Version 1.0.0b1 (beta version)

Changes:

• changed: requires Python 3.5+ now

  possible

  by using the new bestN shortcut
• changed: use external JSON files for configuration, by default try to load .py3createtorrent.cfg
  from user's home directory
• added: DHT bootstrap nodes can now be specified with the new --node switch (doing so is recommended for
  trackerless torrents)

• changed: increased max piece size to 16 MiB
• changed: show warning if piece size is not a multiple of 16 KiB
