intercept/CHANGELOG.md

Changelog

All notable changes to iNTERCEPT will be documented in this file.

[2.26.11] - 2026-03-14

Fixed

• APRS map ignores configured observer position — The APRS map always fell back to the centre of the US (39.8°N, 98.6°W) when no live GPS fix was available, ignoring the observer position configured in .env (INTERCEPT_DEFAULT_LAT / INTERCEPT_DEFAULT_LON). Now seeds the APRS user location from the shared observer location on page load, so the map centres correctly and distance calculations work. (#193)

---

[2.26.10] - 2026-03-14

Fixed

• APRS stop timeout and inverted SDR device status — The APRS stop endpoint terminated two processes sequentially (up to 4s) while the frontend timed out at 2.2s, causing console errors and the SDR status panel to show stale state (active after stop, idle during use). Now releases the SDR device immediately and terminates processes in a background thread so the response returns instantly. (#194)

---

[2.26.9] - 2026-03-14

Fixed

• ADS-B bias-t support for RTL-SDR Blog V4 — When dump1090 lacks native --enable-biast support, the system now falls back to rtl_biast (from RTL-SDR Blog drivers) to enable bias-t power before starting dump1090. The Blog V4's built-in LNA requires bias-t to receive ADS-B signals. (#195)

---

[2.26.8] - 2026-03-14

Fixed

• acarsdec build failure on macOS — HOST_NAME_MAX is Linux-specific (<limits.h>) and undefined on macOS, causing 3 compile errors in acarsdec.c. Now patched with #define HOST_NAME_MAX 255 before building. Also fixed deprecated -Ofast flag warning on all macOS architectures (was only patched for arm64). (#187)

---

[2.26.7] - 2026-03-14

Fixed

• Health check SDR detection on macOS — timeout (GNU coreutils) is not available on macOS, causing rtl_test to silently fail and report "No RTL-SDR device found" even when one is connected. Now tries timeout, then gtimeout (Homebrew coreutils), then falls back to a background process with manual kill. (#188)

---

[2.26.6] - 2026-03-14

Fixed

• Oversized branded 'i' logo on dashboards — .logo span { display: inline } in dashboard CSS had higher specificity (0,1,1) than .brand-i { display: inline-block } (0,1,0), forcing the branded "i" SVG to render as inline which ignores width/height. Added .logo .brand-i selector (0,2,0) to retain inline-block display. (#189)

---

[2.26.5] - 2026-03-14

Fixed

• Database errors crash entire UI — get_setting() now catches sqlite3.OperationalError and returns the default value instead of propagating the exception. Previously, if the database was inaccessible (e.g. root-owned instance/ directory from running with sudo), the inject_offline_settings context processor would crash every page render with a 500 Internal Server Error. (#190)

---

[2.26.4] - 2026-03-14

Fixed

• Environment Configurator crash — read_env_var() crashed with "Setup failed at line 2333" when .env existed but didn't contain the variable being looked up. grep returned exit code 1 (no match), which pipefail propagated and set -e turned into a fatal error. Fixed by appending || true to the pipeline. (#191)

---

[2.26.3] - 2026-03-13

Fixed

• SatDump AVX2 crash — SatDump now compiles with -march=x86-64 on x86_64 platforms (Docker and setup.sh), preventing "Illegal instruction" crashes on CPUs without AVX2. SIMD plugins still use runtime detection for acceleration on capable hardware. (#185)

---

[2.26.2] - 2026-03-13

Fixed

• Docker startup crash — .dockerignore excluded the entire data/ directory, which is now a Python package (data.oui, data.patterns, data.satellites). Caused ModuleNotFoundError: No module named 'data.oui' on container startup. Fixed by only excluding non-code files from data/.

---

[2.26.1] - 2026-03-13

Fixed

• Default admin credentials — Default ADMIN_PASSWORD changed from empty string to admin, matching the README documentation (admin:admin)
• Config credential sync — Admin password changes in config.py or via INTERCEPT_ADMIN_PASSWORD env var now sync to the database on restart, without needing to delete the DB

---

[2.26.0] - 2026-03-13

Fixed

• SSE fanout crash - _run_fanout daemon thread no longer crashes with AttributeError: 'NoneType' object has no attribute 'get' when source queue becomes None during interpreter shutdown
• Branded logo FOUC - Added inline width/height to branded "i" SVG elements across 10 templates to prevent oversized rendering before CSS loads; refresh no longer needed

---

Added

• Mobile UX polish - Improved touch targets, code overflow handling, and responsive layouts

Fixed

---

[2.24.0] - 2026-03-10

Added

• WiFi Locate Mode - Locate WiFi access points by BSSID with real-time signal meter, distance estimation, RSSI chart, and audio proximity tones. Hand-off from WiFi detail drawer, environment presets (Free Space/Outdoor/Indoor), and signal-lost detection.

Changed

• Mobile navigation bar reorganized into labeled groups (SIG, TRK, SPC, WIFI, INTEL, SYS) for better usability
• flask-limiter made optional — rate limiting degrades gracefully if package is missing

Added

---

[2.22.3] - 2026-02-23

Fixed

• Waterfall control panel rendered as unstyled text for up to 20 seconds on first visit — CSS is now loaded eagerly with the rest of the page assets
• WebSDR globe failed to render on first page load — initialization now waits for a layout frame before mounting the WebGL renderer, ensuring the container has non-zero dimensions
• Waterfall monitor audio took minutes to start — _waitForPlayback now only reports success on actual audio playback (playing/timeupdate), not from the WAV header alone (loadeddata/canplay)
• Waterfall monitor could not be stopped — stopMonitor() now pauses audio and updates the UI immediately instead of waiting for the backend stop request (which blocked for 1+ seconds during SDR process cleanup)
• Stopping the waterfall no longer shows a stale "WebSocket closed before ready" message — the onclose handler now detects intentional closes

---
