10.5.1

Version 10.5.1 of the Microsoft.Extensions.AI packages stabilizes CodeInterpreter, WebSearch, and ImageGeneration tool content types. The release adds new experimental tool search and OpenAI request policy hooks. And the OpenTelemetry gen-ai semantic conventions are updated to align with v1.41.

The 'aiagent-webapi' project template in Microsoft.Agents.AI.ProjectTemplates is updated to align with v1.3.0 of Agent Framework, updating the OpenTelemetry dependencies within the template projects as well.

    • CodeInterpreterToolCallContent
    • CodeInterpreterToolResultContent
    • WebSearchToolCallContent

  • New experimental API: OpenAIRequestPolicies extension hook for appending System.ClientModel.PipelinePolicy instances to outgoing OpenAI requests #​7495

Breaking Changes to Experimental APIs

  • WebSearchToolResultContent.Results was renamed to Outputs as part of the stabilization in #​7493, aligning with CodeInterpreterToolResultContent.Outputs. The original Results property was included in version 10.4.0 and 10.5.0; this is a binary breaking change and consumers need to update to consume the updated property.

10.5.0

HTTP Logging Middleware APIs in Microsoft.AspNetCore.Diagnostics.Middleware are now stable. This release also transfers Microsoft.Extensions.VectorData.Abstractions and Microsoft.Extensions.VectorData.ConformanceTests from the Semantic Kernel repository into dotnet/extensions, jumping from 10.1.0 to 10.5.0 for consistent versioning. The release also delivers fixes across the AI libraries, AI Evaluation, and Service Discovery.

Breaking Changes

  1. Rename VectorStoreVectorAttribute constructor parameter #​7460
    • The Dimensions parameter was renamed to dimensions (lowercase). This is a source-breaking change only — binary compatibility is preserved.
    • If you use the named argument syntax new VectorStoreVectorAttribute(Dimensions: 1536), update it to new VectorStoreVectorAttribute(dimensions: 1536).

Experimental API Changes

Now Stable

  • HTTP Logging Middleware APIs are now stable (previously EXTEXP0013): AddHttpLogEnricher<T>, IHttpLogEnricher, and RequestHeadersLogEnricherOptions.HeadersDataClasses #​7380

Experimental API Changes

Now Stable

  • IChatReducer interface — graduated from experimental to stable. The interface is now stable; concrete implementations (MessageCountingChatReducer, SummarizingChatReducer, ReducingChatClient) remain experimental. #​7235 by @​jeffhandley
  • FunctionCallContent and FunctionResultContent unsealed — changed from sealed class to class, enabling derivation. #​7229 by @​stephentoub (co-authored by @​Copilot)

Breaking Changes to Experimental APIs

  • Experimental diagnostic ID reorganization — the blanket MEAI001 diagnostic ID was split into feature-specific constants. OpenAI-specific experimental APIs now use OPENAI001, OPENAI002, or SCME0001 instead of MEAI001. Consumers who suppressed MEAI001 for OpenAI APIs may need to suppress OPENAI001/OPENAI002 instead. #​7116 by @​jeffhandley (co-authored by @​Copilot), #​7235 by @​jeffhandley

New Experimental APIs

  • Chat reduction implementations — MessageCountingChatReducer, SummarizingChatReducer, ReducingChatClient, and UseChatReducer builder extension. #​7235 by @​jeffhandley
  • OpenAI Responses/Assistants/Realtime/Image/Audio integrations — assigned feature-specific experimental diagnostic IDs (OPENAI001, OPENAI002). #​7235 by @​jeffhandley

10.5.1

Version 10.5.1 of the Microsoft.Extensions.AI packages stabilizes CodeInterpreter, WebSearch, and ImageGeneration tool content types. The release adds new experimental tool search and OpenAI request policy hooks. And the OpenTelemetry gen-ai semantic conventions are updated to align with v1.41.

The 'aiagent-webapi' project template in Microsoft.Agents.AI.ProjectTemplates is updated to align with v1.3.0 of Agent Framework, updating the OpenTelemetry dependencies within the template projects as well.

Experimental API Changes

Now Stable

The following types previously emitted the MEAI001 experimental diagnostic and are now stable.

  • CodeInterpreter and WebSearch tool content types are now stable #​7493
    • CodeInterpreterToolCallContent
    • CodeInterpreterToolResultContent
    • WebSearchToolCallContent
    • WebSearchToolResultContent
  • ImageGeneration tool content types and tool are now stable #​7476
    • ImageGenerationToolCallContent
    • ImageGenerationToolResultContent
    • HostedImageGenerationTool
    • ImageGenerationOptions
    • ImageGenerationResponseFormat (the Hosted enum value remains experimental)
    • IImageGenerator and the rest of the image generation infrastructure also remain experimental

New Experimental APIs

The following new APIs emit the MEAI001 experimental diagnostic.

  • New experimental API: HostedToolSearchTool with DeferredTools for tool-search-driven deferred tool loading #​7471
  • New experimental API: OpenAIRequestPolicies extension hook for appending System.ClientModel.PipelinePolicy instances to outgoing OpenAI requests #​7495

Breaking Changes to Experimental APIs

  • WebSearchToolResultContent.Results was renamed to Outputs as part of the stabilization in #​7493, aligning with CodeInterpreterToolResultContent.Outputs. The original Results property was included in version 10.4.0 and 10.5.0; this is a binary breaking change and consumers need to update to consume the updated property.

    WebSearchToolResultContent content = ...;
- IList<AIContent>? items = content.Results;
+ IList<AIContent>? items = content.Outputs;

10.5.0

HTTP Logging Middleware APIs in Microsoft.AspNetCore.Diagnostics.Middleware are now stable. This release also transfers Microsoft.Extensions.VectorData.Abstractions and Microsoft.Extensions.VectorData.ConformanceTests from the Semantic Kernel repository into dotnet/extensions, jumping from 10.1.0 to 10.5.0 for consistent versioning. The release also delivers fixes across the AI libraries, AI Evaluation, and Service Discovery.

Breaking Changes

  1. Rename VectorStoreVectorAttribute constructor parameter #​7460
    • The Dimensions parameter was renamed to dimensions (lowercase). This is a source-breaking change only — binary compatibility is preserved.
    • If you use the named argument syntax new VectorStoreVectorAttribute(Dimensions: 1536), update it to new VectorStoreVectorAttribute(dimensions: 1536).

Experimental API Changes

Now Stable

  • HTTP Logging Middleware APIs are now stable (previously EXTEXP0013): AddHttpLogEnricher<T>, IHttpLogEnricher, and RequestHeadersLogEnricherOptions.HeadersDataClasses #​7380
