# Mapping fix versions

One of the options Avion provides is the ability to sync Avion releases to fix versions.

{% hint style="info" %}
**Fix versions** or **versions** are also known as **releases** in Jira. Their terminology isn't consistent, so we stick with the term fix versions.
{% endhint %}

In some projects, fix versions might not be enabled. This is a simple fix to enable fix versions. Head to **project settings**:

Then hit **features**:
