v1.06

1.06 2025-07-10

• Options -n and -N for multiple and repeated connections can be
  combined now.
• When using repeated connections, traffic is blocked until
  the connection to the first address is accepted.
• Option -I allows to use iperf3 for TCP tests. The additional
  control connection is spliced bidirectionally.
• Timeout defaults to 10 seconds. It is restarted when all
  connections have been accepted.

v1.05

1.05 2024-08-11

• If TCP splicing ends due to global timeout, exit with error
  status. TCP connections should be shutdown by client side, and
  not aborted by socket splicing relay.
• Print bit per second in statistics with %e to get consistent
  output and proper alignment.

v1.04

1.04 2024-05-13

• Use pkgconf to build on GNU/Linux.
• If splicing of datagram sockets fails with ENOBUFS error, splice
  the sockets again when writing is possible.

v1.03

1.03 2024-01-27

• When runing into timeout, unsplice the sockets.
• Improve printing status line and explain it in man page.
• Better error handling after timeout.

v1.02

1.02 2023-07-04

• Repeat count is limited to 256.
• Option -n multi accepts multiple TCP connections at one listen
  socket.
• Option -N repeat creates multiple listen sockets on consecutive
  addresses and connects to consecutive destinations.
• Option -i idle sets timeout via command line.

v1.01

1.01 2023-06-05

• Create gpg signature .asc for released .tar.gz files.
• Parameter -b bufsize sets send and recv buffer size.

• Timeout parameter is a global limit with default 5 seconds.
• Print format of sockname and peername changed.
• Allow DNS names for addresses and service names for ports.
• Print a status line after splice or copy has finished.
• Run splicebench with pledge "stdio dns inet proc".

v1.00

1.00 2023-06-02

• Convert the splice or copy parameter into a copy switch.
  This results in an incompatible command line syntax.
• Implement UDP splice and copy mode.
