dotnet/extensions v10.5.0

on GitHub

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
