  ## daily-js

  [View full release notes →](https://github.com/daily-co/daily-js/releases)

  ### 0.78.0

  * Fixed ejection logic to prevent incorrect ejections or joins when a user's local clock is out of sync. ⚠️ **Note:** Participants can no longer join if `eject_after_elapsed` is set to a negative value.
  * Fixed an `OverconstrainedError` on Chrome that occurred when providing an invalid audio `deviceId`.
  * Fixed an issue where unhandled errors during Krisp initialization could cause problems when joining a call.
  * Reverted a change that disabled background effects on Windows when software WebGL is in use. Instead, a `video-processor-warning` is now logged, as this scenario can significantly reduce video frame rates.
  * Improved `networkState` calculations by removing `recvPacketLoss`, which could be misleading.
  * Added `instanceId` to webhooks for raw tracks recordings.
  * Added performance logging for `enumerateDevices()` to help identify slow join times, especially on Firefox when the tab is not in focus.
  * Removed the beta feature warning from `testCallQuality()`.

  ## daily-python

  [View full release notes →](https://github.com/daily-co/daily-python/blob/main/CHANGELOG.md)

  ### 0.18.0

  * Introduced support for creating, updating, and removing custom audio tracks. You can now use `CallClient.add_custom_audio_track()`, `CallClient.update_custom_audio_track()`, and `CallClient.remove_custom_audio_track()` for advanced audio manipulation.
  * Improved `canReceive` permission support to ensure track states (`"off"`, `offReasons`) update correctly when permissions are granted or revoked.
  * Audio and video renderer callbacks (`set_audio_renderer()`, `set_video_renderer()`) now receive the audio or video source as the last argument.
  * Reduced "no subscription for consumer" and "Failed to close consumer" log messages from error to debug, as these often occur during normal participant disconnections.

  ## Media Services

  ### Recording

  * **Instance ID in Webhooks**: The `recording.ready-to-download` and `raw-tracks-recording-error` webhooks now include an `instance_id` to uniquely identify raw tracks recording sessions.
  * Fixed an issue to ensure the `instanceId` is correctly propagated for raw tracks recordings from the initial API call through to the final webhook event.

  ### Telephony

  * **`dialin.ready` Webhook**: Introduced the `dialin.ready` webhook event, which notifies you when a room's SIP endpoint is ready to receive an inbound call.

  * **`origin` Field in Dial-Out Webhooks**: Dial-out webhook events now include an `origin` field, specifying the PSTN number or SIP URI that initiated the call.

  * **Default SIP Codec**: Added a domain-level property to set default codecs for SIP/PSTN calls. Opus is now the default codec for all dial-in calls.

  * **On-Demand SIP Endpoints**: SIP endpoints for dial-out are now created on-demand when `startDialOut()` is called, improving resource efficiency and room creation reliability.

  * **Error Messaging**: Enhanced error messages for dial-in/out configurations during room creation.

  ## daily-js

  [View full release notes →](https://github.com/daily-co/daily-js/releases)

  ### 0.77.0

  #### Introduced `canReceive` Permission

  We extended the available permissions to include `canReceive`, which allows meeting owners to control the media tracks of others in the session. This feature enables use cases like "warm transfers" (e.g., ensuring a customer doesn't hear an agent before the handoff is complete) and other scenarios requiring selective visibility or audibility within a call. See the [participant permissions documentation](/reference/daily-js/instance-methods/participants#param-permissions) for details.

  #### Improved Network Quality Statistics

  We introduced two new fields in the object returned by [`getNetworkStats()`](/reference/daily-js/instance-methods/get-network-stats) to provide more accurate network quality data: `networkState` and `networkStateReasons`. These replace the deprecated `threshold` and `quality` fields, offering a more reliable assessment based on send/receive packet loss, round-trip time, and available outgoing bitrate.

  #### Bug fixes and improvements

  * Fixed `proxyUrl` support in `dailyConfig`.
  * Optimized background effects on Windows by disabling them when hardware acceleration is unavailable.
  * Updated internal dependencies to resolve security vulnerabilities.
  * Simplified `recordings_bucket` response in `room()` method for enhanced security.

  ### 0.76.0

  #### Bug fixes and performance improvements

  * Updated Krisp noise cancellation library to v2.2.1.
  * Fixed switching back from custom video track to device track via `setInputDevicesAsync()`.

  * Added `enable_dialout` to TypeScript definitions for `DailyRoomInfo`.

  ### 0.75.2

  #### Bug fixes

  * Fixed unnecessary video track re-acquisition during input settings updates.

  ### 0.75.1

  #### Bug fixes

  * Fixed video constraint preservation when changing devices.
  * Removed console error for null `deviceId` in `setInputDevicesAsync`.

  ### 0.75.0

  #### Enhanced Participant Type for Dial-in/out

  The `participant` object now includes specific `participantType` values to identify telephony participants: `sip-dial-in`, `sip-dial-out`, `pstn-dial-in`, and `pstn-dial-out`. This allows for clearer identification of how participants joined via SIP or PSTN dial-in/out.

  #### Dynamic Input Track Constraints

  Introduced support for dynamically customizing media track constraints during a call using [`updateInputSettings()`](/reference/daily-js/instance-methods/update-input-settings). This allows changing camera resolution, frame rate, or switching between front and rear cameras without rejoining. The previous constraint-setting methods (`userMediaAudioConstraints`, `userMediaVideoConstraints`, and `setBandwidth` trackConstraints) are now deprecated.

  #### Bug fixes and improvements

  * Fixed track event reliability for rapid muting/unmuting and custom tracks.
  * Fixed track event participant info on leave.
  * Improved Krisp initialization error handling.
  * Fixed `ondevicechange` undefined error on certain systems.
  * Updated Banuba SDK to eliminate need for `'unsafe-eval'` CSP directive with `avoidEval: true`.
  * Updated minimum supported version to 0.64.0.

  * Added `enable_dialout` to TypeScript definitions.

  ### 0.72.1

  #### Reverted Erroneous API Changes

  Reverted unintended deprecation notices for `updateInputSettings()` and dynamic track constraints to maintain React Native's existing device handling APIs.

  ### 0.72.0

  #### Enhanced Participant Type for Dial-in/out

  Added specific `participantType` values for telephony participants: `sip-dial-in`, `sip-dial-out`, `pstn-dial-in`, and `pstn-dial-out`.

  #### Added Audio-Only Raw Tracks Recording

  Added `raw-tracks-audio-only` streaming config for audio-only recording support.

  #### Bug fixes

  * Fixed track event reliability for muting and custom tracks.
  * Updated internal REST APIs to use native utilities.
  * Added participant info to `track-stopped` events on leave.

  ***

  ## daily-js

  ### 0.74.0

  #### Updated Krisp CSP Requirements

  Added missing `blob:` source to the [CSP guide](/docs/guides/privacy-and-security/content-security-policy):

  ```js theme={null}
  script-src 'self' https://unpkg.com/@daily-co/daily-js blob:;
  ```

  #### Follow-up fix for Safari Audio Processing Detection

  Fixed a logical error in Safari version comparison for audio processing support. We resolved an edge case where Safari versions above 18 were incorrectly flagged as unsupported. This completes the [Safari 17.4+ audio processing detection fix](/changelog/2024#fixed-audio-processing-detection-in-safari-17-0-17-3) from our previous release.

  This change ensures accurate audio processing support detection across all Safari versions.

  #### Fixed Call Quality Test Error Handling

  Fixed error handling in `testCallQuality()` when rate limits are hit and improved promise rejection handling to avoid uncaught errors. Test failures now properly resolve with a FAILED result instead of throwing.

  #### Added Session ID to Dial-in Events

  Added sessionId field to all dial-in events: `dialin-connected`, `dialin-error`, `dialin-stopped`, and `dialin-warning`.

  For example:

  ```js theme={null}
  dialinConnected: { sessionId: 'abc-123', sipFrom: '+1234567890', ... }
  ```

  #### Version Support Update

  * The oldest supported version of `daily-js` is now 0.63.0.

  ***

  ## react-native-daily-js

  ### 0.71.0

  This release also includes several core improvements shared with daily-js 0.74.0:

  * Added sessionId to dial-in events

  See the daily-js 0.74.0 section for full details on these changes.

  ***

  ## daily-android

  ### 0.28.0

  #### Added support for Cloudflare TURN/STUN servers

  Added support for using Cloudflare TURN/STUN servers for ICE connections. If you're interested in using this for your Daily domain, please contact [help@daily.co](mailto:help@daily.co)

  #### Fixed Android Proguard Build Configuration

  Fixed an issue where apps using R8/Proguard would fail to build due to missing Banuba video processor classes:

  * Added proper Proguard configuration for optional Banuba SDK dependencies
  * Ensured R8 optimization doesn't fail on missing video processor classes
  * Maintained backwards compatibility with existing video processor integrations

  This change prevents build failures in release builds when the video processor plugin is not included.

  ### 0.27.0

  #### Fixed crash when creating and deleting `VideoTextureView`/`VideoTrackCapturerToSurface` without also creating a `CallClient`.

  Fixed an issue where `daily-android` would crash when cleaning up video views without an active CallClient:

  * Moved native library initialization to shared context to prevent premature loading
  * Added safety checks to prevent cleanup of uninitialized native contexts
  * Improved synchronization of client tracking in shared context

  This change prevents crashes when creating and destroying video views without an active call client, improving stability for applications that conditionally initialize video components.

  #### Enhanced Call Reliability during Meeting Moves

  Improved call reliability during meeting moves by implementing increased retry attempts for meeting moves to handle longer backend processing times.

  // Start a cloud recording
  await call.startRecording({
    instanceId: '123e4567-e89b-12d3-a456-426614174000',
    type: 'cloud',
    layout: {
      preset: 'default',
    },
  });

  // Start raw-tracks recording in parallel
  await call.startRecording({
    instanceId: '987fdef0-c65b-11d1-b2e2-526614174000',
    type: 'raw-tracks',
  });
  ```

  * New `type` parameter in `startRecording()` ([docs](/reference/daily-js/instance-methods/start-recording)) API accepts `'cloud'`, `'raw-tracks'`, or `'local'`
  * Recording types must be enabled via `enable_recording` property on room/domain
  * Each recording instance requires a unique UUID via `instanceId` parameter

  You can now run cloud recordings and raw track captures simultaneously, enabling both processed and unprocessed recording workflows from a single call.

  #### Added Audio-Only Support for Raw Tracks Recording

  Added support for audio-only recording in raw-tracks recordings:

  ```typescript theme={null}
  // Start a raw-tracks recording with audio only
  await call.startRecording({
    instanceId: '123e4567-e89b-12d3-a456-426614174000',
    type: 'raw-tracks',
    layout: {
      preset: 'raw-tracks-audio-only',
    },
  });
  ```

  * New `raw-tracks-audio-only` preset captures only audio tracks, reducing storage requirements and simplifying post-processing workflows
  * Preset must be specified at recording start - cannot be changed via `updateRecording()`
  * Compatible with existing `raw-tracks` processing tools for audio extraction and analysis

  This addition makes raw-tracks recordings more flexible for audio-focused use cases where individual tracks are needed for post-processing like podcasting, voice analysis, and audio archival.

  #### Added Raw Tracks Processing Tools

  Released an open-source suite of tools for processing raw-tracks recordings:

  * New [`raw-tracks-tools` CLI](https://github.com/daily-co/raw-tracks-tools) provides tools for analyzing, converting and compositing WebM files from raw-tracks recordings
  * Supports track alignment, synchronization, and layout composition using Daily's VCS engine
  * Complements existing GUI tools like CloudConvert and Handbrake with more precise control over WebM processing

  This release makes raw-tracks recordings more accessible for post-processing workflows, especially for high-quality audio/video production.

  #### Added Audio Recording Loss Detection

  Added automatic detection of audio quality issues in recordings and streams. This fixes issues where audio quality issues where audio or video tracks were visible during the live call but not in the final recording/stream.

  #### Improved Recording Reliability with Network Optimizations

  Enhanced network reliability for all recording types (cloud, raw-tracks, live streaming) and phone integration:

  * Increased UDP buffer sizes to prevent packet loss between servers
  * Added server-to-server retransmission between SFU and media workers
  * Reduces recording freezes and dropped tracks in environments with network congestion

  #### Fixed Missing Tracks in Recordings

  Fixed an issue where tracks could be missing from recordings when added during WebSocket reconnections between SFU and recording services. New tracks are now properly subscribed even during connection re-establishment.

  ### Telephony

  #### Renamed Dialout Timeout Configuration Field

  Renamed dialout configuration parameter from `max_alone_duration_sec` to `max_idle_timeout_sec` to better describe its purpose of controlling how long dialout participants remain in an idle room.

  #### Added Participant Type Support in participants() for Phone Participants

  Added distinct participant types for phone participants in [participants()](/reference/daily-js/instance-methods/participants) to enable better handling of SIP and PSTN users:

  * New participant types: `sip-dial-in`, `sip-dial-out`, `pstn-dial-in`, `pstn-dial-out`
  * Automatically set for all phone-based participants, including umbrella participants

  This helps developers better identify and manage phone participants in their applications.

  #### Fixed Dialout ICE Connection Reliability

  Fixed an issue where SIP dialout calls could hang during ICE connection negotiation, improving the reliability of phone system integration.

  #### Added `dialout_config` to Room Configuration

  Added `dialout_config` ([docs](/reference/rest-api/rooms/get-room#response-config-dialout-config)) as a room-level configuration option to control dialout behavior:

  * `dialout_config.allow_room_start`: Allow dialouts to start an empty room
  * `dialout_config.max_idle_timeout_sec`: Control how long a dialout participant can remain in a room alone
  * `dialout_config.dialout_geo`: Specify region for dialout sessions

  ### Transcription

  #### Unified Transcription Configuration Across Live and Batch Processing

  Aligned transcription configuration options between live transcription and batch processing for consistent API usage:

  ```js theme={null}
  // Live transcription
  await call.startTranscription({
    language: 'fr-CA',
    model: 'nova-2-general',
  });
  ```

  * All configuration options from [live transcription](/reference/daily-js/instance-methods/start-transcription) (language, model, punctuate, etc.) now supported in [batch processing](/reference/rest-api/batch-processor/reference/submit-job)
  * Previous undocumented `params` field maintained for backward compatibility
  * Added new `extra` field for additional Deepgram parameters in both APIs

  Simplifies transcription configuration by providing a consistent interface across real-time and batch processing workflows.

  #### Added Room Name in Transcription API

  Enhanced transcription list and info endpoints with room name support:

  ```js theme={null}
  // List transcripts with room name filter
  GET /api/transcripts?room_name=my-room*

  // Transcript info now includes room name
  {
   "transcriptId": "123",
   "roomId": "456",
   "roomName": "my-room",
   // ...other fields
  }
  ```

  ### Webhooks

  #### New transcription webhook events

  Added three new webhook events to track the full lifecycle of transcriptions:

  * [`transcript.started`](/reference/rest-api/webhooks/events/transcript-started) indicates transcription has begun, including metadata like room ID, instance ID and initial status
  * [`transcript.ready-to-download`](/reference/rest-api/webhooks/events/transcript-ready-to-download) fires when transcription completes, providing S3 location details for downloading the transcript
  * [`transcript.error`](/reference/rest-api/webhooks/events/transcript-error) provides detailed error information and context if transcription fails during any stage

  Monitor and automate transcription workflows with comprehensive status updates and error handling through webhooks.
