## Version Numbering and Updates

VergeOS uses semantic versioning with two different formats:

* **Legacy Format**: Major.Minor.Patch.Hotfix (e.g., 4.13.4.2)
* **New Format** (26.0+): Year.Quarter.Minor.Patch (e.g., 26.0.1)
  * First two digits represent the year (25 = 2025, 26 = 2026)
  * Third digit represents the quarter development started (0-3)
  * Remaining digits represent minor and patch versions

{% hint style="success" %}
**Update Process**

* **Minor**, **Patch**, and **Hotfix** updates support live system updates with no impact to running workloads
* **Major** version updates *may* require a system reboot to complete the update process
* Updates should always be performed sequentially within a major version (e.g., 4.13.2 → 4.13.3 → 4.13.4)
* When upgrading from 4.13.x to 26.0.x, follow the upgrade path through 4.13.4.2 first
