By Steven Van · 2026-10-19

The @elevenlabs/client 1.28.0 release adds an experimental persistentSession option and an onConversationHistory callback for resuming WebSocket text chats.

The [ElevenLabs](<https://creatorstoolbox.com/tools/elevenlabs>) client library, @elevenlabs/client, has a [1.28.0 release](<https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs%2Fclient%401.28.0>) that adds resumable text conversations over WebSocket.

## Persistent sessions

The release adds an experimental persistentSession session option. It is meant for text conversations over WebSocket that can be resumed.

## Conversation history and metadata

A new onConversationHistory callback receives the transcript rows the server replays when a session resumes. WebSocket sessions now also emit onConversationMetadata.

## Dependencies

The patch changes update @elevenlabs/types to 0.25.0.
