v2.3.1

Summary

This patch release pins Microsoft.CodeAnalysis* packages back to 5.0.0 to work around a Roslyn regression (dotnet/roslyn#82780) introduced in 5.3.0 where source-generator interceptors are silently not applied by the compiler — causing Lambda handler wiring to not execute at runtime. This is a temporary pin until the upstream fix ships.

v2.0.0

Summary

This major release represents a complete rebranding from AwsLambda.Host to MinimalLambda, along with significant API improvements and the introduction of a new testing package. The release includes three breaking changes that require migration steps, new lifecycle handler capabilities, enhanced testing support, and improved envelope handling for multiple response types.

Key highlights:

• Framework rebranding: All packages renamed from AwsLambda.* to MinimalLambda.*
• New testing package: MinimalLambda.Testing for simplified Lambda function testing
• Lifecycle handlers: New ILambdaLifecycleContext for managing Lambda lifecycle events
• Enhanced envelopes: Support for multiple response types with shared extension methods
• API refinements: More intuitive naming conventions for core interfaces and attributes

Migration Steps

1. Framework Renamed: AwsLambda.Host → MinimalLambda

1. Update package references in your .csproj files:

   <!-- OLD -->
   <PackageReference Include="AwsLambda.Host" Version="x.x.x" />
   <PackageReference Include="AwsLambda.Abstractions" Version="x.x.x" />
   <PackageReference Include="AwsLambda.OpenTelemetry" Version="x.x.x" />
   
   <!-- NEW -->
   <PackageReference Include="MinimalLambda" Version="x.x.x" />
   <PackageReference Include="MinimalLambda.Abstractions" Version="x.x.x" />
   <PackageReference Include="MinimalLambda.OpenTelemetry" Version="x.x.x" />

2. Update namespace imports throughout your codebase:

   // OLD
   using AwsLambda.Host;
   using AwsLambda.Abstractions;
   using AwsLambda.OpenTelemetry;
   
   // NEW
   using MinimalLambda;
   using MinimalLambda.Abstractions;
   using MinimalLambda.OpenTelemetry;

3. Perform a global find-and-replace:

   • Search: AwsLambda.Host → Replace: MinimalLambda
   • Search: AwsLambda.Abstractions → Replace: MinimalLambda.Abstractions
   • Search: AwsLambda.OpenTelemetry → Replace: MinimalLambda.OpenTelemetry

2. ILambdaHostContext → ILambdaInvocationContext

1. Update interface references in handler methods:

   // OLD
   lambda.MapHandler((ILambdaHostContext context) =>
   {
       var requestId = context.AwsRequestId;
       return Results.Ok(requestId);
   });
   
   // NEW
   lambda.MapHandler((ILambdaInvocationContext context) =>
   {
       var requestId = context.AwsRequestId;
       return Results.Ok(requestId);
   });

3. [Event] Attribute → [FromEvent] Attribute

1. Update attribute usage in handler method parameters:

   // OLD
   lambda.MapHandler(([Event] MyEvent evt) =>
   {
       return Results.Ok(evt.Message);
   });
   
   // NEW
   lambda.MapHandler(([FromEvent] MyEvent evt) =>
   {
       return Results.Ok(evt.Message);
   });
