Release Notes

dotnet/extensions (Microsoft.Extensions.AI)

v10.5.0

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

open-telemetry/opentelemetry-dotnet (OpenTelemetry)

v1.15.3

Release details: 1.15.3

• Breaking change: Fixed tracestate parsing to reject keys that do not
  begin with a lowercase letter, including keys beginning with digits, to
  align with the W3C Trace Context specification.
• Breaking change: Fixed an insecure disk retry default for OTLP export.
  Disk retry now requires OTEL_DOTNET_EXPERIMENTAL_OTLP_DISK_RETRY_DIRECTORY_PATH
  when OTEL_DOTNET_EXPERIMENTAL_OTLP_RETRY=disk is configured.
• Improve efficiency of parsing of baggage and B3 propagation headers.
• OtlpLogExporter now uses IHttpClientFactory on .NET 8+.
• Fixed an issue in OTLP/gRPC retry handling where parsing gRPC status.
• Fixed OTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT not being applied.
• Fixed baggage and trace headers not respecting the maximum length in some cases.
• Fixed BaggagePropagator to trim optional whitespace (OWS) around =
  separators when parsing the baggage header.
• Fixed BaggagePropagator to strip baggage properties from values when
  parsing the baggage header.
• Fixed OTLP persistent storage clean-up handling for malformed filenames.
• Fixed resource leak in batch and periodic exporting task workers for Blazor/WASM.
• Fixed LogRecord.LogLevel to preserve LogLevel.None.
• Fixed OTEL_TRACES_SAMPLER_ARG handling for out-of-range values.
• Fixed an issue with OTLP disk retry storage where metrics and logs used the
  traces storage directory.
• Fixed full OTLP endpoint being logged by internal diagnostics.
• Improve efficiency of parsing of baggage, B3 and Jaeger propagation headers.
• Hardened Zipkin exporter memory usage for endpoint caching and array tag
  serialization.
