Version comparison

Odoo versions, v8 through v20

Odoo ships a new major version roughly every year. Here's where each one sits relative to today, and what that means for whether you're paying a legacy surcharge without realizing it.

The short answer

Odoo officially supports its three most recent major versions — v18, v19 and v20 now that v20 is current. Since 2026, Enterprise contracts on older versions (v17 and earlier) carry a 25% legacy surcharge. For almost everyone, the right upgrade target is the current release, v20.

Release years are approximate; Odoo follows a roughly annual cycle. "Supported" reflects Odoo's policy of officially covering only its three most recent major versions — this table shifts forward every year a new version ships, so treat "current" as relative to today, not fixed.

The part most people miss

25%

legacy uplift on Enterprise contracts more than two releases behind

Upgrading now unlocks an easy win on cost

In 2026, Odoo introduced a 25% legacy-version surcharge on Enterprise contracts for versions more than two releases behind current — upgrading removes it. If your version is more than two releases behind in the table above, that saving is available the moment the project completes, on top of everything new you gain along the way.

Target version

Which version should you target?

Almost always: the current release.

Odoo's managed upgrade path and most migration tooling handle a large version jump in a single pass, so there's rarely a cost advantage to landing on an older "safer-feeling" version first — you'd just be scheduling a second upgrade project sooner than necessary. The exception is a genuinely unusual compatibility requirement with a specific third-party integration, which is worth flagging during discovery rather than assuming upfront.
