Guides > How versions work

In Slipstream, you can access past versions of Flow Designs and Forms at any time. If you’re in a Flow Design, in the top right corner, click on Edit Flow -> Settings -> and scroll all the way down to find it. In a Form, click on Form Settings -> and scroll all the way down. You should see a box titled “Versions”, pictured in the screenshot above.

Slipstream is designed so you can edit your Flow Designs and Forms freely, making as many changes as you want until it’s published. Once it’s published, changes are rolled out gradually, meaning existing Flows will always use the version that they started with. This means that by default, changes to processes will be non-disruptive, so that process changes will have less impact on the customer experience, while still letting you move quickly.

For Flow Designs, you can add a new version by clicking Publish. Publishing will let Flows using that design to be able to run, unless you’ve configured it differently. You can always unpublish Flow Designs that you don’t want people to be able to start, if you need to pause things for a while.

If you need to make a disruptive change with Flow Designs and move all currently-running Flows to a new version, you can do this manually. First, check in the Flow Design list of versions, and scroll to the right in the table to see the last column. This will list the number of running Flows using each particular version, so you can see how many Flows you might need to cancel. Then you can visit the Flow Results to view all the Flows for a specific version, or search the name of the Flow Design in the detailed My Flows view if you’re unable to view the Flow Results. Administrator privileges are helpful here to make sure there’s no Flows that you might be missing.

Updating a Form has more steps, since Forms are embedded within Flow Design steps. When you publish a new version of a Form, all Flow Designs that use that form will be updated in the editing copy, but they will need to be published if you would like new Flows to use the new version of the Form. Most likely, you will only need to use Forms if you already have formal documents in your organization, since most of the forms that are created in the Flow Designer can be edited and updated just in the Flow Designer.

With all this in mind, you should now know all the intricacies of how versioning works in Slipstream!
