I have let my colleagues know that the website seemingly didn't update - I couldn't find a error in backend myself, it should have updated correctly. You can use this link to download the server in the meanwhile if you are not using SteamCMD (as we generally recommend): https://eco-releases-staging-eu.s3.eu-central-1.amazonaws.com/EcoServerPC_v0.10.2.2-beta-release-660.zip
If you need the linux server, replace the "PC" with "Linux" in the link.
And should be available on website now as well :)
