A new stable re6st version (0.573) is out for all distributions. It features important changes in the re6st inter-node protocol, making it more flexible:
All machines running re6st need to have the re6st-node package upgraded to 0.573 or higher before December 1st 2021.
Starting from this date, machines running older versions will be kicked out of the network.
Once upgraded, please run re6stnet --version to ensure you are running 0.573+
