# Data Asset Versioning | Version Control Guide

# Data Asset Versioning
Collate automatically tracks every change to a data asset's metadata, giving you a complete history of how your data evolved over time.
## Version Types
Versions follow a **major.minor** format, starting at **0.1** when an asset is first created.
* **Minor version** (+0.1) — A backward-compatible change. Triggered when a description, tag, or ownership is added, updated, or removed. For example, version 0.1 → 0.2.
* **Major version** (+1.0) — A backward-incompatible change. Triggered when a column is deleted at the source. For example, version 0.2 → 1.2.
## What You Can Do with Version History
* **Debug data issues** — See exactly when a metadata change was made and whether it caused a problem downstream.
* **Review and govern changes** — Data owners and admins can audit who changed what and when, supporting data governance requirements.
* **Enable collaboration** — When more users contribute metadata, versioning keeps a traceable record of every contribution.
## Accessing Version History
1. Open any data asset and click the **Version** icon in the top-right area of the asset page.
2. The **Version History** panel lists all recorded changes. Select any version to see what changed, including which fields were updated and whether the change was minor or major.
