I want to download the latest valid release of kernel 2.4.
I look at ftp.kernel.org and here the highest release available is 2.4.31, while searching on others mirrors I found that ther is also higest release, until 184.108.40.206 and on some other site they spoke about a 220.127.116.11 release ( ss. linux.softpedia.com/get/System/Operating-Systems/Kernels/Linux-Kernel-2-4-3022.shtml ).
I'm wondering why the official repository didn't list the releases above 2.4.31. Are these release unofficial or not approved or something similar ?
