Apache Mesos 1.3.0 Released

The latest Mesos release, 1.3.0, is now available for download. This release includes the following features and improvements:

MESOS-1763 - Support for frameworks to receive resources for multiple roles. This allows “multi-user” frameworks to leverage the role-based resource allocation in mesos. Prior to this support, one had to run multiple instances of a single-user framework to achieve multi-user resource allocation, or implement multi-user resource allocation in the framework.
MESOS-6365 - Authentication and authorization support for HTTP executors. A new --authenticate_http_executors agent flag enables required authentication on the HTTP executor API. A new --executor_secret_key flag sets a key file to be used when generating and authenticating default tokens that are passed to HTTP executors. Note that enabling these flags after upgrade is disruptive to HTTP executors that were launched before the upgrade; see ‘docs/authentication.md’ for more information on these flags and the recommended upgrade procedure. Implicit authorization rules have been added which allow an authenticated executor to make executor API calls as that executor and make operator API calls which affect that executor’s container. See ‘docs/authorization.md’ for more information on these implicit authorization rules.
MESOS-6627 - Support for frameworks to modify the role(s) they are subscribed to. This is essential to supporting “multi-user” frameworks (see MESOS-1763) in that roles are expected to come and go over time (e.g. new employees join, new teams are formed, employees leave, teams are disbanded, etc).

More than 140 other bug fixes and improvements made it into this release. For full release notes with all features and bug fixes, please refer to the CHANGELOG.
