Full release details are available +on Launchpad: https://launchpad.net/ironic/liberty/4.2.0. + +* Deprecated the bash ramdisk + + The older bash ramdisk built by diskimage-builder is now deprecated and + support will be removed at the beginning of the "N" development cycle. Users + should migrate to a ramdisk running ironic-python-agent, which now also + supports the pxe_* drivers that the bash ramdisk was responsible for. + For more info on building an ironic-python-agent ramdisk, see: + http://docs.openstack.org/developer/ironic/deploy/install-guide.html#building-or-downloading-a-deploy-ramdisk-image + +* Raised API version to 1.14 + + * 1.12 allows setting RAID properties for a node; however support for + putting this configuration on a node is not yet implemented for in-tree + drivers; this will be added in a future release. + + * 1.13 adds a new 'abort' verb to the provision state API. This may be used + to abort cleaning for nodes in the CLEANWAIT state. + + * 1.14 makes the following endpoints discoverable in the API: + + * /v1/nodes//states + + * /v1/drivers//properties + +* Implemented a new Boot interface for drivers + + This change enhances the driver interface for driver authors, and should not + affect users of Ironic, by splitting control of booting a server from the + DeployInterface. The BootInterface is responsible for booting an image on a + server, while the DeployInterface is responsible for deploying a tenant image + to a server. + + This has been implemented in most in-tree drivers, and is a + backwards-compatible change for out-of-tree drivers. The following in-tree + drivers will be updated in a forth-coming release: + + * agent_ilo + + * agent_irmc + + * iscsi_ilo + + * iscsi_irmc + +* Implemented a new RAID interface for drivers + + This change enhances the driver interface for driver authors. Drivers may + begin implementing this interface to support RAID configuration for nodes. + This is not yet implemented for any in-tree drivers. + +* Image size is now checked before deployment with agent drivers + + The agent must download the tenant image in full before writing it to disk. + As such, the server being deployed must have enough RAM for running the + agent and storing the image. This is now checked before Ironic tells the + agent to deploy an image. An optional config [agent]memory_consumed_by_agent + is provided. When Ironic does this check, this config option may be set to + factor in the amount of RAM to reserve for running the agent. + +* Added Cisco IMC driver + + This driver supports managing Cisco UCS C-series servers through the + CIMC API, rather than IPMI. Documentation is available at: + http://docs.openstack.org/developer/ironic/drivers/cimc.html + +* iLO virtual media drivers can work without Swift + + iLO virtual media drivers (iscsi_ilo and agent_ilo) can work standalone + without Swift, by configuring an HTTP(S) server for hosting the + deploy/boot images. A web server needs to be running on every conductor + node and needs to be configured in ironic.conf. + + iLO driver documentation is available at: + http://docs.openstack.org/developer/ironic/drivers/ilo.html + + 4.1.0 =====
