Tried to upgrade my storage node to 1.19.6 but still got 1.18.1

Hello,
Right now I am running the storage node 1.18.1 with Docker and Linux.
I saw, that there is an updated version 1.19.6.

So I tried to use the manual update guide. I removed the old one. Then used the command:

docker pull storjlabs/storagenode:latest

And then restarted my storagenode. But it still shows me 1.18.1.
Is there no new docker image yet for 1.19.6 ?

Thanks for your help.
