• A --server-bitrate-limit flag has been added as a server-side command-line argument. It allows a server to enforce a maximum throughput rate; client connections that specify a higher bitrate or exceed this bitrate during a test will be terminated. The bitrate is expressed in bits per second, with an optional trailing slash and integer count that specifies an averaging interval over which to enforce the limit (#999).

• update to 3.6

• A new --extra-data option can be used to fill in a user-defined string field that appears in JSON output.

• -B now works properly with SCTP tests.
• A compile fix for Solaris 10 was added.
• Some minor bug fixes for JSON output. In particular, warnings for debug and/or verbose modes with --json output and a fix for JSON output on CentOS 6
