About this guide

This guide explains the main new features and changes in Odoo 20 in simple language for business users, consultants, administrators, and developers.

Examples of AI instructions

"Show me all quotations from ABC Ltd that are still waiting for approval." Or: "Create a follow-up activity for these customers." Odoo can use these instructions to work with business records while following the user's permissions.

AI features in Odoo 20 include:

  • check_circle AI Content Creation: Odoo can help create product descriptions, product titles, marketing content, and SEO content. This can reduce the amount of time employees spend writing repetitive content.

2. Odoo 20 Offline Mode

One of the useful new features in Odoo 20 is offline mode. This can be helpful for employees who work in places where the internet connection is not always available — for example field service workers, warehouse employees, and sales teams. Users can continue working and then sync their changes when the internet connection returns.

01

What You Can Do Offline

Depending on the Odoo app, users can view, search, create, edit, archive, unarchive, and delete records without an internet connection.

02

Changes Sync Later

When the internet connection returns, Odoo can sync the changes that were made offline.

03

Conflict Handling

If two people change the same record while offline, Odoo 20 includes tools to identify and review the conflict so changes are not silently overwritten.

TECHNICAL CHANGES

6. Odoo 20 Technical Changes and JSON-2 API

Odoo 20 includes some important technical changes. These changes are especially important for businesses with custom Odoo modules or integrations.

code

Python 3.12

Odoo 20 requires Python 3.12. Businesses should check their custom modules, servers, Docker setup, deployment scripts, third-party libraries, and development environment before upgrading.

database

PostgreSQL 15

Odoo 20 also requires PostgreSQL 15. Your database and server setup should be checked before the upgrade. Some Odoo features and APIs have changed or been removed — custom modules should be reviewed.

api

JSON-2 API

Odoo 20 moves toward the new JSON-2 API. Older XML-RPC and JSON-RPC APIs are being phased out. Integrations with Shopify, mobile apps, payment systems, shipping systems, BI tools, and other software may need to be updated.

FOR DEVELOPERS & INTEGRATORS

What Should Businesses Do About JSON-2?

Before upgrading, make a list of every system connected to Odoo. Then check which API it uses, how it connects to Odoo, whether it needs to move to JSON-2, whether permissions still work, and whether data is transferred correctly. This should be tested before the new Odoo version goes live.

01

List Connected Systems

Include Shopify, mobile apps, payment systems, shipping systems, BI tools, custom software, and any other external applications.

02

Check the API Used

See whether each connection uses XML-RPC, JSON-RPC, or another method, and plan the move to JSON-2 where needed.

03

Test Before Go-Live

Confirm permissions still work and data is transferred correctly after the API changes.

ODOO 20 // JSON-2 CHECKLIST
01 List integrations All systems linked to Odoo
02 Check API type XML-RPC / JSON-RPC / other
