Version 1.2 of the Mesosphere Datacenter Operating System (DCOS) is now generally available, complete with new DCOS services and newer versions of Mesos and Marathon.
Here's what's new in DCOS 1.2:
Updated CoreOS to version 723.3.0, which includes OpenSSL Security fixes.
Integrated Mesos 0.23.
Updated to native Marathon version 0.10.
New DCOS services: Elasticsearch, Riak,, ArangoDB and Basho.
Over 90 other fixes and enhancements.
Should you get stuck while using the DCOS, remember the following tips:
As always, the documentation is your friend.
If you don't find it in the docs, join our public Slack community where you can hang out with fellow DCOS users, Mesosphere engineers and folks from the product team.
We also have a private Intercom chat session embedded in the DCOS web interface. Click the chat icon in the bottom-left side of the page to start an Intercom chat with a member of the Mesosphere team.
If you have not yet tried out DCOS, have a look at the getting-started guide to learn the basics of installing the free Community Edition. We wish you well in using DCOS 1.2 and look forward to answering your questions on Slack or Intercom!
