yes, i meant x86

Actually, most devices today run an amd64 kernel (amd or intel cpus in typical desktops or servers) or arm (phones, some modern notebooks). Those architectures never supported 486 cpus.

I assume, the code removed is in the x86 branch, excluded when compiling for other architectures. As others said, I guess this is mostly about maintainance effort and testing.

(But then i don’t know much about the kernels. Maybe there’s some interplay between amd64 and x64 x86 architectures.)

It’s this or Google or Microsoft if you want something PowerPoint-like.

Many recommend to ‘pick a javascript framework’, which just like LaTeX Beamer sounds good if you do your own thing, but not ideal if people expect PowerPoint. Building slides through code is fundamentally different from drag-on-dropping images.

Pick Google or Microsoft or OnlyOffice and use their web version. This keeps your laptop free of non-free software while using the same tools everyone else has.
