Odoo Latest Version: 2026 Release, Support & Upgrade Guide

Odoo 20 is the current latest version, released in September 2026. It is available for both Community and Enterprise editions, with three years of standard support ending in September 2029. If you are running an older version, understanding the release schedule and support window is critical: Odoo charges a 25% annual legacy surcharge for any version more than three major releases old.

What is the Latest Odoo Version?

Odoo 20 is the latest stable release, launched in September 2026. Both Community and Enterprise editions are available. Community Edition is free and open-source but receives no official support contract. Enterprise Edition includes three years of standard support, security patches, and access to Odoo's managed hosting platform, Odoo.sh.

Odoo version numbers increment annually. The version number reflects the release year: Odoo 19 (2025), Odoo 18 (2024), and so on. This makes it straightforward to track which major release you are running and when it will reach end-of-life.

Prior to Odoo 20, the most recent version was Odoo 19, released in October 2025. Odoo 18 was released in October 2024. The pattern is consistent: one major release per year, always in September or October.

If you are deployed on Odoo.sh (SaaS), your instance will be running Odoo 20. If you self-host, you must manually manage upgrades. Many companies deploy multiple versions simultaneously for testing before cutover.

Odoo Version Release Schedule & Cadence

Odoo releases one major version per year. Every release happens in September or October, with minor updates and patches following throughout the year. This predictable cycle allows you to plan upgrades and budget for retraining and integration work.

Odoo's release schedule is public and documented on their release notes page. You can access release notes for every version from Odoo 9 onwards, including detailed changelogs and module-by-module feature updates. Enterprise customers receive roadmap visibility two quarters in advance, giving you time to test compatibility with custom modules.

Minor updates (e.g., Odoo 20.1, 20.2) are released every 2-3 months within a major version, typically containing bug fixes and non-breaking improvements. Security patches are released as needed to address vulnerabilities.

The timing of releases (September-October) roughly aligns with accounting year-end in many regions. This is intentional: it allows businesses to prepare for new fiscal-year processes in the new Odoo version.

How to Check Your Current Odoo Version

You can check your Odoo version in three ways depending on your deployment type.

On Odoo.sh (SaaS), log in to your instance, go to Settings, then About. The version number is displayed prominently at the top of the About page.

On a self-hosted instance, go to Settings, then About from the same menu. The version, build number, and database UUID are all shown. This is the fastest way if you have access to the Odoo interface.

On the command line for a self-hosted instance, SSH into the server and run: grep -i version /opt/odoo/odoo/release.py (or wherever your Odoo installation is located). This returns the version string directly without logging in.

If you cannot access your instance, contact your hosting provider. They can confirm your version and tell you how long support is remaining. If you are on Odoo.sh, Odoo provides account dashboards showing version, remaining support life, and scheduled maintenance windows.

Odoo Version Support Lifecycle (Standard vs Extended)

Every Odoo version receives three years of standard support starting from its release date. During those three years, you receive security patches, bug fixes, and the ability to file support tickets with Odoo.

Here is the support timeline for current and recent versions:

After the three-year support window closes, Odoo no longer provides security patches or bug fixes. You can still run the version, but you assume all security and compatibility risk. Odoo recommends upgrading before or shortly after EOL.

If you are still running a version more than three major releases old (e.g., Odoo 16 or earlier when Odoo 20 is current), you pay a 25% annual legacy surcharge on your Enterprise subscription. This surcharge is Odoo's financial incentive to migrate. For a company paying $5,000/year in support fees, a legacy surcharge adds $1,250 annually.

Community Edition has no official support contract, so no legacy surcharge applies. However, Community users on very old versions are at serious security risk and should upgrade to stay current.

Community vs Enterprise: Version Availability & Support

Both Community and Enterprise editions receive the same Odoo 20 release, but support and feature availability differ.

Community Edition is free and open-source. You can download and run Odoo 20, 19, 18, or any earlier version at no cost. However, you receive no official support: no security patches, no SLA, no bug-fix priority. If you find a security vulnerability, Odoo does not guarantee a patch. Community users typically hire third-party support vendors or deploy internal teams to manage patches and updates.

Enterprise Edition costs money (pricing varies by country and modules used) and includes three years of standard support. Odoo provides security patches, bug fixes, and the ability to escalate issues to support engineers. Enterprise customers also get access to Odoo.sh (the managed SaaS platform), which handles infrastructure, backups, and automated patching.

Enterprise Edition includes all Community modules plus proprietary features like advanced reporting, email integration, and calendar sync. If you are using Odoo for a mission-critical business process, Enterprise Edition is strongly recommended.

For smaller deployments or evaluation, Community Edition allows you to run Odoo 20 for free and test it against your workload. Many companies start on Community and migrate to Enterprise as usage scales.

Should You Upgrade? EOL & Implications

If you are running Odoo 17 or earlier, you have three reasons to upgrade soon.

First, security risk. Odoo 17 support ended in September 2026 (planned). Once that date passes, no more security patches are released. Any vulnerability discovered after EOL affects your instance without a fix from Odoo. You must either patch yourself or accept the risk.

Second, cost. If you are on Enterprise and run Odoo 17 or earlier after Odoo 20 is current (meaning Odoo 16 is more than three releases old), you pay the 25% legacy surcharge. This is a direct financial penalty for delaying migration.

Third, feature drift. New Odoo versions introduce features, integrate third-party APIs, and improve performance. Staying multiple versions behind means you miss accounting regulation updates, payment processor integrations, and modern UX improvements.

The upgrade path is flexible. You can jump from Odoo 17 directly to Odoo 20 without upgrading to 18 or 19 first. However, Odoo recommends testing on an intermediate version first if you have heavy custom code: jump from 17 to 19 in staging, verify your modules work, then jump to 20 in production.

Upgrade windows typically take 4-12 weeks depending on the number of custom modules and the size of your database. Plan for this: do not upgrade on a Friday before a holiday.

How to Upgrade to the Latest Odoo Version

The upgrade process differs between Odoo.sh and self-hosted deployments.

On Odoo.sh, upgrades are managed by Odoo. You log into your Odoo.sh account, select your instance, and request an upgrade. Odoo schedules the upgrade in a maintenance window (usually nights or weekends), creates a backup, performs the upgrade, and tests basic functionality. You are notified when it is complete. The process is typically 2-4 hours.

For self-hosted Odoo, the process is manual. First, set up a staging environment that mirrors your production database and version. Download the new Odoo version source code from Odoo's GitHub repository or from odoo.com. Install the new version alongside your old one (different directories). Run the database migration script that Odoo provides, which updates the schema and data format. Test all critical workflows in staging. If everything works, back up production, repeat the migration on production, and switch over. Then restart the web server.

Custom modules must be ported to the new version. Odoo modules are version-specific: a module written for Odoo 17 may not work in Odoo 20 without code changes. The manifest file ( __manifest__.py) declares which versions a module supports. Before upgrading, verify that every custom module you use has been updated for the new Odoo version by your development team.

Breaking changes are documented in the release notes for each version. Common changes include renamed fields, removed modules, and database schema changes. The release notes tell you exactly what to expect.

Most deployments take 2-6 weeks of testing and custom code updates. Large deployments with hundreds of custom modules can take 12 weeks or more.

Managed Odoo Hosting: Stay Current Without the Headache

If the upgrade process sounds complex, consider managed hosting. Opsily provides managed Odoo hosting that handles all version upgrades, security patching, and infrastructure management for you.

With Opsily, you select your Odoo version when you deploy. When a new major version is released, Opsily's team coordinates with you to schedule an upgrade in a maintenance window. We test your custom modules, perform the upgrade in staging, validate the migration, and then execute the cutover in production. You do not manage the database migration, server updates, or downtime.

Managed hosting also covers security patching: every Odoo security update is deployed automatically to your instance within hours of release. You never fall behind on security. Backup and disaster recovery are built in, so you can roll back if something goes wrong.

Compare this to self-hosting: you hire a systems administrator or DevOps engineer to manage updates, paying $80k-150k/year in salary. Managed hosting costs a fraction of that and includes compliance and SLA guarantees.

Opsily handles all this as part of the hosting fee. You focus on your business; we handle the infrastructure.

Frequently Asked Questions

What is the current Odoo version in 2026?

Odoo 20 is the current version, released in September 2026. Community and Enterprise editions are both available. Standard support continues until September 2029.

How long does Odoo support a version?

Each Odoo version receives three years of standard support starting from its release date. After three years, support ends and no further security patches are released. Customers on Enterprise who continue running an unsupported version after three years pay a 25% annual legacy surcharge.

Can I skip a major Odoo version during an upgrade?

Yes. You can upgrade directly from Odoo 17 to Odoo 20 without upgrading to 18 or 19 first. However, Odoo recommends testing on an intermediate version if you have significant custom code to ensure module compatibility.

Does Odoo Community Edition receive security updates?

No. Community Edition has no official support contract. Security patches are published to the open-source repository, and Community users can apply them themselves, but Odoo does not guarantee patches or provide support. Enterprise Edition includes three years of security updates and support.

When will Odoo 19 support end?

Odoo 19 was released in October 2025 and will receive support until October 2028. After that date, no further security patches are released.

What happens if I run Odoo after support ends?

Your instance continues to function, but you receive no security patches, bug fixes, or support. If a vulnerability is discovered after EOL, Odoo does not patch it. You must either upgrade to a supported version or maintain patches yourself. Enterprise customers running unsupported versions also incur a 25% annual legacy surcharge.

Can I test an upgrade before committing to it?

Yes, strongly recommended. Create a staging environment that copies your production database and runs the new Odoo version. Perform the full upgrade in staging, test all critical workflows, and validate that custom modules work. Only after successful staging should you upgrade production.

Is Odoo upgrading automatically on Odoo.sh?

Odoo.sh does not automatically upgrade you. You must request an upgrade from your account dashboard, and Odoo schedules it in a maintenance window. Managed platforms like Opsily can coordinate the timing with you to minimize disruption.

The Bottom Line

Odoo 20 is the latest release, and every version has a three-year support window. Running an unsupported version exposes you to security risk and legacy surcharges: decide whether to stay current. The upgrade path is clear, but testing and custom code porting require planning: do not underestimate the work. If upgrade complexity is a concern, managed Odoo hosting handles all version migrations, security patching, and infrastructure management for you, so you can focus on your business instead of managing infrastructure.
