## 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.

For release details, see [deepgram-python-sdk v7.9.0](https://github.com/deepgram/deepgram-python-sdk/releases/tag/v7.9.0).

### JavaScript SDK v5.11.0

Deepgram JavaScript SDK `v5.11.0` adds `socket.sendForceEndTurn()` and Agent
Flux TTS `expressivity` from `-2` through `2`. The former `SpeakV2Speed`
constants and `Aura2PerseoIt` model constants remain as deprecated aliases for
source compatibility.

For release details, see [deepgram-js-sdk v5.11.0](https://github.com/deepgram/deepgram-js-sdk/releases/tag/v5.11.0).

### Java SDK v0.10.0

Deepgram Java SDK `v0.10.0` adds `sendForceEndTurn(...)`, Agent Flux TTS
`expressivity`, and the expanded Flux TTS speed range.

This pre-1.0 release includes breaking changes: it removes `SpeakV2Speed` and
its named speed constants, plus the unsupported `AURA2PERSEO_IT` model
constants and visitor methods. Configure speed directly with a numeric value,
such as `.speed(1.05)`, and use a supported Speak V1 model.

For release details, see [deepgram-java-sdk v0.10.0](https://github.com/deepgram/deepgram-java-sdk/releases/tag/v0.10.0). For migration steps, see the [v0.9 to v0.10 migration guide](https://github.com/deepgram/deepgram-java-sdk/blob/main/docs/Migrating-v0.9-to-v0.10.md).
