On 23 April 2012 Shuttleworth announced that Ubuntu 12.10 would be named Quantal Quetzal. As this will be the first of a series of three releases before the next LTS release, Shuttleworth indicated that it will include a refreshed look, with work to be done on typography and iconography. The release takes its name from the quetzal, a species of Central American birds. Ubuntu 12.10 was released on schedule on 18 October 2012 and is Canonical's seventeenth release of the operating system. Ryan Paul, writing for Ars Technica, said in April 2012 when the name was announced "A Quetzal is a colorful bird that is common to Central America. The most well-known variety, the resplendent quetzal, is known for its beauty. The name is a good fit for Ubuntu, which aims to soar in the cloud, offer visual appeal without compromising function, and avoid smacking into closed windows." The Ubuntu Developer Summit held in May 2012 set the priorities for this release. They are forecast to include an improved boot up sequence and log-in screen, dropping Unity 2D in favor of lower hardware requirements for Unity 3D, wrap around dialogs and toolbars for the head-up display and a "vanilla" version of Gnome-Shell as an option. The release would likely include GNOME 3.6, Python 3 and the 3.5 Linux kernel.[164] It would ship with Python 3 in the image, but with Python 2 available in the repositories, via the "Python" package. The kernel will have the PAE switched on by default. In July 2012, development versions of Ubuntu 12.10 received a new combined user, session and system menu. This release also included Ubuntu Web Apps, a means of running Web applications directly from the desktop, without having to open a browser. It would use Nautilus 3.4 as its file manager, in place of the 3.5 and newer versions, to retain features deleted from later versions. In September 2012, Canonical's Kate Stewart announced that the Ubuntu 12.10 image would not fit on a compact disc, saying "There is no longer a traditional CD sized image, DVD or alternate image, but rather a single 800MB Ubuntu image that can be used from USB or DVD." However, a third-party project has created a version of Ubuntu 12.10 that fits on a CD. It uses LZMA2 compression instead of the DEFLATE compression used on the official Ubuntu DVD image. Also in late September 2012, it was announced that the version of Unity to be shipped with Ubuntu 12.10 would by default include searches of Amazon.com for searched terms. This move caused immediate controversy among Ubuntu users, particularly with regard to privacy issues, and caused Mark Shuttleworth to issue a statement indicating that this feature is not adware and labelled many of the objections "FUD" (Fear, uncertainty, and doubt). Shuttleworth stated "What we have in 12.10 isn't the full experience, so those who leap to judgement are at maximum risk of having to eat their words later. Chill out. If the first cut doesn't work for you, remove it, or just search the specific scope you want (there are hotkeys for all the local scopes)." Regardless, users filed a Launchpad bug report on the feature requesting that it be made a separate lens and not included with general desktop searches for files, directories and applications. The degree of community push-back on the issue resulted in plans by the developers to make the dash and where it searches user-configurable via a GUI-setting dialogue. Despite concerns that the setting dialogue would not make the final version of Ubuntu 12.10, it was completed and is present in the final version of 12.10. In the week prior to the stable release of Ubuntu 12.10 data-privacy advocate Luís de Sousa indicated that the inclusion of the shopping lens, installed without explicit permission of the user, violates European Directive 95/46/EC on data privacy. That directive requires that the "data subject has unambiguously given his consent" in situations where personal identifying information is sent. In reviewing Ubuntu 12.10 at the end of October 2012 for DistroWatch, Jesse Smith raised concerns about the Amazon shopping lens, saying, "it has raised a number of privacy concerns in the community and, looking over Ubuntu's legal notice about privacy does not provide any reassurance. The notice informs us Canonical reserves the right to share our keystrokes, search terms and IP address with a number of third parties, including Facebook, Twitter, Amazon and the BBC. This feature is enabled by default, but can be turned off through the distribution's settings panel." He also found that the dash provided very slow performance and that the release was "practically unusable in the VirtualBox environment". He summed up his experiences, "After a day and a half of using Ubuntu 12.10 it was an internal struggle not to wipe my hard drive and just find another distribution to review. During the first twenty-four hours Ubuntu spied on me, provided performance which was distinctly sub par, the interface regularly popped up errors (sometimes so frequently the first pop-up wouldn't have faded out of view before the next one appeared), the update notification didn't work and it wasn't possible to turn off accessibility features through the graphical interface. Adding insult to injury, the Unity dash kept locking up or losing focus while I was trying to use it and the operating system crashed more times than not while trying to shutdown or logout. Switching away from Unity to GNOME Fallback helped the performance issues I had experienced with the Dash, but it didn't remove the annoying pop-up errors and performance (while usable) still wasn't as good as I would expect. And what really makes me scratch my head is Ubuntu 12.04 worked really well on this same hardware." In early November, the Electronic Frontier Foundation made a statement on the shopping lens issue, "Technically, when you search for something in Dash, your computer makes a secure HTTPS connection to productsearch.ubuntu.com, sending along your search query and your IP address. If it returns Amazon products to display, your computer then insecurely loads the product images from Amazon's server over HTTP. This means that a passive eavesdropper, such as someone sharing a wireless network with you, will be able to get a good idea of what you're searching for on your own computer based on Amazon product images. It's a major privacy problem if you can't find things on your own computer without broadcasting what you're looking for to the world." Writing about Ubuntu 12.10 in a December 2012 review, Jim Lynch addressed the Amazon controversy: One of the desktop changes that some folks might not like is the web app link to Amazon.com ... This might come across as a bridge too far in terms of the outright commercialization of Ubuntu. And it is an eery [sic] reminder of all the garbage that gets installed on Windows PCs by default, by the hardware companies. Is this where Ubuntu is going? Will you someday boot into your Ubuntu desktop only to find tons of commercial crapware clogging up your desktop by default? I sure hope not, as it will be another reason for people to avoid Ubuntu. He concluded by saying, "Overall, Ubuntu 12.10 is a decent upgrade for current Ubuntu users. However, the inclusion of the Amazon icon on the launcher, and the discontinuation of Unity 2D might irritate some people." Support for Ubuntu 12.10 Quantal Quetzal officially ended on 16 May 2014.
Ubuntu 12.04 LTS (Precise Pangolin) is Canonical's sixteenth release of Ubuntu and its fourth long-term support (LTS) release, made available on schedule on 26 April 2012. It is named after the pangolin anteater.[144] Previous LTS releases have been supported for three years for the desktop version and five years for the server version; this release was supported for five years for both versions, with support ending on 28 April 2017. Canonical continues to offer extended security maintenance to Advantage customers for an additional two years. Changes in this release include a much faster startup time for the Ubuntu Software Center and refinements to Unity. This release also switched the default media player from Banshee back to Rhythmbox and dropped the Tomboy note-taking application and the supporting Mono framework as well. Also, the window dodge feature has been removed from the Unity launcher starting with Ubuntu 12.04. Ubuntu 12.04 incorporated a new head-up display (HUD) feature that allows hot key searching for application menu items from the keyboard, without needing the mouse. Shuttleworth said that the HUD "will ultimately replace menus in Unity applications" but for Ubuntu 12.04 at least the menus will remain. Ubuntu 12.04 is the first Ubuntu release shipped with IPv6 privacy extensions turned on by default. Ubuntu 11.10 already supported IPv6 on the desktop and in the installer (stateless address autoconfiguration SLAAC, stateless DHCPv6 and stateful DHCPv6). Like previous LTS releases, 12.04 included point releases that bundled updates to shorten downloads for users installing the release later in its life-cycle. The point releases and dates were: 12.04.1 (23 August 2012), 12.04.2 (14 February 2013), 12.04.3 (scheduled for release on 22 August 2013, but actually released on 23 August 2013), 12.04.4 (6 February 2014) and 12.04.5 (7 August 2014). Jesse Smith of DistroWatch said that many people, like he, had questioned Ubuntu's direction, including Unity, but with Ubuntu 12.04 he felt that the puzzle pieces, which individually may have been underwhelming, had come together to form a whole, clear picture. He said "Unity, though a step away from the traditional desktop, has several features which make it attractive, such as reducing mouse travel. The HUD means that newcomers can find application functionality with a quick search and more advanced users can use the HUD to quickly run menu commands from the keyboard." He wrote that Unity had grown to maturity, while indicating that he was bothered by its lack of flexibility. He did notice issues, however, especially that the HUD did not work in LibreOffice and performance in a virtual machine was unsatisfactory. He concluded that Ubuntu's overall experience was "head and shoulders above anything else in the Linux ecosystem." Jim Lynch wrote "Ubuntu 12.04 is definitely worth an upgrade if you're running an earlier version. Unity is finally coming into its own in this release, plus there are other enhancements that make upgrading worthwhile. Ubuntu is getting better and better with each release. I was one of the Unity skeptics initially, but I've come to accept it as part of Ubuntu." Jack Wallen of TechRepublic, who had strongly criticized early versions of Unity, said "Since Ubuntu 12.04 was released, and I migrated over from Linux Mint, I'm working much more efficiently. This isn't really so much a surprise to me, but to many of the detractors who assume Unity a very unproductive desktop ... well, I can officially say they are wrong. [...] I realize that many people out there have spurned Unity (I was one of them for a long time), but the more I use it, the more I realize that Canonical really did their homework on how to help end users more efficiently interact with their computers. Change is hard – period. For many, the idea of change is such a painful notion they wind up missing out on some incredible advancements. Unity is one such advancement."
The naming of Ubuntu 11.10 (Oneiric Ocelot) was announced on 7 March 2011 by Mark Shuttleworth. He explained that Oneiric means "dreamy". Ubuntu 11.10 was released on schedule on 13 October 2011 and is Canonical's 15th release of Ubuntu. In April 2011, Shuttleworth announced that Ubuntu 11.10 would not include the classic GNOME desktop as a fall back to Unity, unlike Ubuntu 11.04 Natty Narwhal. Instead, 11.10 included a 2D version of Unity as a fallback for computers that lacked the hardware resources for the Compiz-based 3D version. However, the classic GNOME desktop remained available in Ubuntu 11.10 through a package in the Ubuntu repositories. Shuttleworth also confirmed that Unity in Ubuntu 11.10 would run as a shell for GNOME 3 on top of GNOME 3 libraries, unlike in Ubuntu 11.04 where it ran as a shell for GNOME 2. Moreover, users were able to install the entire GNOME 3 stack along with GNOME Shell directly from the Ubuntu repositories; to be presented with a "GNOME 3 desktop" choice at login. During the development cycle there were many changes to Unity, including the placement of the Ubuntu button on the Launcher instead of on the Panel, the autohiding of the window controls (and the global menu) of maximized windows, the introduction of more transparency into the Dash (and the Panel when the Dash was opened) and the introduction of window controls for the Dash. In May 2011, it was announced that Pitivi would be no longer part of the Ubuntu ISO, starting with Ubuntu 11.10 Oneiric Ocelot. The reasons given for removing it included poor user reception, lack of fit with the default user-case for Ubuntu, lack of polish and the application's lack of development maturity. PiTiVi will not be replaced on the ISO with another video editor. Other changes include removing Computer Janitor, as it caused broken systems for users, and the removal of the Synaptic package manager, which can optionally be installed via the Ubuntu Software Center. Déjà Dup has been added as Ubuntu's backup program. Mozilla Thunderbird has replaced the GNOME Evolution email client. All removed applications will remain available to users for installation from the Ubuntu Software Center and repositories. Support for Ubuntu Oneiric Ocelot was officially ended on 9 May 2013.
The naming of Ubuntu 11.04 (Natty Narwhal) was announced on 17 August 2010 by Mark Shuttleworth. Ubuntu 11.04 Natty Narwhal was released on 28 April 2011. It is Canonical's 14th release of Ubuntu. Ubuntu 11.04 used the Unity user interface instead of GNOME 2 as default. The move to Unity was controversial as some GNOME developers feared it would fracture the community and marginalize GNOME Shell. The GNOME desktop environment is still available in Ubuntu 11.04 under the title Ubuntu Classic as a fallback to Unity. Ubuntu 11.04 employed Banshee as the default music player, replacing Rhythmbox. Other new applications included Mozilla Firefox 4 and LibreOffice, which replaced OpenOffice.org. The OpenStack cloud computing platform was added in this release. Starting with Ubuntu 11.04, the Ubuntu Netbook Edition was merged into the desktop edition. In reviewing Ubuntu 11.04 upon its stable release, Ryan Paul of Ars Technica said "There is a lot to like in Ubuntu 11.04, but also a lot of room for improvement." Jesse Smith of DistroWatch said "I'm of the opinion there are good features in this release, but 11.04 definitely suffered from being rushed out the door while it was still beta quality. Ubuntu aims to be novice-friendly, but this release is buggy and I think they missed the mark this time around. I'm limiting my recommendation of 11.04 to people who want to play with an early release of Unity." Support for Ubuntu 11.04 officially ended on 28 October 2012.
Named for the green three-eyed aliens. The release was frozen on August 6, 2010, with many of the Debian developers gathered at the 10th DebConf at New York City. While two architectures (alpha and hppa) were dropped, two architectures of the new FreeBSD port (kfreebsd-i386 and kfreebsd-amd64) were made available as technology preview, including the kernel and userland tools as well as common server software (though not advanced desktop features yet). This was the first time a Linux distribution has been extended to also allow use of a non-Linux kernel. The new release introduced a dependency based boot sequence, which allowed for parallel init script processing, speeding system startup.
The naming of Ubuntu 10.10 (Maverick Meerkat) was announced by Mark Shuttleworth on 2 April 2010, along with the release's goals of improving the netbook experience and a server focus on hybrid cloud computing. Ubuntu 10.10 was released on 10 October 2010 (10.10.10) at around 10:10 UTC. This is a departure from the traditional schedule of releasing at the end of October to get "the perfect 10", and a playful reference to The Hitchhiker's Guide to the Galaxy, since, in binary, 101010 is equal to the number 42, the "Answer to the Ultimate Question of Life, the Universe and Everything" within the series. It was Canonical's 13th release of Ubuntu. New features included the new Unity interface for the Netbook Edition, a new default photo manager, Shotwell, replacing F-Spot, the ability to purchase applications in the Software Center, and an official Ubuntu font used by default. Support for Ubuntu Maverick Meerkat 10.10 was officially ended on 10 April 2012.
Shuttleworth first announced Ubuntu 10.04 (Lucid Lynx) on 19 September 2009 at the Atlanta Linux Fest; Canonical released it on 29 April 2010. It was Canonical's 12th release of Ubuntu and the third long-term support (LTS) release. The new release included, among other things, improved support for Nvidia proprietary graphics drivers, while switching to the open source Nvidia graphics driver, Nouveau, by default. Plymouth was also introduced, allowing boot animations. It also included a video editor for the first time, Pitivi. GIMP was removed from the Lucid installation CD due to its professional-grade complexity and its file size. F-Spot provided normal user-level graphics-editing capabilities and GIMP remained available for download in the repositories. The distribution emphasized the increasing importance of Web services and of social networking services with integrated interfaces for posting to sites like Facebook and Twitter, complementing the IM and email integration already in Ubuntu. On 4 March 2010 it was announced that Lucid Lynx would feature a new theme, including new logos, taking Ubuntu's new visual style into account: The new style in Ubuntu is inspired by the idea of "Light". We're drawn to Light, because it denotes both warmth and clarity, and intrigued by the idea that "light" is a good value in software. Good software is "light" in the sense that it uses your resources efficiently, runs quickly, and can easily be reshaped as needed. Ubuntu represents a break with the bloatware of proprietary operating systems and an opportunity to delight to those who use computers for work and play. More and more of our communications are powered by light, and in future, our processing power will depend on our ability to work with light, too. Visually, light is beautiful, light is ethereal, light brings clarity and comfort. Historical perspective: From 2004–2010, the theme in Ubuntu was "Human". Our tagline was "Linux for Human Beings" and we used a palette reflective of the full range of humanity. Our focus as a project was bringing Linux from the data center into the lives of our friends and global family. The new theme met with mixed critical responses. Ars Technica's Ryan Paul said: "The new themes and updated color palette are nice improvement for Ubuntu ... After testing the new theme for several hours, I feel like it's a step forward, but it still falls a bit short of my expectations." Paul also noted that the most controversial aspect of the new design amongst users was the placement of the window-control buttons on the left instead of on the right side of the windows. TechSource's Jun Auza expressed concern that the new theme was too close to that used by Apple's Mac OS X: "I think Ubuntu is having an identity crisis right now and should seriously consider changing several things in terms of look and feel to avoid being branded as a Mac OS X rip-off, or worse, get sued by Apple." Auza also summarized Ubuntu user feedback: "I believe the fans are divided right now. Some have learned to love the brown color scheme since it uniquely represents Ubuntu, while others wanted change." The first point release, 10.04.1, was made available on 17 August 2010, and the second update, 10.04.2, was released on 17 February 2011. The third update, 10.04.3, was released on 21 July 2011, and the fourth and final update, 10.04.4, was released on 16 February 2012. Canonical provided support for the desktop version of Ubuntu 10.04 until 9 May 2013 and for the server version until 30 April 2015.
Ubuntu 9.10 (Karmic Koala), released on 29 October 2009, was Canonical's 11th release of Ubuntu. It was supported until April 2011. In an announcement to the community on 20 February 2009, Mark Shuttleworth explained that 9.10 would focus on improvements in cloud computing on the server using Eucalyptus, saying "... a Koala's favourite leaf is Eucalyptus", as well as further improvements in boot speed and development of the Netbook Remix. The initial announcement of version 9.10 indicated that this release might include a new theme, but the project was delayed to version 10.04, and only minor revisions were made to the default theme. Other graphical improvements included a new set of boot up and shutdown splash screens, a new login screen that transitions seamlessly into the desktop and greatly improved performance on Intel graphics chip-sets. In June 2009, Canonical created the One Hundred Paper Cuts project, focusing developers to fix minor usability issues. A "paper cut" was defined as, "a trivially fixable usability bug that the average user would encounter on his/her first day of using a brand new installation of the latest version of Ubuntu Desktop Edition." The desktop installation of Ubuntu 9.10 replaced Pidgin with Empathy Instant Messenger as its default instant messaging client. The default filesystem is ext4, and the Ubuntu One client, which interfaces with Canonical's new online storage system, is installed by default. It introduced Grub 2 beta as default bootloader. It also debuted a new application called the Ubuntu Software Center that unifies package management. Canonical stated their intention for this application to replace Add/Remove Programs (gnome-app-install) in 9.10 and possibly Synaptic, Software Sources, Gdebi and Update Manager in Ubuntu 10.04. Karmic Koala also includes a slideshow during the installation process (through ubiquity-slideshow) that highlights applications and features in Ubuntu.
Ubuntu 9.04 (Jaunty Jackalope), released on 23 April 2009, was Canonical's tenth release of Ubuntu. Support ended on 23 October 2010. New features included faster boot time and integration of web services and applications into the desktop interface. Because of that, they named it after the mythical jackalope. It was the first release named after a mythical animal, the second being Utopic Unicorn. It had a new usplash screen, a new login screen and also support for both Wacom (hotplugging) and netbooks. It also included a new notification system, Notify OSD, and themes. It marked the first time that all of Ubuntu's core development moved to the GNU Bazaar distributed version control system. Ubuntu 9.04 was the first version to support the ARM architecture with native support for ARMv5EL and ARMv6EL-VFP.
Named for the wind up binoculars in the Toy Story movies. One architecture was added in this release: ARM EABI (or armel), providing support for newer ARM processors and deprecating the old ARM port (arm). The m68k port was not included in this release, although it was still provided in the unstable distribution. This release did not feature the FreeBSD port, although much work on the port had been done to make it qualify it did not meet yet the qualification requirements for this release.
