Saying that it's now possible to "deploy nodes using IPv6" may end up being misleading. It is now possible to deploy (Ubuntu) nodes that have IPv6 networking enabled. The actual deployment process still uses IPv4. Or a mix of IPv4 and IPv6, as the case may be.

Good point, fixed. Thank you.

You're right, thanks.

Extremely well spotted! Thanks.

We should also add a note re: https://bugs.launchpad.net/ubuntu/+source/maas/+bug/1379144 to point out that maas-proxy isn't installed by default on upgrade; if you want to use it instead of squid-deb-proxy you need to install it manually (it will remove squid-deb-proxy).

Telling you here rather than working up a branch since this hasn't landed yet :)

You might want to also include that there is support to deploy custom images, but only the API can be used to upload custom images.

Will, do, thanks both.

 Changelog
 =========
 
+1.7.0
+=====
+
+Major new features
+------------------
+
+Improved image downloading and reporting.
+  MAAS boot images are now downloaded centrally by the region controller
+  and disseminated to all registered cluster controllers.  This change includes
+  a new web UI under the `Images` tab that allows the admin to select
+  which images to import and shows the progress of the ongoing download.
+  This completely replaces any file-based configuration that used to take
+  place on cluster controllers.  The cluster page now shows whether it has
+  synchronised all the images from the region controller.
+
+  This process is also completely controllable using the API.
+
+Note:
+  Unfortunately due to a format change in the way images are stored, it
+  was not possible to migrate previously downloaded images to the new region
+  storage.  The cluster(s) will still be able to use the existing images,
+  however the region controller will be unaware of them until an import
+  is initiated.  When the import is finished, the cluster(s) will remove
+  older image resources.
+
+Increased robustness.
+  A large amount of effort has been given to ensuring that MAAS remains
+  robust in the face of adversity.  An updated node state model has been
+  implemented that takes into account more of the situations in which a
+  node can be found including any failures at each stage.
+
+  When a node is getting deployed, it is now monitored to check that each
+  stage is reached in a timely fashion; if it does not then it is marked
+  as failed.
+
+  The core power driver was updated to check the state of the power on each
+  node and is reported in the web UI and API.  The core driver now also
+  handles retries when changing the power state of hardware, removing the
+  requirement that each power template handle it individually.
+
+Node event log.
+  For every major event on nodes, it is now logged in a node-specific log.
+  This includes events such as power changes, deployments and any failures.
+
+IPv6
+  It is now possible to deploy Ubuntu nodes that have IPv6 enabled.
+  See :doc:`ipv6` for more details.
+
+Removal of Celery and RabbitMQ
+  While Celery was found to be very reliable it ultimately did not suit
+  the project's requirements as it is a largely fire-and-forget mechanism.
+  Additionally it was another moving part that caused some headaches for
+  users and admins alike, so the decision was taken to remove it and implement
+  a custom communications mechanism between the region controller and cluster
+  controllers.  The new mechanism is bidirectional and allowed the complex
+  interactions to take place that are required as part of the robustness
+  improvements.
+
+  Since a constant connection is maintained, as a side effect the web UI now
+  shows whether each cluster is connected or not.
+
+  XXX security for cluster to region
+
+Support for other OSes
+  Non-Ubuntu OSes are fully supported now. This includes:
+   - Windows
+   - Centos
+   - SuSE
+
+Minor notable changes
+---------------------
+
+Better handling of networks.
+  All networks referred to by cluster interfaces are now automatically
+  registered on the Network page.  Any node network interfaces are
+  automatically linked to the relevant Network.
+
+Improved logging.
+  A total overhaul of where logging is produced was undertaken, and now
+  all the main events in MAAS are selectively reported to syslog with the
+  "maas" prefix from both the region and cluster controllers alike.  If MAAS
+  is installed using the standard Ubuntu packaging, its syslog entries are
+  redirected to /var/log/maas/maas.log.
+
+  On the clusters, pserv.log is now less chatty and contains only errors.
+  On the region controller appservers, maas-django.log contains only appserver
+  errors.
+
+Static IP selection.
+ The API was extended so that specific IPs can be pre-allocated for network
+ interfaces on nodes and for user-allocated IPs.
+
+Pronounceable random hostnames.
+ The old auto-generated 5-letter names were replaced with a pseudo-random
+ name that is produced from a dictionary giving names of the form
+ 'adjective-noun'.
+
+Bugs fixed in this release
+--------------------------
+XXX Full milestone list here.
