A rolling release refers to an update delivery model where updates are continuously delivered to users, allowing them to receive the latest features, improvements, and bug fixes without needing to wait for a major new version.
Simply having small and frequent updates doesn’t immediately make software distribution a rolling release. Developers would have to work on a single code branch instead of creating separate versions for the distribution to count as a rolling release.
Several Linux distributions, such as Arch Linux, Gentoo Linux, openSUSE Tumbleweed, Manjaro Linux, and Void Linux, utilize rolling releases for Linux patching to keep their software updated. Arch Linux and other rolling release distributions offer regularly updated ISO files that contain the latest software.
These Linux distributions offer an OS installer image file (ISO) that allows for an ISO refresh. Essentially, an ISO refresh allows a new system to utilize the most recent version of a Linux distribution rather than having to update the system with all the changes from the past few months or years. The ISO refresh mainly benefits new installations.
What is the difference between rolling release and fixed release?
Unlike a rolling release, a fixed release involves users downloading a new version of the software, which would have new iterations of the operating system kernel or desktop environments. Fixed releases are often seen in software like operating systems or open source software. These usually involve scheduled updates that roll out at specific intervals, such as annually or semi-annually.
The main advantage of a fixed release over a rolling release is stability, as each software version undergoes thorough testing before deployment to minimize bugs and other unexpected issues. On the other hand, this method can sometimes leave users waiting longer for fixes, and the update process might take longer since the update files would be larger and require more time to install.
What are the advantages of a rolling release?
-
Access to new features
Users benefit from the latest features and enhancements as soon as they’re developed, keeping their software up-to-date.
-
Simpler updates
Since updates are continuously deployed in increments, system-wide upgrades, which can be disruptive and time-consuming are unnecessary.
-
Frequent patching
Bugs and security vulnerabilities can get patched out promptly since developers can push fixes without waiting for a major release.
-
Customizability
Rolling release systems are often designed to be modular, allowing users to install and configure the software they desire.
What are the disadvantages of a rolling release?
-
Stability issues
New updates often risk introducing bugs, especially if new software hasn’t been thoroughly tested in all scenarios.
-
Requires more maintenance
Continuous updates require regular system maintenance and vigilance to prevent potential conflicts or issues.
Simplifying software updates with patch management
Rolling releases are a useful method of delivering software updates despite the potential for occasional instability that comes with continuous updates. Patch management software ensures these updates are quickly identified, downloaded, and deployed. It simplifies the software update process with automation and granular control over deployments. Utilizing patch management software minimizes disruptions, streamlines processes, and ensures that updates are pushed out consistently.
