<Summary type="rolling" window-days="90" release-count="10">
The SDKs expanded their data transport capabilities while tightening media handling. Data tracks shipped across livekit and livekit-ffi, enabling arbitrary data streaming alongside audio and video. In parallel, video buffering moved from unbounded queues to configurable bounded buffers defaulting to single-frame depth, eliminating lag during slow rendering or background wake-ups and keeping video synchronized with audio. The webrtc-sys layer upgraded to libwebrtc m144.
</Summary>

<Release version="livekit-ffi/v0.12.52" date="April 2, 2026" published="2026-04-02T04:41:34.000Z" url="https://github.com/livekit/rust-sdks/releases/tag/livekit-ffi/v0.12.52">
## Features

### Data tracks support

#905 by @ladvoc

## Fixes

### use the bounded buffer for video stream

#956 by @xianshijing-lk

Before this PR, it uses an unbounded buffer for video stream, that will cause multiple problems:
1, video will be lagged behind if rendering is slow or just wake up from background
2, it will be out of sync with audio

This PRs provides options to set a bounded buffer for video stream, and use 1 buffer as the default option.
</Release>
