The first Ubuntu release, for example, was [[#0410|Ubuntu 4.10]] and was released on 20 October 2004.<ref name="aboutUbuntu">{{Citation |title=The story of Ubuntu |url=https://ubuntu.com/about |work=Ubuntu |access-date=2023-08-12}}</ref><ref name="wartyRelease"/> Consequently, version numbers for future versions are provisional; if the release is delayed until a different month (or even year) than planned, the version number will change accordingly.<ref name="timeBasedReleases">{{Cite web |url=https://wiki.ubuntu.com/TimeBasedReleases |title=TimeBasedReleases |work=Ubuntu Team Wiki |publisher=Canonical Ltd. |access-date=27 August 2010}}</ref>

==Version end-of-life== After each version of Ubuntu has reached its [[End-of-life (product)|end-of-life]] time, its [[Software repository|repositories]] are removed from the main Ubuntu servers and consequently the mirrors.<ref>{{Cite mailing list |url=https://lists.ubuntu.com/archives/ubuntu-mirrors-announce/2007-May/000010.html |title=Old packages from unsupported Ubuntu releases will be removed from archive.ubuntu.com |last=Moffitt |first=Nick |mailing-list=ubuntu-mirrors-announce |date=31 May 2007 |access-date=1 December 2008}}</ref> Older versions of Ubuntu repositories and releases can be found on the old Ubuntu releases website.<ref name="oldrepos">{{Cite web |url=http://releases.ubuntu.com/ |title=Ubuntu Releases |publisher=Ubuntu |access-date=11 August 2008}}</ref><ref>{{Cite web|url=http://old-releases.ubuntu.com/releases/ |title=Old Ubuntu Releases |publisher=Old-releases.ubuntu.com |access-date=17 July 2013}}</ref>

==Naming convention== Ubuntu releases are also given [[code name]]s, using an adjective and an animal with the same first letter{{snd}}an [[alliteration]]{{snd}}''e.g.'', "[[#0606|Dapper Drake]]". With the exception of the first two releases, code names are in alphabetical order, and except for the first three releases, the first letters are sequential, allowing a quick determination of which release is newer. As of [[#1710|Ubuntu 17.10]], the initial letter "rolled over" and returned to "A". Names are occasionally chosen so that animal appearance or habits reflects some new feature, ''e.g.'', "Koala's favourite leaf is Eucalyptus"; see {{slink||Ubuntu 9.10 (Karmic Koala)}}. Ubuntu releases are often referred to using only the adjective portion of the code name, ''e.g.'', "[[#0704|Feisty]]".<ref name="devCodeNames">{{Cite web |url=https://wiki.ubuntu.com/DevelopmentCodeNames |title=DevelopmentCodeNames |work=Ubuntu Team Wiki |publisher=Canonical Ltd. |access-date=8 May 2009}}</ref>

Similar to [[UserLinux]] and unlike other distros at the time—which had the user choose the apps to install—the Debian-based Ubuntu curated "one best FOSS app" for each category, minimizing the amount of questions asked by the installer and the disk space used. Alternatives and additional software could be installed through Debian's [[APT (software)|Advanced Package Tool (APT)]], which featured automatic dependency resolution, a feature then only found in commercial and professional Linux distributions. Ubuntu's competitors in the consumer-friendly free-of-charge distributions segment required the user to work out such dependencies themselves and did not use the APT dependency resolution tools due to Debian's notorious complexities and hard installation process, which Ubuntu managed to simplify.<ref name="20th"/>

Paul also criticized Ubuntu's search integration for disadvantages compared to using Beagle—which he found more feature-complete, supported by bundled software, and comparable to the search experiences of other operating systems.<ref>{{Cite web |last=Paul |first=Ryan |date=2008-05-08 |title=The heron has landed: a review of Ubuntu 8.04 |url=https://arstechnica.com/information-technology/2008/05/hardy-heron-review/ |access-date=2026-02-07 |website=Ars Technica |language=en}}</ref>

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:<ref name="UbuntuWikiLightware">{{Cite web |url=https://wiki.ubuntu.com/Brand#Light:%20Ubuntu%20is%20Lightware |title=Light: Ubuntu is Lightware |publisher=ubuntu.com |access-date=4 March 2010 |archive-url=https://web.archive.org/web/20220523203914/https://wiki.ubuntu.com/Brand#Light:%20Ubuntu%20is%20Lightware|archive-date=2022-05-23|url-status=dead}}</ref>

{{Blockquote | 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.''|Chris Jones|Light: Ubuntu is Lightware|Ubuntu Wiki}}

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."

In April 2011, Shuttleworth announced that Ubuntu 11.10 would not include the classic [[GNOME]] desktop as a fall back to Unity. 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. 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. Meanwhile, users were able to install the entire GNOME 3 stack along with [[GNOME Shell]] directly from the Ubuntu repositories.<ref name="Shuttleworth07Apr11">{{Cite web|url=http://www.markshuttleworth.com/archives/669|title=Celebrating Gnome 3.0|author=Mark Shuttleworth|access-date=19 April 2011|archive-date=14 May 2011|archive-url=https://web.archive.org/web/20110514140511/http://www.markshuttleworth.com/archives/669|url-status=dead}}</ref> During the development cycle there were many changes to Unity, including the placement of the Ubuntu button on the left Launcher instead of on the top Panel, the autohiding of the window controls (and the global menu) on maximized windows, and the introduction of window controls and more [[Alpha compositing|transparency]] into the [[Unity (user interface)#Features|Dash]] search utility.<ref>{{Cite web|url=http://www.markshuttleworth.com/archives/717|title=Dash takes shape for 11.10 Unity|date=16 August 2011|publisher=Mark Shuttleworth|access-date=21 October 2011|archive-date=6 October 2011|archive-url=https://web.archive.org/web/20111006180241/http://www.markshuttleworth.com/archives/717|url-status=dead}}</ref>

In May 2011, it was announced that [[Pitivi]] would be no longer part of the Ubuntu ISO, starting with Ubuntu 11.10 Oneiric Ocelot.

This version also includes an upgrade to GNOME 45, which replaces the top-left corner's app name display with an indicator of the workspace being used, adds a camera usage indicator, a new camera app named "Snapshot", and a new image viewer app. Sidebars are now as tall as their windows as part of design polishing.<ref>{{Citation |title=Introducing GNOME 45, "Rīga" |date=2023-09-20 |work=GNOME |url=https://release.gnome.org/45/ |access-date=2024-04-26 |language=en}}</ref>

As part of an upgrade to GNOME 46, many apps have been updated to use libadwaita and GTK4. Nautilus, the file manager, has received several quality-of-life features, and Wi-Fi settings now include an option to generate a QR code for network credentials.

[[Cheese (software)|Cheese]], a [[Photo Booth]]-like camera app, has been replaced by GNOME Snapshot in the extended install, and GNOME Games is now never bundled on install. Thunderbird is now provided as only its snap version.<ref name="NobleRelNotes"/>

Abishek of ''It's Foss News'' strongly criticized the LTS release for not changing behavior from 23.10, the last release, that by default made users unable to graphically install [[deb (file format)|.deb package]]s, the most popular format for distributing software. Combined with the App Center, a recommended application to open the package with, freezing when attempting to open a .deb file, along with .deb's being opened with the archive extractor by default in 20.04, he argued that this was indicative of Canonical resorting to sabotaging user experience to promote their own products—in this case, [[snap (software)|snap package]]s.<ref name=disappoint/> Conversely, ''It's Foss'' praised other aspects of the release as "a near-perfect upgrade". By July 15, the App Center received the ability to install .deb packages (while providing a warning), though they still cannot be managed even if installed from the App Center's store.<ref>{{Citation |last=Ankush |first=Das |title=Ubuntu 24.04 LTS Can Now Do What It Should Have Always Done |date=2024-07-15 |work=It's FOSS News |url=https://news.itsfoss.com/ubuntu-24-04-deb-install/ |access-date=2024-09-05 |language=en}}</ref>
