Configuration Changes
Notable changes to the /etc/heat/heat.conf [DEFAULT] section:
 * hidden_stack_tags has been added, and stacks containing these tag names will be hidden from stack-list results (defaults to data-processing-cluster, which hides sahara-created stacks)
 * instance_user was deprecated, and is now removed entirely. Nova servers created with OS::Nova::Server resource will now boot configured with the default user set up with the cloud image. AWS::EC2::Instance still creates "ec2-user"
 * max_resources_per_stack can now be set to -1 to disable enforcement
 * enable_cloud_watch_lite is now false by default as this REST API is deprecated
 * default_software_config_transport has gained the option ZAQAR_MESSAGE
 * default_deployment_signal_transport has gained the option ZAQAR_SIGNAL
 * auth_encryption_key is now documented as requiring exactly 32 characters
 * list_notifier_drivers was deprecated and is now removed
 * policy options have moved to the [oslo_policy] section
 * use_syslog_rfc_format is deprecated and now defaults to true
