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 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. You can refer to the 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.
