# App versioning

The ComUnity Development Toolkit allows you to set up versioning for your apps(**iOS**, **Android** and **Windows**) using the following convection: 

```
x.y.z

Whereby:
- x,y and z are dot seperated digits and,
- x denotes the major, y denotes the minor and z denotes the build.
```

When you change the major or the minor, your users will receive an in-app notification prompting them to upgrade to the latest version.

{% hint style="info" %}
Whenever you ship a breaking change update your app version by incrementing either the major or the minor so as to prompt your users to upgrade.
{% endhint %}
