There are about 28 Medinan suras (see here at [[Chronological Order of the Qur'an]]). Sura 60 is
number 5 in the Medinan chronology. So basically there are 23 full suras and partial sura 60 with some or the other contents which abrogates 60:8. You can see the list of abrogator verses here at [[List of Abrogations in the Qur'an]] on the right side. Historic Islamic scholars have however gone down to very intricate details. They specifically stated which verse abrogates which verse. We need not do that. Verses such as 9:5 and 9:29 were revealed a lot of time after verse 60:8. They contradict it with respect to the instruction from Allah.
If somebody gives you one instruction today and its opposite instruction tomorrow, common sense say that you should obey his last instruction. So there is no doubt that Muslims would prioritize violent verses over peaceful ones like 60:8.
