# Updating to new version

The application automatically checks for new versions to ensure that users are working with the latest available version. Depending on the update type, the user may either install the update immediately or postpone it until later.

**Optional update**

If a new version of the application is available and the update is not mandatory, the user will see the following button <img src="/files/F9yicDByxj3LzmKBMnSj" alt="" data-size="line"> in the header of the app.&#x20;

By clicking it the following window will appear:

* Update - the page will be reloaded and the new version of the application applied;
* Later - closes the window and allows the user to continue working with the current version unless a mandatory update is required.

**Mandatory update**

If the application version becomes outdated and requires an immediate update, a mandatory update window will be displayed automatically:
