We are pleased to announce the 1.0.0.RC2 release candidate of Spring Cloud Data Flow for Mesos, a team effort that encompasses many new features under the hood.

This release candidate builds upon the recent 1.0 GA release of Spring Cloud Data Flow. Some highlights include:

• We now run the Spring Cloud Data Flow Server as a Docker image on Marathon, a container orchestration platform for Mesos.
• This release adds features to support stream partitioning and scaling

• Currently partitioning and scaling of sinks and processors are handled by using multiple application deployments, one for each app instance, identified by an index appended to the name.
• Scaling of sources is handled by using additional application instances.

* Streams are now deployed using Marathon [Application Groups](https://mesosphere.github.io/marathon/docs/application-groups.html) so it is easier to identify the different apps making up a stream. * We have added support for launching tasks using Chronos, a fault tolerant job scheduler for Mesos.

As part of this effort we have developed a simple Java client for interacting with the Chronos API. This Java client is included in the latest 1.0.2.RELEASE version of the Spring Cloud Deployer for Mesos project…

We are pleased to announce the general availability of Spring Cloud Data Flow for Cloud Foundry version 1.0.0.RELEASE.

Spring Cloud Data Flow for Cloud Foundry provides support for orchestrating long-running (streaming) and short-lived (task/batch) data microservices on Cloud Foundry runtime.

As the successor to Spring XD, this project benefits from a much more decoupled architecture, leveraging the Spring Cloud Deployer for Cloud Foundry library, which also goes GA today. More details about Spring Cloud Data Flow’s architecture and its ecosystem can be found in this blog.

• Stream and Batch/Task Processing are the primary functionalities in Spring Cloud Data Flow and they map to Cloud Foundry Diego’s LRPs and Tasks1 respectively.

• Includes developer toolkits to build streaming and batch/task pipelines using the DSL, Shell, REST-APIs, Dashboard, Flo Designer, or any combination of those.

• Facilitates test-driven-development at individual data pipeline components along with test fixtures to develop and test "data-centric" apps in isolation.

• Leverages Cloud Foundry’s runtime capabilities such as security, metrics, operational monitoring, scaling, and reliable execution of streaming and batch/task pipelines.

We are pleased to announce the 1.0.0.RC1 release of Spring Cloud Data Flow for Cloud Foundry.

As we near completion towards a GA release in the upcoming days, this milestone brings the following improvements:

• Builds upon the 1.0.0.RC1 release of Spring Cloud Deployer Cloud Foundry, which itself builds upon Project Reactor 3.0.0.RELEASE and of CF-Java-Client 2.0.0.RELEASE

• Adds the ability to orchestrate short-lived tasks including Spring Batch Jobs in Cloud Foundry, which can be enabled as an experimental feature toggle

• Adds support for command line arguments as a separate set of properties to be passed to a Task when it’s launched

• Adds support to separate stream and task specific service bindings. This allows pinning stream and tasks specific services to stream and task applications respectively

It is my pleasure to announce that the Spring for Apache Kafka 1.0.3 maintenance release is available now.

As usual, thanks to the community for any feedback and contribution as always!

This release contains several important bug fixes, including a memory leak when using manual acknowledgments; therefore an upgrade is highly recommended.

The addressed issues can be found here.

The project now properly handles kafka messages with null payloads, which is a common use case used to "delete" a key when using Kafka Log Compaction. @KafkaListener methods will now receive a null argument for such…
