Spring Cloud AWS 2.3 is compatible with Spring Boot 2.4 and Spring Cloud 2020.0. It's a first release in the new community driven organisation awspring - which means that module group ids and package names have changed from org.springframework.cloud.aws to io.awspring.cloud.

ClientConfiguration used when initializing AWS clients, can be now defined by creating a bean with name "com.amazonaws.ClientConfiguration.BEAN_NAME".

It’s also possible to provide ClientConfiguration for particular integration by defining a bean of type ClientConfiguration and a name specific to the integration, for example for SQS client, the bean name must be sqsClientConfiguration.

In order to speed up startup times applications that do not use EC2 instance data, ContextInstanceDataAutoConfiguration is disabled by default. To enable it, set cloud.aws.instance.data.enabled to true.

AWS SDK has been upgraded to 1.11.951

For each integrated AWS service you can configure Spring Cloud AWS to use a custom endpoint using configuration properties. For example:

cloud.aws.s3.endpoint=http://localhost:4566
cloud.aws.sqs.endpoint=http://localhost:4566
cloud.aws.rds.endpoint=http://localhost:4566

Using custom endpoint can be especially useful when using Localstack in integration tests.

XML Configuration is now deprecated and is going to be removed in the major version upgrade.

In addition to global region configuration, each integration can have a different region set statically. Read More

@EnableXXX annotations have been deprecated. We recommend using Spring Boot auto-configurations.

Each service can be now enabled/disabled with enabled property.

DefaultAWSCredentialsProvider and DefaultAWSRegionProviderChain are used now by default. cloud.aws.credentials.use-default-aws-credentials-chain and cloud.aws.region.use-default-aws-region-chain properties were dropped.

To simplify project setup for applications that do not use CloudFormation support, CloudFormation related auto-configurations have been disabled by default. To enable CloudFormation support in Spring Cloud AWS you must add following dependency that will trigger ContextStackAutoConfiguration:

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-cloudformation</artifactId>
</dependency>

SES support has been extracted from context module to separate spring-cloud-aws-ses module. There is also a dedicated starter spring-cloud-aws-ses-starter.

Make RDS instance name configuration more flexible. For example, for instance name test, instead of setting cloud.aws.rds.test.username=user property you must now set:

cloud.aws.rds.instances[0].db-instance-identifier=test
cloud.aws.rds.instances[0].username=user

#495

Removed spring-cloud-aws-actuator module. Instead we recommend using the dependency to micrometer-registry-cloudwatch directly. #571
