# Version history and rollback

FunctionFlow AI · Test & publish · Updated October 3, 2026

> Every change to a function’s rule is saved as a version. Compare any two versions and restore an older one in one click.

FunctionFlow keeps a version every time a function’s rule changes, so you can see what changed and go back if something goes wrong.

Open it with **History** in the builder header, or **Version history** in a function’s menu on the Functions page.

![Version history with one version marked Latest draft, and View and Restore & publish actions](https://help.fleekapps.com/media/functionflow-ai/versions.webp "Each version shows its note, a summary of the rule, and when and by whom it was saved.")

## What creates a version

A new version is saved when:

- you create a function (v1),
- you save a change to its **conditions or actions**,
- you duplicate or import it, or restore an older version.

Saving with no change to the rule doesn’t create a version, and neither do changes to the title, note, dates, discount settings or test mode. Versions never change once saved.

## Read the list

- **Version** — *v1*, *v2*… The published version is marked **Live**; the newest unpublished version is marked **Latest draft**.
- **Change** — the version note (for example *Rollback to v2*) and a one-line summary of the rule.
- **Saved** — when and by whom.

## Compare two versions

Tick two versions and click **Compare selected**. You’ll see the rule line by line: added lines in green with **+**, removed lines in red with **−**.

## View a version

**View** shows the version’s summary and the exact configuration sent to Shopify.

## Restore an older version

Click **Restore & publish** on the version you want and confirm. FunctionFlow saves it as a **new** version — nothing is deleted — and publishes it to your store right away, keeping the function’s current test mode, dates and discount settings. You can always roll forward again the same way.

> **Note:** Restoring publishes immediately. To look at an old version without publishing, use **View** — or **Compare** it with the current one.
