### 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](https://developers.deepgram.com/changelog/self-hosted-changelog#deepgram-self-hosted-september-2025-release-250929) as soon as possible, where this behavior was resolved by a code change.**

* **Aura-2 Self-Hosted** — Now fully supports [Deepgram’s Aura-2 text-to-speech service](https://deepgram.com/learn/introducing-aura-2-enterprise-text-to-speech). You can refer to the [Deploy TTS Services](https://developers.deepgram.com/docs/deploy-tts-services) documentation for more details.
* **Automatic Engine Shutdown on GPU Errors** — Deepgram Engine will now automatically stop if a GPU error is detected, preventing potential data corruption. You can disable this by setting the environment variable `IMPELLER_DISABLE_AUTOSTOP=true`.
* **Smarter ZIP Code Formatting** — Now supports proper formatting for alphanumeric postal codes (e.g., UK, Canada).
* **General Improvements** — Keeps our software up-to-date.

**Reminder**: The Deepgram image repositories have been updated to reflect our "self-hosted" naming. Images should now be pulled from the `self-hosted-*` Quay repositories. Through August 2025, both `onprem-*` and `self-hosted-*` image repositories will receive identical image updates monthly, and we will announce image tags in the `self-hosted` repositories. **Starting in September 2025, we will only publish new images to `self-hosted-*` repos, deprecating `onprem-*` repository variants.**
