Translations:ReleaseNotes/Kilo/91/en


 * Improved scaling using nested stacks
 * Heat will RPC actions on any resource that is based on a template. This should help to spread the load when dealing with large complex stacks.
 * oslo versioned objects
 * The database layer now uses oslo versioned objects to aid in future upgrades. This will allow a newly upgraded heat-engine to use a database with an older schema. Note that this will not help with upgrading to kilo.
 * New template functions
 * There is a new HOT template version "20150430" which includes two new functions "digest" and "repeat".
 * Multiregion stacks
 * http://docs.openstack.org/hot-reference/content/OS__Heat__Stack.html
 * Access to Heat services
 * The admin now has similar access to services as other projects. This is in the form of "heat-manage service-list" and via horizon. This feature reports the active heat-engines.
 * Improved validation for nova and neutron properties.
 * Pause stack creation/update on a given resource (stack hooks)
