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.

Browse the same data, with Enterprise coverage and upgrade notes, in the free Odoo Change Explorer.

Files

Config	Rows	One row per
`changes`	8,662	model or field added, removed or renamed in one upgrade step
`fields`	18,984	field of a model, with the versions it exists in
`models`	1,230	model, with the versions it exists in

`changes`

Column	Meaning
`step`	Upgrade step, such as `19->20`
`change`	`model_added`, `model_removed`, `model_renamed`, `field_added` or `field_removed`
`model`	Technical model name, such as `res.partner`
`field`	Field name, for field changes
`field_type`	Field type, such as `Many2one`, for field changes
`module_or_new_name`	The module that defines it, or the new model name for `model_renamed`

`fields`

model, field, type, relation (the related model for relational fields), label, module, then in_odoo_16 to in_odoo_20 as true or false.

`models`

model, description, module, then in_odoo_16 to in_odoo_20 as true or false.

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.
