Release of version 0.9.0

Added

• Server fills are now supported, and may be restricted on the server. See
  --sfill for the client and --allow-fills on the server. As an example, one
  can do irtt client --fill=rand --sfill=rand -l 172 server for random
  payloads in both directions. The server default is --allow-fills=rand so
  that arbitrary data cannot be relayed between two hosts. server_fill now
  appears under params in the JSON.
• Version information has been added to the JSON output.

Changed

• Due to adoption of the pflag package, all long
  options now start with -- and must use = with values (e.g. --fill=rand).
  After the subcommand, flags and arguments may now appear in any order.
• irtt client syntax changes:
  • -rs is renamed to --stats
  • -strictparams is removed and is now the default. --loose may be used
    instead to accept and use server restricted parameters, with a warning.
  • -ts is renamed to --tstamp
  • -qq is renamed to -Q
  • -fillall is removed and is now the default. --fill-one may be used as
    a small optimization, but should rarely be needed.
• irtt server syntax changes:
  • -nodscp is renamed to --no-dscp
  • -setsrcip is renamed to --set-src-ip
• The communication protocol has changed, so clients and servers must both be
  updated.
• The handshake now includes a protocol version, which may change independently
  of the release version, and must match exactly between the client and server
  or the client will refuse to connect.
• The default server minimum interval is now 10ms.
• The default client duration has been changed from 1h to 1m.
• Some author info was changed in the commit history, so the rewritten history
  must be fetched in all forks and any changes rebased.
