🔹 1. Difference between 19.0 and saas-19.x

• 19.0 branch

  • This is the stable community release version
  • Used for on-premise installations
  • Gets bug fixes and minor updates, but no frequent feature changes

• saas-19.2 (or similar saas branches)

  • These are Odoo Online (SaaS) versions

  • Continuously updated with:

    • New features
    • Improvements
    • Fixes before they reach stable releases
  • Used internally by Odoo for their cloud platform (odoo.com)

👉 In simple terms:

• 19.0 = stable public release
• saas-19.x = evolving cloud version (ahead of stable)

🔹 2. Why SaaS branches exist?

Odoo runs its own platform (odoo.com), where:

• Users always get the latest features
• Updates are pushed continuously

So Odoo maintains SaaS branches to:

• Develop and test new features
• Roll them out gradually
• Later merge into future versions (like 20.0)

🔹 3. Is Odoo Enterprise code available publicly?

👉 No, not fully

• The repository on GitHub (odoo/odoo) contains:

  • ✅ Community Edition only (open source)

• Enterprise modules are:

  • ❌ Not publicly available

  • Accessible only if:

    • You have an Enterprise license
    • You link your GitHub account with Odoo

Then you get access to:

• Private repo: odoo/enterprise

🔹 4. What code is in the public Odoo repo?

👉 Everything in:

• odoo/odoo = Community Edition only

Includes:

• Core framework (ORM, views, security)
• Basic apps (sales, inventory, accounting basics, etc.)

✅ Summary

• 19.0 → stable community version
• saas-19.x → continuously updated cloud version
• Public repo → Community only
• Enterprise → private repo (license required)

If you're developing custom modules, it's always safer to build against 19.0, unless you're specifically targeting Odoo Online behavior 👍
