# Understand versioning

eWizard allows for monitoring the number and scale of changes in your items with common versioning rules.

Let's have a look at this process on the basis of the e-Detailer.

# Initial version

Generally, the eWizard item version comprises three digits.

The counting starts from the 0.0.1 version for the newly created items:

# Patching

Once the item is modified in Editor, its last digit increases by one:

No matter, who edits the item–its Creator or any other collaborator–its last digit increases once the Save button is clicked.

# Minor updates

When a new item version is uploaded from the device, its middle digit increases:

The minor update resets patching upgrades to null. Any further item editing results in patching.

# Major updates

At this point, major digit updates are not applicable.

# Versioning history

You can view the item versioning history on the VERSIONS tab of its Details page:

Here you can also roll the item back to any version needed. For this, unfold the required version's more options and click Promote. The promoted version becomes current:
