* NAMES and WALLOPS command * -cloak option * -v renamed to -verbose * -passwords renamed to -passwd * -debug option prints traffic messages * without -verbose only startup/shutdown and error messages are printed * -timestamped option provides timestamps in printed messages, as earlier. No timestamps is useful for running under daemontools * passwords are stored in SHA256-hashed format * state files replaced with state directory with files * removed many unnecessary pointers and locks * graceful shutdown with all clients notification * fixed time structure printing in log files, instead of short human readable timestamp * PART is sent to the user itself, to notify his client about leaving * log messages are printed to stdout, instead of stderr, for friendliness with daemontools logger * ability to configure newly created directories and files with -perm-state-dir, -perm-state-file, -perm-log-file
