| Once an Ubuntu release has been completed and published, updates for it are only released under certain circumstances, and must follow a special procedure. | ||<tablestyle="float:right; font-size: 0.9em; width:40%; background:#F1F1ED; margin: 0 0 1em 1em;" style="padding:0.5em;"><<TableOfContents>>|| {{{#!wiki warning SRU documentation has moved to https://documentation.ubuntu.com/project/SRU/stable-release-updates/index.html See the announcement: https://lists.ubuntu.com/archives/ubuntu-devel/2024-August/043090.html }}} |

| In contrast to pre-release versions, official releases of Ubuntu are subject to much wider use, and by a different demographic of user. During development, changes to the distribution primarily affect developers, early adopters and other advanced users, all of whom have elected to use pre-release software at their own risk. Users of the official release, in contrast, expect a high degree of stability. They use their Ubuntu system for their day-to-day work, and problems they experience with it can be extremely disruptive. Many of them are less experienced with Ubuntu and with Linux, and expect a reliable system which does not require their intervention. Therefore, when changes are necessary, both a strong rationale and a low risk of regressions must be provided in order to avoid exposing users to inappropriate risks. |
