title: Media agent for THEOplayer v1.0.0
source: https://docs.newrelic.com/docs/release-notes/streaming-browser-release-notes/streaming-browser-agent-theo-26-10-26
---

### New features

-   **THEOplayer Web SDK support:** Initial stable release of the New Relic THEOplayer tracker for browser environments. Import via `@newrelic/video-theo/browser`.
-   **Browser entry point:** Dedicated `@newrelic/video-theo/browser` subpath that excludes the Vega/connected-device pipeline for browser-only bundles.
-   **Bitrate tracking:** Reports `contentBitrate`, `contentManifestBitrate`, `contentSegmentDownloadBitrate`, and `contentNetworkDownloadBitrate`.
-   **Rendition quality tracking:** Tracks active rendition height, width, and bandwidth via track-level quality change events.
-   **Multi-format support:** HLS and DASH streams supported through THEOplayer's native adaptive streaming.

### Improvements

-   **`@newrelic/video-core` updated to 5.1.0**, enabling QoE drain callbacks on `sendStart`/`sendEnd` via `getHarvester()`.
-   **Player name:** `playerName` attribute reports as `THEOplayer`.
-   **Error code handling:** `errorCode` is omitted from events when no SDK-provided code is available, avoiding meaningless sentinel values in NRDB.
