June 4, 2020 Developers release Bitcoin Core 0.20.0 software update.

Bitcoin Core developers have released the latest software update for the Bitcoin Core client. The update, version 0.20.0, was released on Wednesday and makes significant changes to P2P networking among other changes. The update notably introduced a new experimental configuration option, called ‘asmap’ that aims to counter Erebus attacks, a type of theoretical network attack whereby extremely large internet service providers could isolate nodes, allowing them to conduct double-spending and 51% mining attacks.
