# Revisions & History

The Revisions tab gives you a full audit trail of every published Field Mapping configuration for this Connector, and lets you compare any revision against the one that preceded it.

![The Revisions tab for AOH Test AD → CloudSync (Delta), showing the Mapping Revisions section with a message that no revisions have been published yet, and a right panel instructing the user to select a revision to view its diff](/files/jVmMAaZHU4MdItZdIgHo)

*The Revisions tab lists every published mapping revision and shows a side-by-side diff when you select one.*

## What you can do here

| Action                 | What it does                                                                                                           |
| ---------------------- | ---------------------------------------------------------------------------------------------------------------------- |
| View the revision list | See every published version of this Connector's Field Mappings, in chronological order.                                |
| Select a revision      | Loads a diff view in the right panel showing exactly what changed between the selected revision and the one before it. |

## How revisions work

Every time you publish a set of Field Mapping changes, AOH Sync creates a new revision entry. Revisions are immutable — once published, the record of what was active at that point in time is preserved. This lets you:

* **Audit changes** — See who published what and when.
* **Understand impact** — The diff view shows which mappings were added, removed, or modified in each publish.
* **Identify the cause** — The diff view shows which revision introduced a change, helping you diagnose unexpected behavior.

{% hint style="info" %}
The revision list is empty until at least one set of mapping changes has been published. Saving changes on the Mappings tab without publishing does not create a revision.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.aohwv.dev/feature-reference/connectors/revisions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
