The Obeo Designer Early Access Program (EAP) provides free access to development versions (milestones) of Obeo Designer and Sirius to make it easy for early adopters to test new features and give us feedback in a more timely manner.
The versions of all the components in the milestone builds (Sirius, but also all its dependencies, including the Eclipse platform) are snapshots of work in progress, and do not correspond to official released versions. Some features might not always work as expected.
These milestone builds are provided for testing purposes and should not be used in production, as they are not supported. Note that due to the way Sirius works, opening existing Sirius projects with an EAP build may alter the files in a way that make them impossible to re-open with earlier, released versions of Obeo Designer or Sirius. When testing an EAP build, use a copy of your projects to keep the original unmodified.
