# Spec Versioning

> How we manage changes to the routing logic.

The `spec_version` field in `vectors.json` follows Semantic Versioning (SemVer) rules.

## Versioning Rules

* **Patch (1.0.x)**: Added non-breaking test vectors or updated documentation.
* **Minor (1.x.0)**: Added new features that are backward-compatible (e.g., a new warning code).
* **Major (x.0.0)**: Breaking changes to the routing logic or output schema.

<Info>
  All implementation packages must release the same version number to guarantee cross-language compliance.
