This release coincides with Ilka Antcheva’s end of contract. Ilka has been working with the ROOT team in the past 6 years and doing a great job with the GUI classes, the Users Guide and User Support. On behalf of the team and users I would like to thank Ilka for her contribution to the project and I wish her plenty of success in her new job.
