# version var (world)

Source: https://ref.dm-lang.org/world/var/version

### Default value
> 0

If you are distributing your game to players, you can use this variable to automatically notify them of new releases. To do so, you will first need to set [`world.hub`](https://ref.dm-lang.org/world/var/hub.md) to the hub path of your game. You can then advertise the current version by configuring that value in your [hub console](httpscolon/slashsecuredotbyonddotcom/members/querycommandequalsedit_hub).

When players boot up an outdated version of your game (as indicated by comparing `world.version` with the version advertised by BYOND hub), they will be notified of the new release.
