we had this year two external contributors (Charles Huet & Fabio Araujo https://projects.eclipse.org/projects/iot.keyple/who ). We don't have yet external committers: I expect it in the coming months.
We also had a public external extension, external to the project: https://keyple.org/external-resources/external-add-ons/terminal-plugin-by-springcard/
we also get regular feedback from the community through issues from different repositories https://keyple.org/projects-dashboard/
Some users (only a part) of the solution are officially referenced: https://keyple.org/#adopters We know that some big transport operators and ticketing integrators are fully switching on Eclipse Keyple (migrations of thousands of terminals).
Until the end of September, we will remain focused only on the completion of documentation and guides. From October we will start a new development cycle to extend the functionality. We then plan to schedule quarterly meetings open to the community.
