### This Release Contains The Following Changes

⚠️ **Please be advised that this release is known to contain an Aura-2 TTS defect where the wrong conditioning priors are applied, resulting in the insertion of a random utterance. While the issue is rare, we strongly advise all Aura-2 TTS customers to update to [release-250929](/guides/self-hosted-deployments-changelog#deepgram-self-hosted-september-2025-release-250929) as soon as possible, where this behavior was resolved by a code change.**

- GA support for Nova-3 monolingual [German, Dutch, Swedish, Danish](https://deepgram.com/learn/deepgram-expands-nova-3-with-german-dutch-swedish-and-danish-support), [Spanish, French, and Portuguese](https://deepgram.com/learn/deepgram-expands-nova-3-with-spanish-french-and-portuguese-support) languages. Ask your Deepgram account representative for the new models.
- Improves [Utterance End](/guides/streaming-audio-utterance-end) settings to allow lower minimum `utterance_end_ms` values, aligning with configured step size for self-hosted deployments.
- **General Improvements** — Keeps our software up-to-date.

**Important**: The `onprem-*` image tags are now deprecated and are no longer supported or updated. As announced in our [previous release](/guides/more-changelog-2025-8-28), we have transitioned to using only `self-hosted-*` repositories. Please update your deployments to use the `self-hosted-*` image tags listed above.
