Basically, what's marked as 2.4.18 is really -rc3, and what's marked as -rc4 is what should have become 2.4.18. According to Marcelo on #kernelnewbies, most users won't be affected, but people on SPARC systems should definitely grab 2.4.18-rc4. Your best bet is probably just to get 2.4.17 and patch to 2.4.18-rc4. Seems 2.4 is destined to be an "interesting" release branch ^_^; For the new release, head over to your favorite kernel.org mirror. (Marcelo will set things straight in 2.4.19-pre1.)"
