### This Release Contains The Following Changes

- Adds support for our new class of [English Nova-3](https://deepgram.com/learn/introducing-nova-3-speech-to-text-api) models, including both General and [Medical](https://deepgram.com/learn/introducing-nova-3-medical-speech-to-text-api). Use `model=nova-3` or `model=nova-3-medical`. For further information, see our [Model Selection](https://developers.deepgram.com/docs/maintaining#model-selection) documentation. Contact your Deepgram account representative for access to Nova-3. Please note that multilingual Nova-3 will be available in a later release.
- Significantly improves formatting for all English transcripts. This new formatting is powered by a dedicated Named Entity Recognition (NER) model that performs sophisticated recognition of entities, including phone numbers, addresses, and dates, in order to return excellent formatted transcripts. NER is required for smart-formatted Nova-3 transcripts, and strongly suggested for all other speech-to-text transcripts.
  - Consult our [instructions for enabling NER formatting](https://deepgram.gitbook.io/help-center/self-hosted/how-can-i-enable-ner-formatting-in-my-self-hosted-deployment) to make required updates to configuration as well as models.
  - Improvements to smart-formatting have modified the formatting of some entity classes. Please contact your Deepgram account representative if you have any questions.


- Introduces self-hosted support for our [Voice Agent](https://deepgram.com/product/voice-agent-api) API. Contact your Deepgram account representative to get started with it.
- Adds support for numeral formatting in [10 new languages](https://developers.deepgram.com/docs/numerals). Use `numerals=true`.
- 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. For the next six months, both `onprem-*` and `self-hosted-*` image repositories will receive identical image updates monthly, and we will announce image tags in the `self-hosted` repositories. Subsequently, we will only publish new images to `self-hosted-*` repos, deprecating `onprem-*` repository variants.
- Keeps our software up-to-date.
