The Timeline is your project’s change history. It records every version of the project as a change you can inspect, compare, and restore — so you always know how the logic reached its current state, and you can go back if you need to.

​
Where to find the Timeline

Open the Timeline tab in the right sidebar of the Blueprint Editor. It sits alongside Tests, Agent, Prod Runs, and Comments. The Timeline panel showing a multi-lane change graph with branch pills, apply entries, and struck-through closed drafts Each row is one change, newest at the top. The panel shows:
The collapsed list does not show who made each change. To see the author, open the change card.

​
Streams and the change graph

A stream is a line of changes. Every project has a main stream, and — depending on your change workflow — you can also create drafts, which are separate streams that fork from main and merge back when saved. The graph makes this visible:
  • Fork baseline marks where a draft branched off main.
  • Apply <draft> marks where a draft’s changes were merged back into main.
  • Closed streams are struck through — once a draft has been applied, its history stays visible but is crossed out.
Each stream has its own color, so you can follow a draft from where it forked to where it merged.

​
Open a change to see the detail

Click any change to expand its card. An expanded change card showing the author, timestamp, project version, and the View conversation, Open this version, and Restore this version actions The card shows:
  • What happened — a description and status badges (for example Applied to main), the origin of the change, and the stream it belongs to
  • Who and when — the author, the exact timestamp, and the project version the change produced
  • Actions — inspect, restore, or compare the change
Timestamps in the collapsed list are rounded (3h ago). The exact time — down to the minute — is only shown in the expanded card. Two people working minutes apart can look like a single moment until you open the cards.

Actions on a change

​
Compare changes

Use the Compare section of a change card to see exactly what a change altered:
  • Compare with previous — diff this change against the one before it
  • Select for compare… — pick this change as one side of a comparison, then choose another change (or another stream) as the other side

​
Restore an earlier version

If a change introduced a problem, you can roll the project back:
  1. Open the change you want to return to.
  2. Click Restore this version.
Restoring brings the project back to how it looked at that change. Leapter records the restore as a new entry at the top of the Timeline, so the history in between is never lost — you can always move forward again.

What to do next

  • Change Workflow — choose how edits are saved, and turn on drafts for safer changes
  • Review & Approvals — require review before changes reach main
  • Lab Agent — the conversations behind your changes, available from View conversation
