Odoo 20 is the latest major version of Odoo. Odoo's official release notes date it September 2026. The previous major version, Odoo 19, was released in September 2025. Odoo states that it supports each major version for three years. On 25 September 2026, its support table listed standard support for 17.0 ending in September 2026, 18.0 in September 2027 and 19.0 in September 2028 (all marked "planned"). The table had not yet added a row for 20.0.
That paragraph answers the search query. The rest of this guide covers what most teams need next: how long each version is supported, how Community and Enterprise versioning differ, whether to upgrade now or wait, and what the upgrade path looks like. We implement and migrate Odoo commercially, so the version question comes up with our clients every week. Sources are Odoo's Odoo 20 release notes and its standard and extended support page, both read on 25 September 2026.

Odoo version history
Odoo renamed itself from OpenERP in 2014 and has shipped a major version roughly once a year since. Dates below are from Odoo's support table (read 25 September 2026) and, for 20.0, from its release notes.
| Version | Release date | Standard support (per Odoo) | Notable for |
|---|---|---|---|
| Odoo 14 and older | Before 2021 | Ended before 2024 | — |
| Odoo 15 | October 2021 | Ended October 2024 | New website builder, faster JS framework groundwork |
| Odoo 16 | October 2022 | Ended September 2025 | Owl 2 frontend framework, big accounting overhaul, major speed gains |
| Odoo 17 | November 2023 | September 2026 (planned) | New look and feel, redesigned Discuss, keyboard-first UX |
| Odoo 18 | October 2024 | September 2027 (planned) | AI features, faster reporting engine, POS and inventory improvements |
| Odoo 19 | September 2025 | September 2028 (planned) | Deeper AI integration across apps, new Studio capabilities, performance and UX refinements |
| Odoo 20 | September 2026 | Not yet listed in Odoo's table (three years per Odoo's policy) | AI agents that create and update records and connect over MCP, offline mode, simplified access rights, parent accounts |
Between major versions, Odoo also releases intermediate "SaaS" versions (19.1 to 19.4 in 2026) every two to three months. They exist only on Odoo Online and are not eligible for extended support.
For the feature-by-feature breakdown, see what's new in Odoo 20; for the previous release, see our guide to Odoo 19.
How long does Odoo support each version?
Odoo's policy, in its own words: "Odoo provides standard support for all major versions for three years. It includes helpdesk support, bug fixing, and security updates. Beyond those three years, extended support is subject to a mandatory additional fee and includes helpdesk support and bug fixes (depending on feasibility)."
As of 25 September 2026, that means:
- Odoo 20: just released. The best choice for a new implementation once the modules you need exist for it.
- Odoo 19: standard support listed until September 2028 (planned). Fully fine to run.
- Odoo 18: standard support listed until September 2027 (planned). Plan an upgrade window in the next year.
- Odoo 17: standard support listed as ending September 2026 (planned). After that, only paid extended support. Upgrade planning should already be under way.
- Odoo 16 and earlier: past standard support. Every month adds security exposure and migration debt.
One detail that surprises teams: per Odoo's documentation, "You can upgrade from any version to supported versions only," and the last unsupported version can still be used as an upgrade target for up to six months after its end-of-life date. A 2-version jump is routine; a 5-version jump is a project.
Community vs Enterprise: same version number, different product
Both editions follow the same version numbering and release on the same day. Odoo 20 Community and Odoo 20 Enterprise share the same core framework and ORM. The differences that matter for the version decision:
| Aspect | Community (free, LGPL) | Enterprise (per-user subscription) |
|---|---|---|
| Version cadence | Same annual major release | Same annual major release |
| Apps included | Core apps (CRM, sales, invoicing, inventory, website, manufacturing basics) | Everything in Community plus accounting full version, payroll, helpdesk, field service, quality, PLM, marketing automation, Studio, and more |
| Official upgrade service | Not included — you migrate yourself or hire a partner | Included — Odoo SA's upgrade platform migrates your database between versions |
| Hosting | Self-hosted only | Odoo Online (SaaS), Odoo.sh (PaaS), or on-premise |
| Mobile apps and AI features | Limited | Full |
The upgrade-service line is the one that bites. Community users who skipped three versions discover that the free edition has no official migration path — community tools like OpenUpgrade exist and work, but they require real technical effort. This is the hidden cost of "free" that should factor into your edition choice. Our Odoo migration service handles both editions, including multi-version Community jumps.
A separate nuance: Odoo Online (the SaaS edition) makes upgrades mandatory on a schedule. Odoo's upgrade documentation says a database on a major version must be upgraded every two years, and Odoo notifies you before it triggers an automatic upgrade. On-premise and Odoo.sh customers control their own timing, which is exactly why the "should I upgrade" question below exists.
Should you upgrade to Odoo 20? Decision matrix
Upgrading is not automatically best practice. A version migration is a project, typically 2 to 8 weeks for an SMB depending on how much is customized and how much data there is. Here is the framework we use with clients:
| Your situation | Recommendation | Why |
|---|---|---|
| New implementation starting now | Start on Odoo 20, unless a module you need has no 20.0 build yet | No migration later and the longest support runway. Check module availability first |
| On Odoo 19, stable, no pain points | Test an upgrade; move when the 20.0 changes pay for it | Support is listed until September 2028 (planned). There is no rush |
| On Odoo 18 | Plan an upgrade within the next year, to 19 or 20 | Standard support is listed until September 2027 (planned) |
| On Odoo 17 | Upgrade now | Standard support is listed as ending September 2026 (planned); after that, support costs extra |
| On Odoo 16 or older | Upgrade urgently | Past standard support. Every custom module and every data-model change between versions adds to the cost |
| Heavily customized instance (20+ custom modules) | Budget a code-migration phase first | Porting custom modules is the dominant cost, not the data migration. Audit module compatibility before committing to a date |
Three rules of thumb from migration projects we have delivered:
- Test before you commit. Odoo's process gives you an upgraded test database first. Use it, especially in the first weeks of a new major version.
- Skipping versions is cheaper than annual upgrades for most SMBs. Migrating 16 to 19 or 20 directly costs far less than several yearly projects.
- Module compatibility is the real gate. Odoo's documentation says a database with custom modules cannot be upgraded until those modules exist for the target version. List your installed modules and confirm each one has a target-version release before you schedule anything.
For the step-by-step process, see our Odoo 19 to 20 upgrade guide.
What does an Odoo upgrade cost in 2026?
Rough ranges from real projects, assuming Enterprise edition with the official upgrade service handling the database:
| Scenario | Typical effort | Typical budget |
|---|---|---|
| Vanilla Odoo, no custom code, 1-version jump | 1–2 weeks | $2,000–$6,000 |
| Light customization (under 10 custom modules), 1–2 version jump | 3–6 weeks | $6,000–$20,000 |
| Heavy customization (20+ modules), 2–3 version jump | 2–4 months | $20,000–$80,000+ |
| Community self-hosted, multi-version, no upgrade service | Highly variable | Add 30–60% to the above |
These are implementation-partner figures; your internal team time is additional. The single biggest cost driver is custom module count, followed by version distance.
How ECOSIRE handles versions in our module marketplace
A practical note for teams that buy third-party modules: version coverage is a real procurement criterion. A module that only exists for an old version anchors your whole instance to it.
Modules in the ECOSIRE Odoo apps marketplace are licensed per major version, and each version is a separate build. Many listings are built to order rather than kept in stock, so a listing does not guarantee that a build exists for your version. Our Odoo 20 compatibility page is generated from our live download records and shows, for every module we publish, which of 17.0, 18.0, 19.0 and 20.0 you can download today.
If one of your upgrade blockers is a third-party module with no build for your target version, that is usually solvable: porting a well-structured module between adjacent versions is a well-understood task. It is one of the most common requests our Odoo migration team handles alongside full instance upgrades.
