A Linux distribution release changes more than the version number on an installation image. It can bring new hardware support, replace desktop components, change upgrade requirements and start a new security maintenance period. The release date tells you when a version arrived. The support deadline tells you how long you can keep using it without arranging another source of maintenance.
This page covers distribution releases, support windows and the decisions that follow them. The dated snapshot below uses October 23, 2026 as its reference point. For help choosing between distributions rather than tracking their maintenance, start with how to choose a Linux distribution.
Linux Distribution Support Deadlines
Support dates need labels. Standard maintenance, long term support and paid extended coverage are not interchangeable. The table separates those phases where the projects publish different deadlines; it is a planning reference, not a promise that every installed package receives identical coverage.
| Distribution and release | Published support deadline | What to check |
|---|---|---|
| Ubuntu | 26.10: July 2027 26.04 LTS: May 2031 24.04 LTS: May 2029 22.04 LTS: May 2027 |
These are standard security maintenance deadlines. Repository coverage and optional extended maintenance differ; check Canonical’s Ubuntu lifecycle and coverage table. |
| Linux Mint | 21 series: April 2027 22 series: April 2029 |
Point releases within each listed series share their support deadline. The Linux Mint supported release matrix also identifies editions and package bases. |
| Debian | 13 “Trixie”: full support until August 9, 2028; LTS until June 30, 2030 12 “Bookworm”: LTS until June 30, 2028 11 “Bullseye”: published LTS deadline passed on August 31, 2026 |
Distinguish regular support, LTS and third party extended LTS in the Debian release lifecycle table. |
A deadline given only as a month should remain a month in your planning notes. Do not turn “April 2027” into an invented final day. Set an earlier migration date instead, leaving time to resolve application or hardware problems.
For Ubuntu, the longer dates advertised for Ubuntu Pro and the Legacy add-on belong to different coverage arrangements. Do not read them as an automatic extension of standard maintenance for every installation. Check the release, repositories and services actually in use before deciding that a machine can remain unchanged.
Release Announcements, Betas and Scheduled Dates
A development schedule records intent. A final release announcement records delivery. That distinction matters when a project moves its launch date, publishes a release candidate or makes installation images available for testing.
Fedora Linux 44 reached general availability on April 28, 2026, confirmed in the Fedora Project Leader’s release announcement. That is a delivered release milestone, not a forecast.
Fedora Linux 45 Beta became available on September 15, 2026. The Fedora 45 Beta announcement identifies it as a prerelease and describes the testing images. A beta announcement should never be relabelled as a final release simply because the version number looks ready.
The Fedora 45 release schedule illustrates another distinction: it includes alternative final target dates and explicitly marks the projected end of life as changeable. Treat those entries as scheduling information, not proof that a release shipped or that a provisional deadline became final.
When assessing a release story, check whether it concerns a proposal, an accepted change, a beta, a release candidate or general availability. Those stages answer different questions. An accepted feature can still arrive later than expected, and an installation image can exist before an upgrade is suitable for your main computer.
What Different Linux Release Models Mean
Fixed Releases and Long Term Support
A fixed release provides a named version with a defined maintenance period. Routine package updates maintain that version; a distribution upgrade moves the installation to another release. Long term support prioritises keeping a supported software base usable for longer, rather than replacing every component whenever upstream publishes something new.
The practical choice is about maintenance capacity. A workstation with a tightly controlled application stack may benefit from fewer major transitions. A machine that needs newer hardware support may justify a newer release sooner. Neither choice removes the need to install security updates.
Point Releases
A point release is an update within an existing release family, not necessarily a new support generation. Linux Mint’s published matrix makes this visible: versions 22, 22.1, 22.2 and 22.3 all have the same April 2029 deadline.
That means downloading a newer point release does not buy another full support term. It may still be the sensible installation image, but the maintenance clock belongs to the release family. Check the deadline rather than counting digits after the decimal point.
Rolling Releases
A rolling distribution replaces the usual major version upgrade cycle with continuing package updates. Arch Linux also requires attention to update consistency: its system maintenance guidance recommends regular full upgrades and states that partial upgrades are unsupported.
No recurring version migration does not mean no maintenance. Rolling releases shift the work into regular updates, reading notices and handling changes as they arrive. Choose that model because it fits your working habits, not because it sounds like a way to avoid updating.
What a New Distribution Release Changes
Read release notes for consequences, not just component version numbers. Changes to storage, authentication, encryption, boot behaviour or supported processor architectures deserve more attention than a refreshed wallpaper. The wallpaper rarely stops a computer booting.
Separate distribution changes from upstream announcements, too. A new Linux kernel release does not mean your distribution immediately installs it, and a desktop release does not mean every distribution ships the same configuration. Our Linux kernel release coverage follows that separate layer.
Before upgrading a desktop, identify the parts you cannot afford to lose: working Wi-Fi, external monitors, suspend, printing, audio devices and any required proprietary driver. Use the Linux hardware compatibility guide to organise those checks rather than assuming that a newer release will behave identically.
For development and server systems, review application dependencies and service configuration. A newer language runtime can help one project while breaking another. A successful boot proves the operating system starts; it does not prove your workload still works.
Plan an Upgrade Before Support Runs Out
Begin with an inventory: the installed distribution release, its support phase, enabled repositories and applications that depend on outside vendors. Record a migration target as well as the published deadline. A deadline without a plan is just a calendar notification waiting to become annoying.
For a personal computer, preparation can be short. For a server or shared workstation, include service owners, recovery access and a maintenance window. In either case, use the release’s documented upgrade path rather than assuming that skipping versions is supported.
- Read the release notes. Check known problems, removed packages, architecture changes and upgrade restrictions.
- Prepare recovery. Save files, configuration and anything needed to regain access if the upgrade fails.
- Check outside repositories. Confirm compatibility and follow the distribution’s instructions for disabling or replacing them.
- Test important tasks. Verify applications, networking and attached devices, not just the login screen.
- Leave time for repairs. Upgrade before the final support deadline rather than making that date your first attempt.
A backup needs a usable restore path. Check that recovery media boots and that important files can actually be retrieved. The guide to backing up and restoring a Linux desktop covers that preparation without turning every release announcement into a recovery manual.
A clean installation is another option when changing distributions or replacing an installation with years of accumulated changes. Compare the work of reinstalling applications and restoring settings against the work of upgrading in place. Our Linux installation guide covers the installation process separately.
When a Support Deadline Has Already Passed
Treat an expired maintenance period as a task to resolve, even if the machine still appears to work. Establish whether another maintenance arrangement covers that exact release and workload. An archive containing old packages is not, by itself, evidence of continuing security maintenance.
Avoid improvised repository mixing to make an expired installation look current. Choose a documented upgrade path, a clean installation or a verified extended support arrangement. For an exposed service, review whether it should remain accessible while you prepare the migration.
After moving to a supported release, keep routine patching separate from the next major upgrade decision. The guide to Linux security updates and automatic patching covers ongoing maintenance. A long support window gives you more time between migrations; it is not permission to ignore the updates in between.
