Mesos v1.2.1 Release Notes

    • 🚀 This is a bug fix release.

    NOTE: In Mesos 1.2.1, the master will no longer allow 0.x agents to register. Interoperability between 1.1+ masters and 0.x agents has never 👍 been supported; however, it was not explicitly disallowed, either. 🚀 Starting with this release of Mesos, registration attempts by 0.x Mesos agents will be ignored.
