envolution [1] filed a request to merge stremio-beta [2] into stremio [3]: There is no beta branch, and this just offers the same version as aur/stremio currently does.
This package has been flagged since April [1] https://aur.archlinux.org/account/envolution/ [2] https://aur.archlinux.org/pkgbase/stremio-beta/ [3] https://aur.archlinux.org/pkgbase/stremio/
