Ubuntu will make a new release every six months. In addition, we may make an Enterprise Release every 12 to 24 months, which will receive additional testing.

Ubuntu releases work on a time-based release schedule. We release Ubuntu every six months. While that requires an almost superhuman effort, we have the advantage of a core team of full time Ubuntu contributors who do an excellent job of the base Ubuntu platform. We then depend on contributions from the community (that's you by the way) to make each release broader, slicker and more polished than we could alone.

Each Ubuntu release is supported for 18 months with security patches, fixes for critical bugs that could cause data loss, and extra translations.

You don't have to upgrade to the next release when it comes out, you can stay on your particular release for 18 months (skipping two other releases) and continue to get security fixes on a regular basis. After that, you will want to update your computer to one of the newer versions of Ubuntu in order to continue to receive security patches.

Upgrades are supported from each release to the next. If you wish to skip a release, and then update to the latest one, then it is necessary to update the system from your existing release through each intermediate release to get to the release you wish to run.
Enterprise releases

In addition to the regular six-monthly releases, the Ubuntu team may make an Enterprise Release (based on an existing time-based release) that has received additional stabilisation, polish and translation work. These Enterprise Releases will be supported for a longer period than the standard 18 month support of the time based releases. Upgrades will be supported from enteprise release to enterprise release.
Release schedule

The following are the current planned releases:

1. Ubuntu 4.10 (The Warty Warthog): October 2004
2. Ubuntu 5.04 (The Hoary Hedgehog): April 2005
3. Ubuntu 5.10 (The Breezy Badger): October 2005

Ubuntu每六个月发行一个新版本。此外，我们每12到24个月发布一个企业版，但它需要额外的测试。

Ubuntu发行版根据时间来建立计划表。我们每六个月发行Ubuntu，为此我们需要花很大精力，好在我们有一个全职的核心团队来维护Ubuntu的

基础设施。我们依靠社区中的志愿者（也许其中就有您）作产品拓展、宣传等，这仅靠我们是不可能的。

每个Ubuntu发行版提供18个月的安全升级，修正可能造成数据丢失的BUG以及补充新的翻译内容。

当新版本发行的时候，您不必立即升级，您可以继续使用现在的版本，直到18个月以后（跳过两个发行版），打上现有的补丁，然后再升级，

这样您又可以继续接受安全升级了。

升级是每个版本都支持的。如果您希望跳过一个发行版，更新到最新的一版，那么您需要通过其他媒介来升级到您所需要的那个版本。

企业版

除了常规的每六个月的发行版，Ubuntu团队还发行企业版（基于发行计划），它需要额外的稳定性、完整性和翻译工作。这些企业版比其他发

行版提供超过18个月的支持。企业版之间的升级也被支持。

发行计划

以下是现在计划中的发行版

1. Ubuntu 4.10 (The Warty Warthog): 2004十月
2. Ubuntu 5.04 (The Hoary Hedgehog): 2005四月
3. Ubuntu 5.10 (The Breezy Badger): 2005十月
