Odoo 18

Release Notes

EGL Build 260911.1

11 September 2026

NEW Containerized build: Odoo now runs in Docker on AlmaLinux 10. The application and its database are containers, so an application update no longer means replacing the instance.

NEW Odoo 18 Community on Python 3.12 and PostgreSQL 16.

NEW Free SSL and your own domain in one command. Run egl-setup-domain.sh.x and a Let’s Encrypt certificate is obtained and renewed automatically. The tool also locks the address Odoo records for itself, so it cannot revert.

NEW Your Odoo is ready when the instance finishes starting. The database and your administrator account are created for you, so there is no database creation screen and no master password to choose.

FIXED Chat, live notifications and other real-time features now work. The previous build routed them to an address Odoo stopped using at version 16, so nothing reached the service behind it.

FIXED PDF reports print with correct headers, footers and page numbering.

IMPROVED The database is no longer reachable from the internet. It runs on a private network inside the instance, and ports 5432, 8069 and 9090 no longer need to be open. The recommended inbound ports are now only 22, 80 and 443.

IMPROVED Attachments and documents are stored separately from the application, so they are untouched when the application is updated.

IMPROVED The exact Odoo version is fixed in the image and recorded in it. Previously each instance downloaded whatever was current on the day it was launched, so no two were alike.

IMPROVED Installation no longer depends on a single download source. If one is unavailable the installer falls back to others automatically.

IMPROVED AlmaLinux 10 with current patches, replacing AlmaLinux 9.
