Half-Life Dedicated Server has not been updated

[SamVanheer]

Half-Life Dedicated Server, app 90 on Steam has not been updated to the new version: https://steamdb.info/app/90/depots/

The depots that aren't shared with other games are out of date and can cause compatibility issues. Users have reported problems trying to host dedicated servers using this app: https://knockout.chat/thread/55507/15#post-2030223

App 90 is required to host servers without having to log in to a Steam account that owns the game. Is this still the method that server operators need to use today?
