Version History

Every time a project is saved — by you pressing Cmd/Ctrl + S or by autosave — de:volt records a revision. On Pro you can browse that timeline and roll back to any earlier point. There is no separate “snapshot” step to remember; the history builds itself as you work.

Opening the timeline

Open the File menu and choose Version history…. The project must have been saved at least once. On Hobby and signed-out accounts the menu item reads Upgrade for version history and links to the upgrade page instead.

Reading the list

Revisions are listed newest first (up to the most recent 100). Each row shows:

• A kind badge — autosave, manual, or milestone.
• An optional label or message.
• The component and wire counts at that point in time.
• When it was saved.

This makes it easy to find the moment before a change went wrong, or the last known-good layout.

Restoring

Press Restore on any earlier revision and confirm. Restoring is non-destructive: it brings that circuit back as a new revision on top of the timeline rather than deleting anything after it. Your current state stays in the history, so you can always restore forward again. The current head revision has no Restore button because it is already what you are editing.

Naming milestones

To mark an important version — “breadboard layout final”, “before adding the 555” — use Name milestone (or Edit milestone) on a revision. This flips the row to the milestone kind and gives it the label you type, so it stands out in the list. Clearing the name turns it back into a normal revision.

Retention

de:volt keeps every revision; nothing is pruned automatically. On Hobby, saves still record revisions in the background, but the timeline, restore, and milestone tools stay locked until you upgrade — so upgrading later gives you access to the history that accumulated while you were on Hobby.
