+The Orekit team is happy to welcome a new PMC member: Sébastien Dinot (@sdinot).
+
+Sébastien has been immersed in the free and open source software ecosystem
+since 1998. In 2013, he set up the FOSS governance of CS GROUP and its OSPO
+(Open Source Program Office), which he has been running ever since.
+
+Although Sébastien has no expertise in either space dynamics or Java
+development, he has been involved in the Orekit project since 2008, at various
+levels:
+* proposal and deployment of new tools (GitLab, SonarQube, Discourse) and
+  development best practices (CI/CD, quality assurance);
+* administration of the collaborative development platform;
+* creation and maintenance of the website;
+* ensuring the smooth running of the community, proposing changes in the
+  governance of the project.
+
+In addition, Pascal Parraud, who will be retiring very soon, has announced
+that he is leaving the Orekit PMC. We would like to warmly thank Pascal for
+his continuous involvement in the project since 2008 and his valuable
+contributions. We wish him a long and happy retirement, full of enjoyable
+moments. Pascal, we will miss you.
+
+The full list of Orekit PMC members as of 2025-04-04 is therefore:
+- Anne-Olivia Biramben (CS GROUP)
+- Bryan Cazabonne (Airbus Defence and Space)
+- Paul Cefola (University at Buffalo)
+- Sébastien Dinot (CS GROUP)
+- Frank Dreger (European Space Agency - ESOC)
+- Hank Grabowski (Independent Expert)
+- Sébastien Herbinière (Thales Alenia Space)
+- Petrus Hyvönen (Swedish Space Corporation)
+- Yannick Jeandroz (Airbus Defence and Space)
+- Maxime Journot (CS GROUP)

+- Luc Maisonobe (Thales Alenia Space)
+- Guillermo Ortega (European Space Agency - ESTEC)
+- Mark Rutten (InTrack Solutions)
