+After some time of silence of Ditto milestone releases we are very proud to present our next one to the public.
+
+Have a look at the Milestone [0.3.0-M1 release notes](release_notes_030-M1.html). 
+
+The main changes are 
+
+* switch to [Eclipse OpenJ9](https://www.eclipse.org/openj9/) JVM in Ditto's Docker images
+* renaming of Ditto's "AMQP bridge" service to "Connectivity" due to more responsibilities for that service:
+    * managing + connecting to AMQP 0.9.1 endpoints as well as to AMQP 1.0 endpoints
+    * transforming/mapping message payloads to/from [Ditto Protocol](protocol-overview.html)
+    * for further details, have a look at our [blogpost about that](2018-04-25-connectivity-service.html)
+
+## Artifacts
+
+The new Java artifacts have been published at the [Eclipse Maven repository](https://repo.eclipse.org/content/repositories/ditto/)
+as well as [Maven central](https://repo1.maven.org/maven2/org/eclipse/ditto/).

+
+Since the last milestone of Eclipse Ditto [0.2.0-M1](release_notes_020-M1.html), the following changes, new features and
+bugfixes were added.
+
+
+## Changes
+
+### [OpenJ9 based Docker images](https://github.com/eclipse/ditto/pull/133)
+
+The official Eclipse Ditto Docker images are now based on the [Eclipse OpenJ9](https://www.eclipse.org/openj9/) JVM.
+With this JVM (cheers to the OpenJ9 developers for this awesome JVM) Ditto's containers need a lot less memory having
+similar if not better throughput.
+
+This especially comes in handy for the [Ditto sandbox](https://ditto.eclipse.org) which only has 4GB RAM and 1 CPU core ;-)
+
+### AMQP bridge renaming
+
+Ditto's former AMQP bridge service was renamed to `connectivity` as it no longer only manages AMQP 1.0 connections, see
+the [new features](#new-features).
+
+
+## New features
+
+### [AMQP 0.9.1 connectivity](https://github.com/eclipse/ditto/issues/129)
+
+The new `connectivity` service can now, additionally to AMQP 1.0, manage and open connections to AMQP 0.9.1 endpoints 
+(e.g. provided by a [RabbitMQ](https://www.rabbitmq.com) broker).
+
+### [Payload mapping to/from Ditto Protocol](https://github.com/eclipse/ditto/issues/130)
+
+The new `connectivity` service can now also map message arbitrary text or byte payload from incoming AMQP 1.0 / 0.9.1 
+connections which are not yet in [Ditto Protocol](protocol-overview.html) messages in such and can also map outgoing 
+Ditto Protocol messages (e.g. responses or events) back to some arbitrary text or byte payload.
+ 
+
+## Bugfixes
+
+### Failover and stability fixes in connectivity service
+
+The former AMQP bridge did loose the connection to AMQP 1.0 endpoints. This is now much more stable from which also the 
+new AMQP 0.9.1 connections benefit.
+
+### [Docker compose config was wrong](https://github.com/eclipse/ditto/issues/140)
+
+The entrypoint/command was pointing to a wrong `starter.jar`.
+
+
+### Various smaller bugfixes
+
+This is a complete list of the 
+[merged pull requests](https://github.com/eclipse/ditto/pulls?q=is%3Apr+milestone%3A0.3.0-M1+).
+
+
+## Documentation
+
+The documentation for the new/renamed `connectivity` service now has its own new section: 
+[Connectivity API](connectivity-overview.html).
