  • Proposer timeouts are recorded back to Komodo and there's a CLI command to retrieve them
  • Doc for install and elasticsearch log by TonyL
  • Round members are now part of round seed
  • UTXOs from Komodo have an internal lock so they aren't allocated twice
  • Add type identifiers to the step datagrams, so that light clients can know what they are looking at
  • Combined inventory broadcast message (request, index, data) so the algorithm can be tweaked without protocol change
  • Ignore SIGPIPE signal which is sometimes dispatched by the OS
  • Close sockets when done with inbound connections
  • Remove a thread from broadcast
  • KMD UTXO size is 9850 to not conflict with other programs consuming UTXOs
