# Changelog
## 2026-04-10 - 1.17.0 - feat(proxy-engine)
upgrade the internal audio bus to 48kHz f32 with per-leg denoising and improve SIP leg routing
- switch mixer, prompt playback, and tool leg audio handling from 16kHz i16 to 48kHz f32 for higher-quality internal processing
- add f32 decode/encode and resampling support plus standalone RNNoise denoiser creation in codec-lib
- apply per-leg inbound noise suppression in the mixer before mix-minus generation
- fix passthrough call routing by matching the actual leg from the signaling source address when Call-IDs are shared
- correct dialed number extraction from bare SIP request URIs by parsing the user part directly
## 2026-04-10 - 1.16.0 - feat(proxy-engine)
integrate Kokoro TTS generation into proxy-engine and simplify TypeScript prompt handling to use cached WAV files
