滚动更新（英语：rolling update），又称滚动发行（rolling release）是指软件开发中，不断的开发软件系统模式，用来代替传统的通过重新安装新版本来代替之前版本的发行方式。而「滚动软件」，用来代替的则是需要重新安装才可以更新到新版本的软件模式。滚动更新的开发模式是一种软件发行方式，更新的开发模式和传统的发行模式有着较少的相同之处。

尽管滚动更新的软件发行模式可以任何的软件发行，但通常情况下，仅出现在少数人使用的Linux发行版。使用滚动发行的Linux发行版通常被称为「滚动发行版」。

In software development, a rolling release or rolling update development model refers to a continually developing software system; this is instead of a standard release development model which uses software versions that must be reinstalled over the previous version. Rolling release development models are one of many types of software release life cycles and, in terms of software development methodology in general, rolling release development models are less common than standard release development models in most mainstream software sectors, such as operating systems.
