 All notable changes to iNTERCEPT will be documented in this file.
 
+## [2.15.0] - 2026-02-09
+
+### Added
+- **Real-time WebSocket Waterfall** - I/Q capture with server-side FFT
+  - Click-to-tune, zoom controls, and auto-scaling quantization
+  - Shared waterfall UI across SDR modes with function bar controls
+  - WebSocket frame serialization and connection reuse
+- **Cross-Module Frequency Routing** - Tune from Listening Post directly to decoders
+- **Pure Python SSTV Decoder** - Replaces broken slowrx C dependency
+  - Real-time decode progress with partial image streaming
+  - VIS detector state in signal monitor diagnostics
+  - Image gallery with delete and download functionality
+- **Real-time Signal Scope** - Live signal visualization for pager, sensor, and SSTV modes
+- **SSTV Image Gallery** - Delete and download decoded images
+- **USB Device Probe** - Detect broken SDR devices before rtl_fm crashes
+
+### Fixed
+- DMR dsd-fme protocol flags, device label, and tuning controls
+- DMR frontend/backend state desync causing 409 on start
+- Digital voice decoder producing no output due to wrong dsd-fme flags
+- SDR device lock-up from unreleased device registry on process crash
+- APRS crash on large station count and station list overflow
+- Settings modal overflowing viewport on smaller screens
+- Waterfall crash on zoom by reusing WebSocket and adding USB release retry
+- PD120 SSTV decode hang and false leader tone detection
+- WebSocket waterfall blocked by login redirect
+- TSCM sweep KeyError on RiskLevel.NEEDS_REVIEW
+
+### Removed
+- GSM Spy functionality removed for legal compliance
