Release 1.3 includes a new features, improvements, and bug fixes.

New features

Support for Application Load Balancer's (ALB) events - you can now use an AWS Lambda function built with serverless-java-container as a target for ALB. serverless-java-container requires that multi-value headers support is enabled in ALB. (#214)
Gradle and Maven Assembly support - all archetypes and samples are updated to use the maven assembly plugin by default to generate a zip deployment package for AWS Lambda. This improves cold start performance for large applications. We have also included a build.gradle file in both samples and archetypes that generates the same zip file. The generated SAM templates point to the assembly zip file by default. (#133)
Spring Boot 2.x support - we have added a new aws-serverless-springboot2-archetype that makes it easy to quickly set up a new project with Spring Boot 2.x. (#181, #193)

Bug fixes

Fixed issue with Jersey not being sent all request headers. (#208)
Fixed issue with getParameterMap() method in HttpServletRequest not supporting multi-value query string parameters. (#217 thank you, @superweijiafeng)
Fixed issue with headers being treated as case sensitive after deserialization (#216 thank you, @eirikjak)

It is now possible to inject HttpServletRequest objects in Jersey's Filter objects because the framework allows proxying of the ServletRequest, ServletContext, and ServletResponse suppliers. (#211)
Updated documentation to make it easier to port existing Spring applications that rely on custom @ControllerAdvice classes. (#167)
