All Internet Archive releases can be found through their logs for the stackexchange item (login required), but it may take some digging. The list above omits some releases which had errors and were immediately replaced.

    Shameless plug: if anybody is curious, I have recently written a Stack Overflow answer explaining how BitTorrent magnet links work. – Jeremy Mar 11 '14 at 15:26

    I need a StackOverflow Data Dump in which MD5 e-mail checksum are visible. Can you confirm that a kind of this is still availble? Thanks :) – gios91 Mar 30 '15 at 9:18

    @gios91 Unfortunately for that use case, the email hashes haven't been included since either the January 2014 or March 2013 dump (I'm not sure which). As this change was made to increase privacy, it's unlikely to ever be changed back. If you have an academic use intended for it, and affiliations with an academic institution, I think Stack Exchange might provide more complete dumps under an NDA, but I don't remember where I read that, so I can't confirm right now. – Jeremy Apr 1 '15 at 15:52
  • It looks like there Internet Archive's public log files include the infohashes of all generated torrents. You can see one here. So that should allow this list to be maintained even if some updates are missed at the time. – Jeremy Feb 1 '17 at 17:01

    Do we know if the new dump is complete? – Nemo Jan 18 at 13:14
  • @Nemo please define "complete"? What are you missing? – rene Mar 28 at 9:22

    @rene That's my question: "what are we missing?" We don't know until someone tests. A more recent update is at meta.stackexchange.com/a/342634/248268 – Nemo Mar 29 at 8:20

The older dumps from 2009 to 2011 are available here:
