**Session key inconsistency across Gunicorn workers** (`app.py`). Without
**Gunicorn workers crashing on startup when PostgreSQL is not yet ready**

v2.56.1

Fixed (2)

**Web stream stall after extended runtime** (`icecast_output.py`) — The source-timeout restart check was gated on the internal buffer being non-empty (`and buffer`). When the audio source stopped supplying data the buffer drained to zero, causing the check to silently skip and leaving a stalled FFmpeg process running indefinitely. The erroneous guard has been removed so the timeout fires correctly regardless of buffer state.
**RBDS decoding never locking** (`demodulation.py`) — Two related bugs prevented reliable RBDS carrier lock:

v2.56.0

Changed (7)

**Ambient background gradient** — All pages now display a subtle two-orb radial-gradient overlay fixed to the viewport. The gradient is derived from the active theme's `--primary-color` and `--secondary-color` variables, so it automatically adapts across all 20 built-in themes.
**Admin card headers** — Replaced the flat `var(--bg-color)` fill with a theme-aware gradient tint (`color-mix` at low opacity against `--surface-color`), giving every section card a subtle accent without obscuring form content.
**Admin header banner** — Replaced hardcoded `#667eea / #764ba2` hex values with `var(--primary-color)` / `var(--secondary-color)` so the banner matches the chosen theme. Added a shimmer highlight overlay and a stronger box-shadow for depth.
**Admin stat cards** — Replaced hardcoded indigo/purple gradient with theme-aware `var(--primary-color)` → `var(--secondary-color)` gradient. Hover shadow also now uses `color-mix` on the theme primary rather than a hardcoded RGBA.
**Admin modal headers** — Replaced the hardcoded red gradient with the theme primary→secondary gradient to align with the rest of the UI.
**Manage-card headers** — Applied the same subtle gradient tint treatment as the main card headers for visual consistency.
**Form focus glow** — Replaced hardcoded `rgba(102, 126, 234, 0.2)` focus ring with `color-mix(in srgb, var(--primary-color) 20%, transparent)` so the focus state reflects the active theme color.

v2.55.0

Added (1)

**Unified Settings hub page** (`/settings`) — All settings sections (Configuration, Network, Hardware, Security & Access) are now presented as a single card-based overview page, making it much easier to discover and navigate to any setting without hunting through nested dropdown menus.

Changed (1)

**Settings navbar entry simplified** — The Settings dropdown (which previously contained 15+ nested links across four sections) is replaced by a single "Settings" link that navigates directly to the new unified `/settings` hub page, reducing navbar visual complexity.

v2.54.1

Changed (3)

**Merged Hardware dropdown into Settings** - The Hardware navigation item has been removed as a standalone top-level dropdown. All hardware-related links (SDR Receivers, Audio Streams, Audio Archives, Hardware Settings, GPIO & Relays, Zigbee) are now organized under a new "Hardware" section within the Settings dropdown, reducing top-level navigation from 7 to 6 items.
**Moved Audio Health to Monitor** - Audio Health dashboard link moved from Tools > Observability to Monitor > Radio Monitoring, where it logically belongs alongside other audio/radio monitoring links.
**Removed duplicate Alert Statistics from Tools** - The `/stats` link in Tools > Analytics & Reporting has been removed since Statistics is already accessible from the Monitor dropdown.

v2.54.0

Added (10)

**`POST /api/led/set_time_format` endpoint** (v2.54.0)
Accepts `time_format` ("TIME_12H" or "TIME_24H"), `color`, and `font` parameters.
Calls the LED sign controller to apply the selected 12-hour or 24-hour time format, then sends the current time as a two-line message ("CURRENT TIME" / formatted time string) to the sign.
Records the sent message in the `led_messages` database table.
Files: `webapp/routes_led.py`
**`POST /api/led/set_date_format` endpoint** (v2.54.0)
Accepts `date_format` (one of MMDDYY, DDMMYY, MMDDYYYY, DDMMYYYY, YYMMDD, YYYYMMDD), `color`, and `font` parameters.
Formats the current date using the requested layout and sends it as a two-line message ("TODAY'S DATE" / formatted date string) to the sign.
Records the sent message in the `led_messages` database table.
Files: `webapp/routes_led.py`

Changed (4)

**LED control frontend buttons now fully functional** (v2.54.0)
Removed the "Time/date display feature coming soon" stub and disabled early-returns from `sendTimeDisplay()` and `sendDateDisplay()` in `templates/led_control.html`.
`sendDateDisplay()` corrected to call `/api/led/set_date_format` with the `date_format` key instead of the old copy-paste bug that called `/api/led/set_time_format` with `time_format`.
Files: `templates/led_control.html`

v2.53.2

Added (21)

**CTIA-required opt-out footer in all outgoing EAS alert SMS messages** (v2.53.2)
`app_core/notifications/sms.py` now appends `Reply STOP to stop msgs` to every alert message body, satisfying CTIA messaging guidelines that Twilio enforces during toll-free number verification. This footer is required for carrier delivery.
Test SMS messages also include `Reply STOP to stop msgs, HELP for help` so test submissions to Twilio reviewers demonstrate compliance.
Files: `app_core/notifications/sms.py`
**Expanded `/sms-compliance` opt-in disclosure page** (v2.53.2)
Added "Sample Message Format" section with an exact mock-up of what EAS alert messages look like (including the new STOP footer), satisfying Twilio's requirement to show a representative message sample on the opt-in page.
Added verbatim "Consent Disclosure Language" block (the exact text shown to recipients at opt-in) so Twilio reviewers can verify the opt-in flow.
Expanded opt-out keyword table to include all Twilio-standard keywords: STOP, STOP ALL, CANCEL, END, QUIT, UNSUBSCRIBE.
Removed Sprint (now T-Mobile) from the carrier list; list now reflects current major carriers.

**AMPR 44.0.0.0/8 Non-Commercial Network Disclaimer** (v2.53.1)
Added a prominent non-commercial network notice to `templates/about.html` and `templates/terms.html` for deployments accessible via the AMPRNet (44.0.0.0/8) address block.
Added the same notice as Section 13 to `docs/policies/TERMS_OF_USE.md`.
Explains FCC Part 97 non-commercial requirements, ARDC allocation policy, and that this service is operated strictly for non-commercial amateur radio research and emergency communications training.
Files: `templates/about.html`, `templates/terms.html`, `docs/policies/TERMS_OF_USE.md`
**Consistent visual theming across all pages** (v2.52.0)
Added the standard `admin-page-header` gradient banner to all 22 admin pages that previously lacked a consistent page header (application_settings, backups, county_boundaries, eas_decoder_monitor, mail_server, notifications, poller, zones, sessions, audio_archives, audio_sdr_fix, audio_sources, radio, radio_diagnostics, certbot, icecast, tailscale, tts, alert_feeds, environment, network, zigbee). Old ad-hoc h1/h2 heading rows removed.
Migrated `hardware_settings.html` from the non-admin `.page-header` to `.admin-page-header` for consistent admin section styling.
Fixed `index.html` (dashboard): removed the large inline `<style>` block that overrode the global `.page-header` CSS with conflicting padding, border-radius, and child element structure. Updated dashboard page-header HTML to use the canonical standard pattern (matching alerts.html, etc.).
Replaced hardcoded hex colors (`#6610f2`, `#6f42c1`) in `.admin-page-header.header-purple` in `static/css/admin.css` with theme-aware CSS variables (`var(--vibrant-indigo)`, `var(--secondary-color)`) so the purple header variant respects the active theme.

**Created missing `docs/javascripts/mermaid-init.js`** (v2.53.1)
`mkdocs.yml` referenced `javascripts/mermaid-init.js` as an extra JavaScript file, but the file and its parent directory did not exist, causing a 404 error when building the MkDocs documentation site.
Created `docs/javascripts/mermaid-init.js` with proper Mermaid initialization configuration (startOnLoad, theme variables, flowchart and ER diagram options).
Files: `docs/javascripts/mermaid-init.js`
**Fixed `.bg-light` text readability in dark and coffee themes** (v2.53.1)
The `.bg-light` CSS rule hard-coded `color: #212121` (near-black text), which became illegible when the `--light-color` variable resolves to a dark background colour (`#455169` in the dark theme, `#5b4333` in the coffee theme). Added theme-scoped overrides to use `var(--text-color)` and `var(--text-secondary)` for those two dark themes.
Files: `static/css/styles.css`
**Updated SMS Messaging Policy date** (v2.53.1)
Updated the "Last updated" field in `docs/policies/SMS_MESSAGING.md` from a placeholder to the current revision date.

Validates size hint from resource metadata before decoding
Estimates decoded size before base64 decode to prevent memory exhaustion
Uses strict base64 validation to catch malformed payloads
Verifies actual decoded size before writing to disk
File: `app_utils/ipaws_enrichment.py` - `save_ipaws_audio()` function

v2.43.4

2024-12-21

Fixed (38)

**CRITICAL: RBDS Buffer Management Fixed** - Changed from buffer-draining to index-based bit processing
Root cause: `_decode_rbds_groups()` was using `pop(0)` in a `while` loop, consuming ALL bits even during failed presync
When presync found valid blocks but spacing verification failed, bits were already consumed and lost
This caused constant `buffer=0` in logs and prevented synchronization from ever being achieved
Changed to index-based processing (like python-radio reference) that preserves unprocessed bits
Bits are only removed from buffer after successful processing or when buffer exceeds 6000 bit limit
Failed presync attempts now preserve bits for retry instead of discarding them
Added `_rbds_buffer_index` to track position in buffer without destroying data
Improved logging: spacing mismatches now show which block types caused the mismatch
Reference: https://github.com/ChrisDev8/python-radio/blob/main/decoder.py (lines 235-280)

**CRITICAL: SDR Audio Source Startup Failure** - Fixed `ModuleNotFoundError: No module named 'app_core.radio.rbds'`
Root cause: `FMDemodulator._init_rbds_state()` was trying to import `RBDSDecoder` from non-existent `.rbds` module
`RBDSDecoder` class is defined in the same file (`app_core/radio/demodulation.py` line 1662)
Removed incorrect import statement on line 297
SDR audio sources now start correctly without module import errors
Fixes "Audio source is error" message preventing audio monitoring
File: `app_core/radio/demodulation.py`

Changed (73)

**EAS Monitor Architecture** - Major architectural improvement: resample BEFORE queueing
Audio now resampled from source rate (48kHz) to 16kHz BEFORE entering EAS queue
EAS monitor receives pre-resampled 16kHz audio directly (no conversion needed)
Eliminates resampling bottleneck that caused packet drops
Reduces queue memory usage by 3x (16kHz vs 48kHz samples)
10000 chunk queue provides ~14 minutes of buffering (same duration at all rates due to resampling)
At 48kHz: 10000 chunks × 4096 samples = 40.96M samples / 48kHz = 853 seconds
At 16kHz: 10000 chunks × 1365 samples = 13.65M samples / 16kHz = 853 seconds
Removed ResamplingBroadcastAdapter dependency - no longer needed
Each audio source now has two queues: native rate for streaming, 16kHz for EAS

Fixed pre-existing sudoers syntax errors (escaped colons in chown commands)
Addresses: "The update script is asking for eas-stations password"
**Install/Update Scripts Webroot Directory Ownership** - Fixed webroot directory permissions in install.sh and update.sh
Changed ownership from www-data:www-data to root:root in both scripts
Ensures certbot (runs as root) can write challenge files during initial setup
Previously would fail on first webroot certificate attempt after fresh install

Eliminates confusion about where to configure serial-to-ethernet converter network settings
Users can now configure all LED sign settings (IP, port, serial mode, baud rate) in one location
**Admin Role Assignment Fix Script** - Added utility script to fix users without roles
Created `scripts/fix_admin_roles.py` to assign admin role to users created before roles were initialized
Script ensures roles/permissions are initialized and assigns admin role to any user without a role
Run with: `python3 scripts/fix_admin_roles.py`

v2.17.2

2025-12-09

Fixed (10)

**EAS Monitor Display Issues**: Fixed decoding rates showing >100% and display bouncing between states
Root cause 1: Rate calculation `samples_per_second` was sensitive to timing variations and could spike >100%
Root cause 2: During startup (first 2 seconds), rate calculation reported 0, triggering "no audio" warnings
Root cause 3: Frontend hysteresis (2 consecutive readings) wasn't enough to prevent flicker at 100ms WebSocket rate
Fix 1: Added exponential moving average (EMA) smoothing with alpha=0.3 to filter timing noise
Fix 2: Implemented 2-second minimum sample threshold - report expected rate during warmup instead of 0
Fix 3: Health percentage grows linearly 0-95% during warmup for smooth visual feedback
Fix 4: Increased frontend hysteresis from 2 to 5 consecutive readings (500ms stability required)
Fix 5: Properly clamp health_percentage to [0, 1] range in all code paths
Result: Rates never exceed 100%, smooth warmup transition, no state bouncing

Changed (6)

**Code Quality**: Extracted magic numbers to named class constants for easier configuration
`WARMUP_DURATION_SECONDS = 2` - Duration of warmup period
`WARMUP_MAX_HEALTH_PERCENTAGE = 0.95` - Maximum health shown during warmup
`RATE_SMOOTHING_ALPHA = 0.3` - EMA smoothing factor (lower=smoother, higher=more responsive)
`AUDIO_FLOWING_STABILITY_THRESHOLD = 5` - Frontend consecutive readings before state change
Improves maintainability and makes performance tuning easier

v2.17.1

2025-12-09

Fixed (14)

**CRITICAL: WebSocket Support Broken**: Fixed Flask-SocketIO async_mode mismatch that prevented WebSockets from working
Root cause: `app.py` used `async_mode='threading'` but gunicorn uses `--worker-class gevent`
This mismatch caused WebSockets to FAIL SILENTLY and fall back to long-polling
Fix: Changed `async_mode='threading'` to `async_mode='gevent'` to match gunicorn worker class
Impact: Enables real-time WebSocket updates at 10Hz (100ms) instead of 1-2 second polling intervals
This fixes why the entire site was polling despite WebSocket infrastructure being present
**UI White Space**: Fixed excessive white space at top of pages caused by `flex: 1` on `.page-shell`
Root cause: Flexbox layout with `flex: 1` caused content to expand and fill all vertical space
Fix: Removed `flex: 1` from `.page-shell` - footer's `margin-top: auto` handles sticky footer
Result: Pages now start content immediately after navbar without huge gaps
...4 more

Changed (8)

**WebSocket Infrastructure**: Audio monitoring page already uses WebSockets when available
VU meters, EAS monitor, and broadcast stats all receive real-time updates via WebSocket
System automatically falls back to polling only if WebSocket connection fails
With this fix, WebSockets should now work properly and polling fallback won't be needed
This fixes the root cause of why 10+ previous agent sessions couldn't solve the white space issue
The white space issue was subtle - `flex: 1` is a common flexbox pattern but caused unwanted expansion
The WebSocket issue explains why 32 setInterval() polling calls exist throughout the codebase
Future work: Extend WebSocket push service to broadcast all data types (alerts, system health, etc.) to eliminate remaining polling

v2.16.5

2025-12-09

Fixed (4)

**Application Startup Failure**: Fixed unterminated triple-quoted string literal in `webapp/admin/audio_ingest.py` at line 2237
Root cause: Docstring for legacy `generate_wav_stream()` function was never closed
This prevented database migrations from running and caused gunicorn workers to crash on startup
Fix: Properly closed the docstring and commented out the legacy code inside the function

v2.16.3

2025-12-09

Fixed (11)

**EAS Monitor Runtime Display**: Fixed runtime timer showing "0s" and buffer bar not filling on Audio Monitoring page
Root cause: API endpoint was not passing `wall_clock_runtime_seconds` from the audio-service metrics
Fix: Added `wall_clock_runtime_seconds` to the API response in `routes_eas_monitor_status.py`
**Audio Detail Page Error**: Fixed "Unable to load audio detail at this time" error when viewing IPAWS-generated alerts
Root cause: Template used `url_for('alert_detail', ...)` but the route is on the `api` blueprint
Fix: Changed to `url_for('api.alert_detail', ...)` in `audio_detail.html`
**Layout Spacing**: Reduced global `--layout-padding-top` from `1.5rem` to `0.5rem` to minimize gap between navbar and content
**Audit Logs UI**: Fixed stat-card styling conflict where global vibrant gradient styles were overriding the audit logs page local styles
Added more specific CSS selectors (`.stats-row .stat-card`) to ensure local styles take precedence
Used `!important` flags to override global pseudo-elements that added shimmer/glow effects
...1 more

v2.16.2

2025-12-09

Fixed (9)

`scripts/run_radio_manager.py`: Added proper exception logging during cleanup
`debug_airspy.py`: Changed bare `except:` to `except Exception:` with comments
**Defensive Coding**: Added None checks for `fetchone()` calls in migration and utility scripts:
`scripts/apply_source_type_migration.py`: Safe handling when column check returns no result
`app_core/migrations/versions/20251105_add_rbac_and_mfa.py`: Safe handling when INSERT RETURNING fails
`app_core/migrations/versions/20251116_populate_oled_example_screens.py`: Safe handling for screen insert
**Architecture Review**: Reviewed all 17 bugs from ARCHITECTURE_REVIEW_BUGS.md - most critical bugs (1-14) were already fixed in codebase
Remaining bugs are low-priority design issues or already addressed

v2.16.1

2025-12-09

Fixed (4)

**Dashboard Layout**: Removed duplicate `page-shell` class from dashboard container that caused large gap at top of page
Root cause: `page-shell` was applied to both `<main>` in base.html and inner container in index.html
This resulted in double top padding (from both elements)
Fix: Removed redundant `page-shell` class from inner `<div class="container-fluid">` in index.html

v2.16.0

2025-12-08

Changed (9)

**BREAKING: Service Renaming - Clean Architecture**
Renamed `audio_service.py` → `eas_monitoring_service.py` (reflects actual purpose)
Renamed `sdr_service.py` → `sdr_hardware_service.py` (clarifies exclusive hardware access)
**Why**: Old names were confusing and led to architectural mistakes
**No backward compatibility wrappers** - clean break for clarity
`eas_monitoring_service.py`: New name for EAS monitoring + audio processing service
`sdr_hardware_service.py`: New name for SDR hardware access service
`RENAME_SERVICES.md`: Updated to reflect completed rename
Old files (`audio_service.py`, `sdr_service.py`) removed completely

v2.15.5

2025-12-08

Fixed (12)

**CRITICAL: Complete SDR Hardware Separation**: Removed ALL SDR hardware access from audio-service.py
**Root Cause**: Both audio-service and sdr-service were fighting for USB access to SDR hardware
Removed `initialize_radio_receivers()` functionality from audio-service (kept stub for backward compat)
Removed RadioManager initialization and all `_radio_manager` references
Removed process_commands() SDR hardware operations (restart, get_spectrum, discover_devices)
Removed collect_metrics() radio_manager stats collection
Removed spectrum publishing loop with direct IQ sample access
**Result**: audio-service.py now ONLY subscribes to Redis channels from sdr-service
**Impact**: SDR hardware access is now exclusive to sdr-service.py container
**Why SDR Never Worked**: Both containers tried to open same USB devices → conflict
...2 more

v2.15.4

2025-12-08

Fixed (8)

**Code Quality: Removed Bare Except Statements**: Fixed 4 bare `except:` statements that could mask errors
`app_core/audio/eas_monitor.py`: Database rollback and SAME header parsing now log errors
`app_core/audio/streaming_same_decoder.py`: Message validation errors now logged at debug level
`app_core/audio/worker_coordinator_redis.py`: Redis connection close errors now logged
All exceptions now specify expected types (IndexError, AttributeError, Exception)
Improves debugging by making error paths visible in logs
Follows Python best practices for exception handling
**Impact**: Better error visibility and easier troubleshooting

v2.15.3

2025-12-08

Fixed (15)

**CRITICAL: Multi-Stream EAS Monitoring (LP1, LP2, SP1)**: Implemented per-source EAS monitoring
**Root Cause**: EAS monitor only listened to ONE audio source at a time (highest priority)
AudioIngestController.broadcast_pump selected only the highest priority running source
Main broadcast queue received audio from only ONE source, others were ignored
Result: LP1, LP2, SP1 web streams ran successfully but only ONE was monitored for EAS
**Fix**: Changed from single EAS monitor to per-source monitors (one for each stream)
Each audio source now has its own dedicated EAS monitor instance
All sources monitored simultaneously for SAME/EAS alerts
Alerts include source name in metadata for proper attribution
**Why IPAWS worked**: IPAWS uses internet polling (cap_poller.py), not audio monitoring
...5 more

v2.15.2

2025-12-08

Added (4)

**Diagnostic Tools**: Created comprehensive audio chain diagnostic utilities
`diagnose_audio_chain.py` - Full audio chain health check from SDR to EAS monitor
`fix_audio_source_sync.py` - Manual audio source sync tool with dry-run support
Both tools check receivers, audio sources, Redis connectivity, and IQ sample flow

Fixed (10)

**CRITICAL: Audio Chain for SDR Sources (LP1, LP2, SP1)**: Fixed missing audio pipeline for SDR-based EAS monitoring
Added automatic audio source synchronization on audio-service startup
Previously, audio sources for radio receivers weren't created automatically, breaking the audio chain
In separated architecture, sdr-service publishes IQ samples to Redis, but audio-service needs AudioSourceConfigDB entries
Without these entries, RedisSDRSourceAdapter instances weren't created, preventing audio from reaching EAS monitor
New `sync_radio_receiver_audio_sources()` function ensures audio sources exist for all enabled receivers
Sets critical `managed_by='radio'` flag to trigger Redis adapter creation
Enhanced logging shows receiver details, subscription channels, and startup status
Affects LP1, LP2, SP1 and any other SDR receivers with audio_output=True
**Impact**: Fixes complete loss of EAS monitoring from local/state primary SDR sources

v2.15.1

2025-12-08

Fixed (4)

Enhanced error handling and logging throughout WiFi operations
Frontend now properly parses backend network status response structure
Frontend disconnect sends empty body (backend auto-detects connection)
...6 more

v2.13.4

2025-12-07

Fixed (7)

**CRITICAL SEPARATION MISMATCH**: Fixed audio-service startup failing to load SDR sources from database
audio-service was trying to create SDRSourceAdapter for `source_type='sdr'` but had no radio manager (separated architecture)
Added detection: if source is radio-managed (`managed_by='radio'`), create RedisSDRSourceAdapter instead
Now audio-service properly loads SDR sources on startup and subscribes to IQ samples from sdr-service
✅ Audio sources persist across audio-service restarts
✅ No more "SDR source not available - radio manager missing" errors
✅ Separated architecture fully functional at startup

v2.13.3

2025-12-07

Fixed (7)

**CRITICAL AUDIO BUG**: Fixed source_type mismatch preventing audio from playing and Icecast mounts from appearing
`ensure_sdr_audio_monitor_source` was sending `source_type: 'sdr'` but audio-service expected `'redis_sdr'` for separated architecture
Result: RedisSDRSourceAdapter was never created, no audio demodulation happened, no Icecast mount appeared
Changed to `source_type: 'redis_sdr'` so audio-service properly creates Redis IQ subscriber and Icecast output
✅ Audio now plays from SDR receivers
✅ Icecast mounts now appear (e.g., /receiver.mp3)
✅ Complete end-to-end audio pipeline working

v2.13.2

2025-12-07

Fixed (9)

**Device Discovery**: Added `discover_devices` command handler in sdr-service
**Receiver Creation**: Added `reload_receivers` command to sync database changes to sdr-service
**Auto-Start**: New/updated receivers now automatically loaded by sdr-service
Webapp now properly communicates with sdr-service for device discovery and receiver management
_sync_radio_manager_state now tells sdr-service to reload configuration
Fallback to app-side radio manager if sdr-service unavailable
Better error handling and logging throughout signal chain
Device enumeration works in separated architecture

v2.13.1

2025-12-07

Fixed (9)

**CRITICAL AIRSPY BUG**: AirspyReceiver class was completely empty with NO Airspy-specific configuration
**Airspy Never Worked**: Device would never get warm because no samples were being processed correctly
Implemented proper `_open_handle()` override with Airspy R2 sample rate validation (2.5 MHz or 10 MHz only)
Configured linearity gain mode for optimal strong signal handling (FM/NOAA)
Added Bias-T safety (disabled by default to prevent equipment damage)
Airspy R2 TCXO provides accurate frequency - no PPM correction needed
Comprehensive Airspy R2 configuration logging
Sample rate validation with clear error messages

Added `frequency_correction_ppm` field to RadioReceiver model and database schema
Hardware frequency readback verification with mismatch warnings
Comprehensive frequency tuning diagnostics and logging

Fixed (6)

**Frequency Accuracy**: RTL-SDR and other low-cost SDRs now properly compensate for clock drift (typically ±50 PPM)
**Tuning Verification**: Actual tuned frequency is now logged and verified against requested frequency
**Diagnostic Logging**: Frequency settings, PPM correction, and readback values now logged for troubleshooting
Frequency accuracy can now be calibrated using PPM correction (e.g., calibrate with GSM cell tower or known station)
Mismatch warnings help identify hardware tuning issues (> 1 kHz error triggers warning)
Better separation: PPM correction in `ReceiverConfig` dataclass, not just database

v2.12.27

2025-12-07

Fixed (2)

**CRITICAL Demodulation Bug**: Added missing `process()` method to FMDemodulator and AMDemodulator classes that was being called by RedisSDRSourceAdapter but didn't exist, causing audio demodulation to fail completely
Fixed method signature mismatch where redis_sdr_adapter.py called `demodulator.process()` but only `demodulate()` existed, preventing any audio from being generated from IQ samples

v2.12.26

2025-12-07

Fixed (9)

**SDR Core**: Implemented missing `get_ring_buffer_stats()` method in `_SoapySDRReceiver` that was being called by sdr_service.py but didn't exist, causing silent failures in buffer health monitoring
**SDR Core**: Integrated SDRRingBuffer initialization in receiver startup to enable proper USB jitter absorption and backpressure handling
**SDR Core**: Ring buffer now properly instantiated when device opens, providing robust sample buffering for reliable 24/7 SDR operation
**SDR Core**: Capture loop now writes samples to ring buffer for overflow detection and backpressure monitoring
**SDR Core**: Ring buffer properly shut down when receiver stops, preventing resource leaks
Enhanced ring buffer statistics reporting with fallback to simple buffer stats when SDRRingBuffer unavailable
Added comprehensive buffer health metrics (overflow/underflow counts, fill percentage, total samples) to Redis
Improved separation between app.py and SDR service - all SDR operations completely independent of Flask application
Ring buffer overflow detection now logs dropped samples when processing can't keep up with USB data rate

v2.12.25

2025-12-05

Fixed (3)

**CRITICAL**: Fixed audio sources not starting when clicking start button - source name mismatch between webapp and audio-service (webapp sends "WIMT", audio-service expected "redis-WIMT")
Fixed race condition in metrics publishing where audio-service was deleting eas_monitor metrics from Redis causing "No metrics available from audio-service" error
Audio-service now uses original source names (not prefixed with "redis-") for separated architecture compatibility

v2.12.24

2025-12-05

Fixed (1)

Fixed audio-service container running Flask app.py during migrations by skipping database migrations in standalone service containers (audio-service, sdr-service, eas-service, hardware-service) that should not load the main Flask application

v2.12.23

2025-12-05

v2.12.22

2025-12-05

Fixed (2)

Fixed AirspyReceiver method override bug where `_open_device()` was defined but parent class uses `_open_handle()`, preventing Airspy-specific configuration (sample rate validation, linearity mode, bias-T settings) from ever executing
Added `get_ring_buffer_stats()` method to SDR receivers to fix method-not-found errors when SDR service attempts to publish ring buffer statistics to Redis

v2.12.21

v2.12.20

2025-11-27

Fixed (1)

Restored OLED alert scrolling by advancing the seamless scroll window based on elapsed frame time and speed settings so high-priority messages animate smoothly instead of freezing on a single frame.

v2.12.19

2025-11-26

Fixed (1)

Added IPv6 connectivity troubleshooting documentation (`docs/troubleshooting/FIX_IPV6_CONNECTIVITY.md`) so operators can diagnose SSL Labs IPv6 test failures and nginx upstream connection errors.

v2.12.18

2025-11-26

Fixed (1)

Redirected the policy docs URLs to the canonical `/terms` and `/privacy` routes and updated the documentation index to point to those pages so users no longer see divergent copies of the legal notices.

v2.12.17

2025-11-25

Fixed (1)

Redirect permission-denied responses to the dashboard blueprint's admin route so settings pages (including `/settings/alert-feeds`) return a proper 403 flow instead of a 500 BuildError when the non-namespaced endpoint is unavailable.

v2.12.15

2025-11-22

Changed (2)

Downsampled the continuous EAS monitor to 8 kHz (with automatic resampling from higher-rate sources) so SAME FSK decoding runs at an efficient rate without wasting CPU on unnecessary bandwidth.
Surfaced both the source and decoder sample rates in the monitor status API so operators can verify the tap is resampling correctly instead of assuming 22.05 kHz.

v2.12.14

2025-11-22

Fixed (2)

Matched the streaming decoder sample rate to the active ingest source so SAME correlation and preamble detection run at the correct frequency instead of drifting off-sync when sources run at 44.1 kHz.
Exposed the ingest-driven sample rate in the broadcast adapter stats returned with the EAS monitor status so operators can confirm the tap is aligned with the source.

v2.12.13

2025-12-05

Fixed (3)

Added broadcast subscription health (queue depth, underruns, last audio time) to the continuous monitor API so the dashboard shows when audio is actually flowing and operators can see the tap is healthy instead of guessing through empty fields.
Throttled repetitive buffer underrun warnings from the monitor's broadcast adapter while still counting them for visibility, preventing log spam when sources are temporarily quiet.
Exposed broadcast queue stats and the currently active source in `/api/audio/metrics` so VU meters can distinguish "no signal" from transport failures and display accurate runtime state.

v2.12.12

2025-12-05

Fixed (2)

Filled the continuous monitor status API with the streaming decoder's health, rate, and sync metrics so every dashboard field renders and operators can confirm the monitor is actively processing audio.
Tagged live audio metrics with each source's runtime status so the VU meters reflect whether inputs are running instead of dimming as if they were offline.

v2.12.10

2025-12-04

Changed (1)

Added a selectable streaming mode on the audio monitor that prefers the built-in HTTPS stream by default and only opts into Icecast when operators explicitly choose it, reducing stalls when external ports are blocked.

v2.12.2

2025-11-29

Fixed (2)

Added an automatic SoapySDR fallback that retries opening receivers without the serial filter when the initial connection fails, letting Airspy radios initialize even if the driver rejects the serialized arguments.
Updated the OLED layout migration to JSON-serialize `template_data` before persisting it to PostgreSQL so upgrades no longer crash with `can't adapt type 'dict'` errors.

v2.12.1

2025-11-27

Changed (2)

Rebuilt the EAS Station wordmark as an inline SVG partial that inherits theme colors for its accent bars and lettering, so the logo automatically matches whichever palette operators choose without filters or manual assets.
