Namecoin Core has been released on the Downloads page.

Here’s what’s new since 0.18.0:

  • The mempool now allows multiple updates of a single name (in a chain of transactions). This is something that is allowed in blocks already, i.e. it is just a policy change. The name_update RPC command still prevents such transactions from being created for now, until miners and relaying nodes have updated sufficiently. More details can be found in #322.
  • Numerous improvements from upstream Bitcoin Core.
