### This Release Contains The Following Changes

- **Expands Nova-3 Monolingual Language Support** — Nova-3 now supports 21 additional languages, bringing stronger accuracy and contextual understanding across:

  - **Eastern Europe and Eurasia**: Bulgarian (bg), Czech (cs), Greek (el), Hungarian (hu), Polish (pl), Romanian (ro), Russian (ru), Slovak (sk), Ukrainian (uk)
  - **Nordics and Baltics**: Estonian (et), Finnish (fi), Latvian (lv), Lithuanian (lt)
  - **Western Europe**: Catalan (ca), Flemish (nl-BE), Swiss German (de-CH)
  - **South Asia**: Hindi (hi)
  - **East Asia**: Japanese (ja), Korean (ko, ko-KR)
  - **Southeast Asia**: Malay (ms), Vietnamese (vi)

  **Note**: This release originally introduced 11 new languages (Bulgarian, Czech, Finnish, Hindi, Hungarian, Japanese, Korean, Polish, Russian, Ukrainian, and Vietnamese). The 10 additional languages from the 251210 release (Greek, Romanian, Slovak, Catalan, Lithuanian, Latvian, Estonian, Flemish, Swiss German, and Malay) are also supported via backward compatibility.

  Learn more in our announcement blogs: [11 new languages](https://deepgram.com/learn/deepgram-expands-nova-3-with-11-new-languages-across-europe-and-asia) and [10 additional languages](https://deepgram.com/learn/deepgram-expands-nova-3-with-10-new-languages-and-multilingual-keyterm-prompting).

- **Adds 36-Language Detection Model** — Adds support for a new language detection model that handles 36 languages. This feature requires enabling the `use_v2_language_detection` feature flag in the Engine TOML configuration. Language detection is available for pre-recorded audio only. Learn more in the [language detection documentation](/guides/models-and-languages-language-detection).

- **Updates Status Endpoint** — Updates the `/v1/status` endpoint to better reflect node startup and runtime state, preventing false Critical reports when the API starts before an Engine driver is ready. See the [status endpoint documentation](/guides/deployment-self-hosted-status-endpoint) for the new status flow:
  - **Initializing** — Reported during node startup; transitions to Ready once initialization completes.
  - **Ready** — The node can service requests; transitions to Healthy after enough successful requests, or Critical if errors occur.
  - **Healthy** — Sustained success; can transition to Critical if failures arise.
  - **Critical** — Indicates node failures; can recover back to Ready once node can service requests again.

- **Enhances API Graceful Shutdown** — Resolves an issue where the API container would not properly wait for outstanding work to complete before shutting down. The graceful shutdown period now defaults to approximately 10 minutes.

- **Improves Address Formatting** — Improves formatting for street numbers in addresses.

- **Improves Aura-2 Latency Consistency** — Improves latency consistency for Aura-2 text-to-speech requests.

- **Deprecates Legacy Intelligence Features** — Legacy Intelligence features (`analyze_sentiment=true`, `detect_topics=true`, `summarize=v1`, and `summarize=true` v1 structure) are now deprecated in favor of newer versions. Requests using these parameters will return HTTP 400 errors. Migration guidance:

  - `analyze_sentiment=true` → use `sentiment=true`
  - `detect_topics=true` → use `topics=true`
  - `summarize=v1` → use `summarize=true` or `summarize=v2`

  See the [Speech-to-Text changelog](/guides/self-hosted-deployments-changelog#legacy-intelligence-features-deprecated) for more details.

- **Adds Streaming Entity Detection** — Adds support for streaming [entity detection](/guides/self-hosted-deployments-6-detect-entities). See the product changelog entry for full details: [Entity Detection Now Available for Streaming Speech-to-Text](/guides/self-hosted-deployments-changelog#entity-detection-now-available-for-streaming-speech-to-text).

- **Includes General Improvements** — Keeps our software up-to-date.
