# Update a UPM package for the Asset Store

> Publish new versions of existing Asset Store packages with updated content or properties.

You can update a published Editor to release a new version of the package with bug fixes or new features, or to change product details such as pricing and media. When you publish an update, users can access the new version in the [Package Manager window](https://docs.unity3d.com/6000.6/Documentation/Manual/upm-ui.html).

You can make two types of updates, and each has different required information as follows:
