Apache Mesos had its first annual conference in collaboration with LinuxCon North America this year. I attended the conferences because its one of the major open source events of the year and also because I volunteered to be part of MesosCon program committee.
MesosCon started with a keynote from Benjamin Hindman, one of the creators of the project and Mesos team lead. One of the major news items in this keynote was the release of Apache Mesos version 0.20 later that day. This release answered a popular request from Mesos users: Docker integration.
