Odoo Model and Field Changes, Odoo 16 to 20

Which models and fields were added, removed or renamed between Odoo 16, 17, 18, 19 and 20, for Odoo Community. Built by parsing the Odoo source code of each release.

Use it to plan an upgrade, to check whether a custom module still points at fields that exist, or to give an AI coding assistant accurate facts about a specific Odoo version.

Quick start

from datasets import load_dataset

changes = load_dataset("msubash96/odoo-model-changes", "changes", split="train")
removed = changes.filter(lambda r: r["step"] == "19->20" and r["change"] == "field_removed")
print(removed.select(range(5)).to_pandas())

How it was built

A static parse of the Python models (_name, _inherit, _inherits and fields.* declarations, with mixins merged) of every module in each release. A field counts as removed only when no parent, mixin or delegated model still provides it.

• Sources: Odoo 16.0, 17.0, 18.0, 19.0 and 20.0 Community.
• Scope: models and fields defined by Community modules only. Models and fields that come only from Enterprise modules are left out.
• Generated: 2026-10-14.

Limits

• Field renames are not detected as renames. A renamed field appears as one field_removed and one field_added.
• Changes in field attributes, such as a new required or a changed selection list, are not included.
• Fields added at runtime, outside the Python declarations, are not seen.
