Key feature work delivered includes ROCm driver version updates (6.4.0 and 6.4.1) to improve AMD hardware compatibility and performance, as evidenced by commits Update ROCm to 6.4.0 (#18264) and Update ROCm to 6.4.1 (#18364). The team implemented dynamic configuration and camera masking to support runtime policy updates without restarts (Dynamic Config Updates (#18353) and Dynamically update masks and zones for cameras (#18359)). Initial custom classification model config support was added to enable user-supplied models (Initial custom classification model config support (#18362)), along with a Min face configuration option to fine-tune detection sensitivity (Min face configuration option (#18284)). Telemetry opt-out was introduced to respect privacy and data preferences (Opt out of OpenVINO telemetry (#18015)). Additional enhancements included miscellaneous tweaks, documentation tooling updates, and the ability to configure when custom classification models run, plus a basic startup config editor to ease recovery (Configure When Custom Classification Models Run (#18380) and Add basic config editor when Frigate can't startup (#18383)). Tiered recordings were introduced to support different recording strategies (Tiered Recordings (#18492)). Major bug fixes addressed loitering behavior clarity, ONNX runtime issues on Jetson, bird classification guard rails, LPR correctness, and broader build/compatibility improvements (Clarify loitering behavior (#17984); Fix Jetson ONNXRuntime (#18370); Don’t Run Bird Classification If Model Not Downloaded Yet (#18474); Fix Incorrectly Running LPR (#18390); General Fixes (#18379); Build System Cleanup (#18372); Intel updates (#18493)).
