# Version History

> See what changed on an assistant, and put any single setting back.

Every save that changes something is kept as a version, so you can see what moved and undo one
setting without losing the rest of your work.

## Opening it

Click **History** in the assistant header. **Review** in the save bar opens the same panel, on your
unsaved changes.

## What you see

At the top sits **Draft — unsaved changes**: what you have edited but not saved yet. Under it,
**Version 1**, **Version 2** and so on, newest first, each showing the settings that changed in that
save and what they were before. **Show older versions** loads the rest.

## Reverting

Each line has its own **Revert**. Reverting puts that one value back into your draft — it does not
touch anything else, and it does not save by itself. Look at the change, then press **Save
assistant** to keep it.

<Note>
  Because a revert lands in the draft, you can revert several lines, look at them together in the save
  bar, and save once.
</Note>

## What is kept

The last 50 versions of each assistant. Older ones drop off as new ones are recorded.

## What it does not cover

History records settings. It does not roll back calls that already happened, and it does not restore
a deleted assistant.
