This question already has an answer here:
I am a YouTuber and I'm thinking of making a modded series with my friend. I went to the Minecraft website to download v1.6.4 of the server, but they don't have it. So I then searched via Google and found McNostalgia and MVC (Minecraft Version Changer) but it only had v1.6.2 and below.
How can I obtain the Minecraft server jar for an older version?
