Sorry, I thought you were the one managing this project 
At first glance, it takes the latest available version (latest).
If you have watchtower installed on your Docker, it will update z2m every day if an update is available.
Yep, for now there’s no Watchtower on Unraid, that’s why I was asking. Does it at another time handle updating an existing Docker, for example at Gladys startup or when I enable/disable Zigbee2Mqtt in the integration?
You’re going to have to stop Gladys and delete your z2m container, restart Gladys.
But I can’t guarantee that the devices will be associated correctly. Maybe you’ll have to re-add them by hand.
1 in 2 chance.
@jgcb00 I really wouldn’t advise you to do that ^^ Indeed, Watchtower is the best for that — don’t you have the option to run a Watchtower manually in Unraid? On the command line?
No updates are managed by Gladys. We use WatchTower to manage Docker updates.
On Unraid you have the CA Auto Update plugin that lets you configure automatic updates.

I’ll try running a watchtower if @guim31’s solution doesn’t work. But I don’t think it will be able to update a Docker container that can’t update even when I force an update!
