As i said: none of them contains those old SDF nodes. They have new one SDF which are complitely different thing. FTP with old builds no longer contains any alpha versions at all.
Sup folks. Unfortunately it looks like newest Alpha builds (which previously was contain SDF nodes such as "Mesh To SDF Volume") are no longer exist on official site. At try a several of them and even with enabling experimental features and new voluem nodes - SDF nodes are not there :( Maybe some one still have an zip…
