Syscalls added and removed in each Linux release
Most releases don't touch the syscall table at all. When one does, the new syscall usually lands on every architecture at once, often with the same number. Each release with changes has its own page.

A syscall only counts as added when its architecture was already scanned in the release before. When a table starts in a release, everything in it was already there, so none of it shows up as new.
