  Old copies will be left in place.
• The log timestamp format is now ISO 8601 (e.g. "2019-01-28T15:41:17Z")
• Behavior change: in case of multiple values for an argument, the following rules apply:
  • From the command line, the last value takes precedence
  • From the config file, the first value takes precedence
  • From the config file, if an argument is negated it takes precedent over all the
    previous occurences of this argument (e.g. "foo=2 \n nofoo=1" will set foo=0)
• The configuration files now support assigning options to a specific network.
  To do so, sections or prefix can be used:
  main.uacomment=bch-mainnet
  test.uacomment=bch-testnet
  regtest.uacomment=bch-regtest
  [main]
  mempoolsize=300
  [test]
  mempoolsize=200
  [regtest]
  mempoolsize=50
  The addnode=, connect=, port=, bind=, rpcport=, rpcbind=
  and wallet= options will only apply to mainnet when specified in the
  configuration file, unless a network is specified.
