ptr1337 [1] filed a deletion request for zen-browser-optimized-bin [2]: There is already "zen-browser-avx2-bin", which exactly comes with the "specific" version, which is compiled with the x86-64-v3 instruction set. Therefore this should be deleted [1] https://aur.archlinux.org/account/ptr1337/ [2] https://aur.archlinux.org/pkgbase/zen-browser-optimized-bin/
