Over-the-air updates to Ubuntu Phone

Users of the Ubuntu Phone will automatically receive all features of Ubuntu 15.10, demonstrating for the first time the integration of Ubuntu’s famous flow of updates to this new ecosystem. Some elements of 15.10 have already been delivered to phone users.

Developer experience for Ubuntu Core and the Internet of Things

Ubuntu Core is a tiny rendition of Ubuntu that uses a transactional update and rollback system for apps and the the OS itself. This release of Ubuntu includes the latest version of Snapcraft, the developer tool that makes it easy to create a “snap” for Ubuntu Core.

Snapcraft is a one-stop tool to make packages of existing applications, or snaps, from source or classic Ubuntu packages. Learn more about Ubuntu Core and Snapcraft at https://developer.ubuntu.com/en/snappy/.

For ‘makers’, Ubuntu Make now has support for more platforms – now 20 versus 14 in 15.04. Ubuntu Make provides essential tools which are always fresh from the upstream providers, and a thorough testing framework so developers can be assured of a smooth experience. More information is available at https://wiki.ubuntu.com/ubuntu-make.

On the desktop

Ubuntu has been pre-installed on millions of PCs worldwide and remains one of the world’s most popular, easy-to-use and reliable operating systems available today. Ubuntu is the high-end developer platform of choice, with Nvidia, Dell and other companies launching workstations for machine learning, visualisation and general purpose development on Ubuntu. The Dell XPS 13 and Precision M800 mobile workstation both demonstrate the focus Canonical, and its partners, have on bringing next-generation tools to Ubuntu developers.

In 15.10, Unity8 is demonstrating Canonical’s convergence vision as a tech preview. Users can log into a Unity8 session on the desktop, experience the new features, and cleanly revert to the default Unity7 experience. The feature set of Unity8 now includes the important windowed mode for Desktop users, which allows users to multi-task between multiple running apps. Mobile apps such as the Music player and the Deko email client have added support to cover small form-factor devices and large screen Desktops. Ubuntu 15.10 also has improved support for developers of traditional apps that want to bring these apps into Unity8.

Ubuntu Kylin

Ubuntu Kylin users in China will benefit from all of the improvements in 15.10, such as input methods which provide a faster, more elegant Chinese experience. Users are now able to input pinyin directly in the Ubuntu Dash to search. Fewer keystrokes means faster searching! There are also UI improvements to Ubuntu Kylin Software Center and Youker Assistant for more consistent look and feel.

New in 15.10 (Wily Werewolf)

Canonical’s OpenStack Autopilot now GA

Full high availability of all cloud controller services, deployed using best practice architecture based on available hardware resources
Smart automated scale out that re-architects cloud controller services as hardware resources are added
Full integration of Open Daylight SDN controller
Choice of Swift or Ceph for object storage
New with 15.10, Canonical is debuting its newly launched Ubuntu OpenStack cloud deployer and management tool – OpenStack Autopilot – the most powerful and easiest way to deploy scale and manage Ubuntu OpenStack clouds without the complexity and costs associated with major cloud projects.

The new service, launched alongside Ubuntu 15.10, has been created to allow businesses to build and manage Ubuntu OpenStack clouds quickly, easily without the need for expensive, hard to find OpenStack cloud architects.

Autopilot has been built using the insight, experience and tools that reside within the OpenStack Interoperability Lab (OIL), the world’s only Interoperability Lab in which hundreds of OpenStack clouds are built per day using technologies from over 35 Canonical partners. The reference architecture used has been developed over the last 4 years based on Canonical experience supporting more OpenStack clouds in production than any other OpenStack distribution company.

Autopilot deploys, manages and scales Ubuntu 14.04 LTS and Ubuntu OpenStack Kilo. It has been designed to fully support in place upgrades between releases.

“One of the biggest issues organisations using OpenStack face is how to scale their clouds in line with expansion without having to employ expensive cloud architects to manually re-design them. Autopilot offers enterprises a smart, way to scale their cloud technically and financially.” said Shawn Madden, Autopilot Product Manager at Canonical, “We have built Autopilot to deliver superior scale and economics in a simple to use package.”

Ubuntu is the most widely used cloud platform and Ubuntu OpenStack the most widely deployed OpenStack cloud distribution – 57% according the latest Linux Foundation Survey. As such, many companies are looking seriously at OpenStack cloud solutions as the means to simplify cloud deployments whilst allowing them to scale rapidly.

Ubuntu OpenStack Liberty

OpenStack Liberty has been built around three key themes of Manageability, Scalability and Extensibility:

Manageability

Common library adoption
Improved configuration management
More granular Neutron security settings with RBAC support
Scalability

Initial version of Nova Cells V2 implementation to improve of single region large scale OpenStack clouds
Neutron, Nova and Cinder scale improvements
Extensibility

Support for OpenStack as the integration engine with ‘Big tent’ model of ancillary project identification
Support for containers with debut of LXD nova driver to enable workloads to be deployed as LXC containers
First release of Magnum with support for integration of Kubernetes, Swarm and Mesos
Ubuntu OpenStack Liberty is included in 15.10 and available for Ubuntu 14.04 LTS via the Ubuntu Cloud Archive.

What’s new in server

LXD comes of age

LXD, the machine container hypervisor, is now included by default within every Ubuntu server. That means every Ubuntu Server can now host hundreds of other Linux guest containers. LXD provides all of the key features expected of a modern hypervisor — image management, snapshots, live migration, Fan overlay networking, IPv4 and IPv6 support, and an industry leading security profile. Beyond the usual hypervisor features, LXD also provides an open, RESTful API, the network endpoint that any tool can use to start, stop, clone, and live migrate those containers. The first consumer of that RESTful API is the nova-compute-lxd driver — now available as a Tech Preview in Ubuntu OpenStack Liberty — which uses the LXD hypervisor to provision operating system container instances in an OpenStack private cloud, and integrates with the rest of OpenStack’s core projects (Neutron, Swift, and Ceph).

MAAS is Ubuntu’s Metal as a Service platform, capable of installing onto physical hardware any Linux or Windows operating system, and of scaling to data centers of thousands of machines. MAAS has a command line interface, a beautiful web user interface, and like LXD, a RESTful API. New for 15.10, the MAAS web interface has been redesigned, and is fully responsive in any browser on any PC or mobile device.

Ubuntu Server 15.10 ships with a v4.2 based Linux kernel, enabling the latest server hardware and peripherals available from IBM, HP, Dell, and Intel. The 15.10 kernel delivers new features inherited from upstream such as ACPI support for ARM, LSM (Linux Security Module) Stacking, and the new thermal Power Allocator governor. We also see notable Ubuntu specific achievements with fan networking for network address space expansion capability and also the introduction of a DPDK (Data Plane Development Kit) tech preview for faster packet processing in network-heavy applications.

High performance networking

New in 15.10 for telcos and enterprises with heavy networking requirements, DPDK (Data Plane Development Kit) previews. DPDK is a set of libraries and drivers for fast packet processing and with a great many high volume OpenStack deployments happening within telecoms companies, DPDK enables virtual network functions to deliver the high performance network throughput required in core network services.
