 cycle-highlights:
-  - 'Adds additional interfaces for management of hardware including Redfish
-    BIOS settings, explicit iPXE boot interface option, and additional
-    hardware support.'
-  - 'Increased capabilities and options for operators including deployment
-    templates, improved parallel conductor workers and disk erasure processes,
-    deployed node protection and descriptions, and use of local HTTP(S) servers
-    for serving images.'
-  - 'Improved options for standalone users to request allocations of bare metal
-    nodes and submit configuration data as opposed to pre-formed configuration
-    drives. Additionally allows for ironic to be leveraged using JSON-RPC as
-    opposed to an AMQP message bus.'
