# SDK releases: JavaScript SDK v2.70.0 - Added batch and realtime Speech to Text transcript editing… By Steven Van · 2026-09-28 The JavaScript and Python SDKs both reach v2.70.0 with transcript editing types, and the CLI fixes an API key and OAuth credential conflict. ElevenLabs released version 2.70.0 of its JavaScript and Python SDKs, along with version 1.4.0 of its CLI, in its [September 28 changelog](). The SDK updates track new [ElevenLabs]() API features. - **JavaScript and Python SDK v2.70.0:** Both add types for batch and realtime Speech to Text transcript editing, branch filtering and cost fields for test invocation summaries, knowledge base auto-discovery, the Text to Dialogue Professional Voice Clone option (usePvcAsIvc in JavaScript, use\_pvc\_as\_ivc in Python) and the deepseek-v41-flash agent model. The filter is branchId in JavaScript and branch\_id in Python. - **CLI v1.4.0:** Requests made with an explicit API key no longer also send stored OAuth credentials, which had caused authentication failures. The release also adds descriptions for the feedback command group and instructions for reporting missing capabilities to generated agent skills. The API client was regenerated with Flows template endpoints and current schema types. The transcript editing types match the API change in the same changelog. Batch and realtime transcription now accept a natural-language edit instruction of up to 2,000 characters.
