When I saw the Parallella (https://parallella.org) listed there I thought that it must be a very old list, but it turns out that it’s still being sold at least by Digikey.

The page is updated though, as can be seen in the edit history with the link at the page footer: https://joelw.id.au/FPGA/CheapFPGADevelopmentBoards?action=d...

I’ve sent an e-mail to the author pointing him to this discussion in case other corrections get posted here.
