yes, latest full build is 25398.287 latest CU version is 25398.408 also there's new "Feature update to Azure Stack HCI, version 23H2, dev build (25398.1) amd64" version - don't use it, it has some uwp apps and it shouldn't
if you want to get old 25398.287 build then enable "fetch_sync_current_only" option and add that "25398.287" build manually You originally asked about 25398.1 build - if you want to get that base build then use your 25398.408 build and disable "Include updates (Windows converter only)" option on the website
@Paul Mercer, You or someone who fetches daily could make a package of the folders: packs fileinfo But only from September 1st to the most recent one there? I'm very grateful.
