SDK releases

Deepgram Python SDK v7.9.0, JavaScript SDK v5.11.0, and Java SDK v0.10.0 are now available. All three releases add Voice Agent ForceEndTurn support, Flux TTS expressivity controls for Agent providers, and the expanded Flux TTS speed range of 0.5 through 1.5 in 0.05 increments.

Python SDK v7.9.0

Deepgram Python SDK v7.9.0 adds send_force_end_turn() and typed ForceEndTurn messages for Voice Agent sessions using a Deepgram V2 (Flux STT) listen provider. It also adds integer Agent Flux TTS expressivity from -2 through 2 and the expanded Flux TTS speed range. The unsupported aura-2-perseo-it model is removed from Speak V1 model literals; the API never served that model.
