop with the IGate feature
  • Added Weather sensor chart data and statistics
  • Added Post to Discord Webhook feature under Notifications
  • Fixed a bug which would cause duplicate repeaters
  • Added weather display to map
  • Added database cleanup tasks and maximum allowed packet storage

v0.1.1

April 2026

  • Added VARA FM modem port type for connected-mode BBS and fileshare sessions
  • Fixed APRS-IS reporting — corrected SSID handling, packet formatting, and IGate qAR constructs for aprs.fi visibility
  • Added Radios tab in Settings for rigctld-based rig control (groundwork for future HF port support)
  • Added "Range - RF Only" map layer showing dotted lines from your station to each RF-heard station with distance labels

v0.1.0

  • Single binary with embedded web interface for Windows, Linux, and Raspberry Pi
  • Real-time Leaflet map with station tracking, grid overlays, and offline tile caching
  • 6 port types: KISS Serial, KISS TCP, APRS-IS, UDP Broadcast, Meshtastic TCP, Meshtastic Serial
