### 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.**

- **GPU Required Configuration** — New `[health]` section in engine.toml with `gpu_required` configuration option allows Engine to fail on startup if no GPU is detected. While Engine can run without a GPU, production deployments require one for acceptable performance. Set `gpu_required = true` to fail fast if no GPU is available, rather than running with severely degraded performance. Default: false.
- **General Improvements** — Keeps our software up-to-date.

**Important**: This is the last release that will include `onprem-*` image tags. The Deepgram image repositories have been updated to reflect our "self-hosted" naming. Images should now be pulled from the `self-hosted-*` Quay repositories. **Starting with the next release in September 2025, we will only publish new images to `self-hosted-*` repos, deprecating `onprem-*` repository variants.**
