1.1.0

September 8, 2025

What’s New

  • The connector now supports the Custom headers field for all operations. Custom headers always take precedence over any existing headers passed as part of an implementation, overwriting values where the same key is used.

  • The Nvidia connection type now includes the custom [Nvidia] Base URL field for sending inference requests, with https://integrate.api.nvidia.com as the default. This supports custom and self-hosted URLs.

  • The Messages field in the [Chat] Completions operation now supports DataSense, which provides schema support.

  • The Tools field in the [Tools] Native Template (Reasoning only) operation now supports DataSense, which provides schema support.

  • The [Agent] Define Prompt Template, [Chat] Answer Prompt, [Chat] Completions, and [Tools] Native Template (Reasoning only) operations now provide default support for toxicity detection by returning the new contentFilterResults and promptFilterResults additional attributes in the response.

  • The connector now supports the Gemini connection type (beta) in Text Generation Config and Vision Config.

  • In the Azure OpenAI connection type:

    • The new [Azure OpenAI] API Version and [Azure OpenAI] Endpoint fields are added to the General tab.

    • In the General tab, there is a new section called Required: Enter URL or Parameters which has the [Azure OpenAI] Endpoint, [Azure OpenAI] Resource Name, and [Azure OpenAI] Deployment ID fields. In this section, you can either provide the default or a custom endpoint URL (which is used directly and overrides any parameter values), or provide the resource name and deployment ID (which are used to construct the base URL).

    • The [Azure OpenAI] User field is moved from the General tab to the Advanced tab.
