Odoo’s versioning framework is engineered to streamline lifecycle governance across apps. The format 19.0.1.0.0 isn’t arbitrary; it’s a structured release taxonomy that drives compatibility, maintenance cadence, and deployment clarity.
1. Major Odoo Version: 19
This number shows that the module is designed specifically for Odoo 19.
It confirms the module has been built, tested, and optimized for Odoo 19’s framework, including its ORM, controllers, security rules, and UI behavior.
Operational meaning:
- Ensures the module works correctly with Odoo 19’s backend, frontend, and database structure.
- Prevents installation on older or newer Odoo versions.
- Supports smooth upgrades because the major version must match the platform version.
This digit essentially guarantees that the module belongs to the Odoo 19 environment.
2. API Stability Indicator: 0
This value shows whether any breaking technical changes have been introduced compared to previous versions.
What it means:
- A 0 indicates no breaking changes. Existing integrations, overrides, and API calls will continue to work.
- If this number increases, it means the module changed in ways that could affect other modules.
- It helps developers evaluate the risk before updating the module in production environments.
This protects teams from unexpected failures caused by API changes.
3. Feature Release Iteration: 1
This number tracks functional improvements to the module.
Interpretation:
- A 1 means this is the first update that includes new features or enhancements.
- Any increase indicates new capabilities, workflow improvements, or UI updates.
- It helps stakeholders distinguish between feature updates and routine fixes.
This value highlights how the module is progressing in terms of functionality.
4. Bugfix Release Index: 0
This number tells how many bugfix updates have been released.
Meaning:
- A 0 means no bugs have been fixed yet after the release.
- When issues such as errors, regressions, or performance problems are resolved, this value increases.
- It helps QA and deployment teams understand the module’s stability.
This digit serves as a quality indicator for post-release maintenance.
5. Technical Revision Marker: 0
This part represents internal improvements that do not affect functionality.
Examples include:
- Code cleanup or refactoring
- Better performance without changing behavior
- Documentation updates
- Security tightening
- Minor internal structure adjustments
This number tracks engineering maintenance to keep the module clean and reliable.
The module version 19.0.1.0.0 provides a structured overview of its compatibility and evolution. The first part confirms the module is built for Odoo 19, ensuring alignment with its core framework. The second part indicates API stability, with a value of 0 showing no breaking changes. The third component reflects functional growth, marking the first feature update. The fourth part tracks maintenance quality, with 0 indicating no bugfixes released yet. The final segment represents internal technical revisions, also at 0, meaning no non-functional adjustments have been made. Together, these elements offer a clear and predictable framework for assessing update impact, managing deployments, and maintaining consistency within the Odoo 19 ecosystem.
