Odoo Version Support Timeline 2026: Every Version and Its End-of-Support Date

Most teams find out their Odoo version is aging the hard way. A renewal quote climbs, or a security question lands in an audit, and nobody is sure it still gets patches. This timeline maps every version to the date its security updates stop, so you know when to bring in Odoo migration services.

What is the Odoo version support timeline in 2026?

The Odoo version support timeline gives every major version three years of standard support with security updates, then a paid extended-support period for bug fixes only. A new major version ships roughly once a year, so three versions sit in standard support at any time.

The table below uses Odoo's official dates. The column that matters most is when security updates stop, because that is the moment your system stops receiving patches for newly discovered vulnerabilities.

Odoo 19 is the latest Odoo version 2026 has been delivered, released in September 2025. The table below maps the Odoo end of life picture version by version, beginning with the date each one stops getting security updates.

Source: Odoo's official standard and extended support policy. Dates marked "planned" can shift, so confirm before you schedule a cutover.

Odoo also ships smaller online versions, such as 19.1 through 19.4, every two to three months. These run on Odoo Online only, update automatically, and are not eligible for extended support.

How does Odoo's support lifecycle actually work?

Odoo's lifecycle has three stages: standard support, paid extended support, then full retirement. Knowing which stage your version is in tells you whether you still get security patches and how urgent an upgrade is.

Standard support runs for the first three years. Per Odoo's policy it includes helpdesk support, bug fixing, and security updates. This is the only stage where your version receives new security patches at no extra cost.

Extended support begins after year three. It is a mandatory paid add-on that covers helpdesk and bug fixes where feasible. It does not include new security updates, which is the single most important thing to understand about it.

Retirement is the final stage. Once a version is fully phased out, it leaves supported hosting. Odoo 14, for example, is scheduled to be removed from Odoo.sh hosting on October 31, 2026, giving self-hosted teams a hard deadline.

One clarification helps here. Odoo does not run a formal long-term support (LTS) track like some Linux distributions. Every major version gets the same three-year standard window, so "Odoo LTS" is really just the standard-plus-extended lifecycle above.

Which Odoo version am I running, and is it still supported?

You can check your Odoo version in seconds, then read it against the table to see whether security updates are still flowing. Many teams are a version or two behind without realizing it.

To find your version, open the Settings app and look for the version number at the bottom, or check the page footer after logging in. On self-hosted systems, your administrator can confirm the exact build.

Once you know the number, the rule is simple. If you are on Odoo 17, 18, or 19 you are in standard support with security updates. If you are 16 or older, security patches have stopped and you are on paid extended support or beyond.

What does "end of support" actually mean for your business?

End of support means your Odoo version stops receiving security patches, which turns a quiet licensing detail into a real compliance and risk exposure. Bug fixes may continue under paid extended support, but new vulnerabilities go unpatched.

Running an unpatched ERP is a genuine risk. Your Odoo database holds financial, customer, and operational data, and auditors, insurers, and frameworks like ISO 27001 increasingly ask whether core systems still receive security updates.

There is a second layer many teams miss. Odoo's security updates cover the Odoo core and framework, not your custom modules. Bespoke code has always been your responsibility, so even inside standard support, custom Odoo modules need their own security review.

There is also a cost signal. From April 2026, Odoo applied a surcharge on subscriptions running on versions older than its three supported releases, so staying on version 16 or earlier now carries an extra fee on top of the security gap.

How the timeline applies to Odoo Online, Odoo.sh, and Community

The support timeline hits each deployment type differently, so your first question is not "which version" but "which edition and hosting". The dates above matter most to self-hosted and Odoo.sh Enterprise users.

Odoo Online (SaaS) users are updated automatically by Odoo, so end-of-support dates rarely bite. You are kept on a supported version by default without planning a migration.

Odoo.sh and on-premise Enterprise users control their own version. The timeline and the extended-support fee apply directly to them, so these are the teams that need to watch the dates.

Odoo Community users are a separate case. The community has no Odoo support contract, so extended support and its fee never applied. Their security patching has always depended on their own team or an implementation partner.

How iVentureTeam keeps you on a supported, secure Odoo version

We start by confirming exactly which version, edition, and hosting you run, then map your real end-of-support dates and plan an upgrade before security cover ends. No guesswork, no renewal surprises.

Our senior Odoo developers team handles the full path. Experienced Odoo consultants audit your current version and customizations, then check every third-party module for compatibility with the target release.

From there we run a staged migration with full testing before cutover. Custom code is refactored for the new framework, not left to break.

If you would rather stay current without managing it in-house, our Odoo maintenance services keep your version supported, patched, and upgraded on schedule. You get the security posture of a current release without the internal overhead.

Odoo version support in practice: a clean Odoo 12 to 15 upgrade

When EvoLogics GmbH needed to move off an aging version without disrupting operations, iVentureTeam ran the upgrade end to end. The Berlin maker of underwater acoustic modems and marine robotics wanted current, supported software.

We migrated both the database and the custom business-flow code across three major versions in this Odoo 12 to Odoo 15 upgrade. Every workflow was tested end to end.

The cutover took under a day of downtime and preserved 100% data integrity. Staying on a supported, patched version stopped being a worry for the team.

The bottom line on Odoo version support

Every Odoo version gives you three years of security updates, then a paid extended-support window that fixes bugs but not vulnerabilities, so the date that matters is when your patches stop. Track it, and upgrade before it passes.

If you are on Odoo 17, plan now for its September 2026 standard-support end. If you are Odoo 16 or older, you are already past security cover and paying more to stay there. Either way, the fix is the same: a planned upgrade to a supported release.
