Nextcloud 33 End of Life: Maintenance Ends February 17, 2027
Nextcloud 33 (Hub 26 Winter) is supported until February 17, 2027. That is the "Supported Until" date for 33 in Nextcloud's own Maintenance and Release Schedule, one year after Nextcloud 33 was released on February 18, 2026. Nextcloud supports every major version for one year through monthly maintenance releases. When a major version reaches end of life it receives no further bug fixes or security updates.
The versions Nextcloud maintains now
| Version | Name | Released | Supported until |
|---|---|---|---|
| 35 | Hub 26 Summer | September 16, 2026 | September 15, 2027 |
| 34 | Hub 26 Spring | June 9, 2026 | June 8, 2027 |
| 33 | Hub 26 Winter | February 18, 2026 | February 17, 2027 |
New major versions ship every four months and each is supported for one year, so three majors overlap at any time. Nextcloud 32 and every earlier major version are already end of life. When a critical bug or vulnerability affects more than one maintained major, Nextcloud backports the fix to each of them; after February 17, 2027, 33 is no longer one of them. Every version is on the Nextcloud page.
Nextcloud Enterprise: a longer maintenance life cycle
The one-year window is the community schedule. Nextcloud's Administration Manual notes that support for major releases may be extended through enterprise subscriptions from Nextcloud GmbH, and Nextcloud's pricing page lists the maintenance life cycle per subscription: 1 year for Standard, 5+ years for Premium and Ultimate. Nextcloud does not publish a per-version end date for that longer maintenance, so if you plan to stay on 33 under a subscription, get the end date for 33 from Nextcloud in writing.
Security exposure
One entry in CISA's Known Exploited Vulnerabilities catalog names Nextcloud: CVE-2026-110447, an OS command injection in Collabora Online's Built-in CODE Server when it is used within Nextcloud. That flaw is in the Built-in CODE Server app, not in Nextcloud Server 33 itself, and CISA's required action is to apply the vendor's mitigations. It is not a reason to stay on 33 or to leave it. The reason to move is the general one: a Nextcloud Server issue found after February 17, 2027 is fixed in the maintained majors, not in 33.
What to do
- Find every Nextcloud 33 instance, including container images and appliance builds pinned to a 33 tag.
- Plan two major upgrades, not one. Nextcloud's upgrade guide says you cannot skip major releases: update to the latest 33 maintenance release, then upgrade to 34, then to 35.
- Read the Critical changes section of the release notes for each major before upgrading, as the Administration Manual recommends, and check that your installed apps support the new version.
- Back up and test the restore first, then let the background migrations finish after each major upgrade before starting the next one.
Frequently Asked Questions
When is Nextcloud 33 end of life?
Nextcloud 33 (Hub 26 Winter) is supported until February 17, 2027, according to Nextcloud's Maintenance and Release Schedule. After that day the community release schedule ships no more maintenance releases for 33, so it gets no further bug fixes or security updates.
How long does Nextcloud support each major version?
One year. Nextcloud publishes a new major version every four months and supports each one for one year through monthly maintenance releases, so three major versions are maintained at any time: currently 33, 34 and 35.
Does Nextcloud Enterprise extend support for Nextcloud 33?
Nextcloud GmbH's pricing page lists a maintenance life cycle of 1 year for the Standard subscription and 5+ years for Premium and Ultimate. Nextcloud does not publish a per-version end date for that longer maintenance, so confirm the date for 33 with Nextcloud in writing before relying on it.
What should I upgrade Nextcloud 33 to?
Nextcloud 35, the newest major version, supported until September 15, 2027. Nextcloud cannot skip major releases, so an instance on 33 upgrades to the latest 33 maintenance release, then to 34, then to 35.
