What changed in the Odoo 15 payment module?

The payment module was completely rewritten in v15. The payment.acquirer model was replaced with a new provider architecture, new providers were added (Mollie, Ogone), and old ones removed. Custom payment integrations need rewriting.

Is Odoo 15 still supported?

Odoo 15 is likely past end-of-life by 2026. It was released in October 2021, and Odoo typically provides 3 years of support. Organizations on v15 should plan migration to v18 or v19.

How many new addons did Odoo 15 add?

Odoo 15 added 39 net new addons compared to v14, going from 380 to 419 community addons. Major additions include gift card modules, event booth modules, project bridge modules, and GS1 barcode support.

Can I skip from Odoo 15 to 19?

Yes, using Odoo's migration service or OpenUpgrade. However, you will need to address all breaking changes from v16 (loyalty engine), v17 (attrs removal), v18 (tree-to-list rename), and v19 (module renames) in your custom modules.

What's New in Odoo 15: Complete Feature Guide

Overview

Odoo 15, released October 2021, introduced 419 community addons (up from 380 in v14) with 39 net new addons. The biggest change was the complete rewrite of the payment module (v2.0) and the introduction of gift card functionality across Sales, POS, and eCommerce.

Payment Module Rewrite

The payment module was completely rewritten in Odoo 15. Key changes:

New payment provider architecture replacing the old payment.acquirer model
New providers: payment_mollie, payment_ogone (replaces payment_ingenico)
Removed providers: payment_odoo_by_adyen, payment_adyen_paybylink
Standardized transaction flow and webhook handling

This was a significant breaking change for any custom payment integrations built on the old architecture.

pos_gift_card — sell and redeem gift cards at POS

event_booth — booth categories and management

website_event_booth — online booth booking

Project Enhancements

Multiple new bridge modules connect projects to other business areas:

project_account — project-accounting bridge
project_purchase — project-based purchasing
project_hr_expense — expense tracking per project
project_mrp — manufacturing projects
project_mail_plugin — email integration

Other New Modules

Migration from v14

The payment module rewrite is the most impactful change. Any custom payment acquirers need complete rewriting for the new architecture. Gift card and coupon modules should be reviewed for the new structure. Project bridge modules may overlap with custom project-accounting integrations.
