Release 2026-05-18

Amazon.Lambda.Core (3.1.0)

• [Preview] Add LambdaLogger.ConfigureStructuredLogging to customize the JsonSerializerOptions used for serializing logging parameters.
• Add preview ILambdaSerializer Serializer property to ILambdaContext (default-implemented to null on net8.0+) so user code can access the serializer registered with the runtime. Marked [Experimental(AWSLAMBDA001)]; class-library mode requires an updated managed Lambda runtime to populate this property. The Experimental flag will be removed in a follow-up release once the managed runtime is deployed.

Amazon.Lambda.RuntimeSupport (2.1.0)

• Add support for handling the structured logging customization from Amazon.Lambda.Core.
• Propagate the registered ILambdaSerializer to the per-invocation ILambdaContext.Serializer. Surfaces the new preview ILambdaContext.Serializer (AWSLAMBDA001); the Experimental flag will be removed in a follow-up release once the managed runtime is deployed.

Amazon.Lambda.Annotations (2.0.1)

• Fix CS0121 ambiguity error in generated Program.g.cs when a Lambda handler has no input parameters and returns Task. The source generator now uses the unambiguous LambdaBootstrapBuilder.Create(Func<Stream, Task>) overload for this case.

Amazon.Lambda.TestUtilities (4.1.0)

• Add Serializer setter to TestLambdaContext to mirror the new preview ILambdaContext.Serializer property. Marked [Experimental(AWSLAMBDA001)]; the Experimental flag will be removed in a follow-up release once the managed runtime is deployed.

Amazon.Lambda.AspNetCoreServer (10.1.1)

• Fix InvokeFeatures.Set to bump the feature collection revision so middleware that wraps the response body (e.g. OutputCache, ResponseCompression) is properly visible to ASP.NET Core's FeatureReferences cache. Resolves #1702 where IOutputCache stored empty response bodies.

Release 2026-05-15

Amazon.Lambda.AspNetCoreServer (10.1.0)

• Add APIGatewayWebsocketApiProxyFunction (and TStartup variant) so API Gateway WebSocket APIs can be hosted via LambdaServer (DI, controllers). WebSocket events are dispatched as POST requests whose path is the RouteKey, allowing controller actions like [HttpPost()] to handle them.
• Expose ParseHttpPath, ParseHttpMethod, and AddMissingRequestHeaders as protected virtual hooks on APIGatewayProxyFunction so subclasses can customize how the API Gateway request is mapped onto the ASP.NET Core request feature.

Amazon.Lambda.AspNetCoreServer.Hosting (2.1.0)

• Add LambdaEventSource.WebsocketApi so AddAWSLambdaHosting can wire ASP.NET Core minimal APIs and controllers up to API Gateway WebSocket events.

Release 2026-05-13

Amazon.Lambda.TestTool (0.14.1)

• Fixed static assets (CSS, JS, BlazorMonaco) failing to load when ASPNETCORE_ENVIRONMENT or DOTNET_ENVIRONMENT is set to a non-Production value by always serving static files from the tool's install directory.
