+description: "Learn how flow versioning works in Activepieces"
+---
+
+Activepieces keeps track of all published flows and their versions. Here’s how it works:
+
+1. You can edit a flow as many times as you want in **draft** mode.
+2. Once you're done with your changes, you can publish it.
+3. The published flow will be **immutable** and cannot be edited.
+4. If you try to edit a published flow, Activepieces will create a new **draft** if there is none and copy the **published** version to the new version.
+
+This means you can always go back to a previous version and edit the flow in draft mode without affecting the published version.

+
+As you can see in the following screenshot, the yellow dot refers to DRAFT and the green dot refers to PUBLISHED.
