| # 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. |
|

|
| ## 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 |
|
|
| ```python |
| 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. |
