  Krisp publishes release notes per SDK build rather than one dated platform changelog. The index does not
  expose publication dates, so no date field is recorded here. This is the recent window surfaced by the
  docs index and /llms.txt as of the capture date, not full history.
entries:
- product: RTC JS Browser SDK
  version: 2.3.9
  url: https://sdk-docs.krisp.ai/changelog/rtc-js-sdk-239.md
  breaking: false
  highlights:
  - Improved SharedArrayBuffer fallback — the SDK now detects when SharedArrayBuffer is unavailable and
    automatically falls back to postMessage transport instead of breaking audio processing.
  - Fixed dead mic issue — when Noise Cancellation is enabled mid-call, raw audio is passed through until
    processed audio is ready, preventing the microphone from being muted during filter warm-up. Accent
    Conversion outputs silence during warm-up by design.
  - Fixed a Chrome AudioWorklet race condition — filter creation now retries until the AudioWorklet is
    registered.
  - WASM model and session initialization failures now trigger the filter's error event instead of
    incorrectly reporting the filter as ready; a related memory leak was fixed.
- product: VIVA Python SDK
  version: 1.11.0
  url: https://sdk-docs.krisp.ai/changelog/viva-python-sdk-v1110.md
  breaking: true
  breaking_note: The previous Interrupt Prediction model file is not compatible with the new SDK.
  additions:
  - Introduced stats API.
  highlights:
  - Reduced CPU consumption for Voice Isolation models by 30–40% on armv8a hardware using FP16 SIMD
    instructions where available.
  - Updated the Interrupt Prediction model file krisp-viva-ip-v1.1 with updated model encryption; no
    output quality change.
