Doesnt see them in the https://builder.blender.org/download/daily/archive/
Click “all archived builds” on that page.
All Alpha there starts from 4.1.x
Not every alpha version is archived… only fo the actual one… it is just to much data…
Also the have too much bugs… actual version id for comparison. For older version there are only the releases…
Also older test-branches aren’t archived… big data → big costs…
…oh and some release candidates…
Yeah, keeping every alpha build of every day that one is created requires a massive amount of storage space. Also, I can’t really figure out why someone would want a random alpha version from September 14th, 2022…
