Rolling release
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 software, instead, is continually updated, in contrast to standard release software which is upgraded between versions. 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.
