    Release Notes: This release adds statistical conditional branching, a 3PCC extended mode, a tool to monitor remote SIP servers through SNMP, a global commandline option to specify that packets should be lost at a given percentage, and many small enhancements, including major performance improvements. clock_tick is updated more frequently now, for higher timer and statistics resolution (in microseconds).

      Release Notes: Performance has been greatly improved by a factor of 10 in some cases. Media play is supported on Windows platforms. Statistical pauses emulate real user behavior. TCP/TLS has been fixed on Windows platforms. The ability to use SIPp as an open loop generator has been added. The ability to automatically increase the call rate at specific intervals (benchmarking) has been added. There are over 75 other bugfixes and improvements.

                Release Notes: Support for the SIP short form, a new [cseq] keyword, a race_rtt command for dumping all response times in a CSV file that can be parsed using "Octave", a max_socket option for sharing opened TCP/TLS sockets, a new "auth_uri" command line parameter, basic support for RFC3262 (PRACK), and -tls_cert and -tls_key options for providing TLS certificate and key files were added. Video RTP echo was added (using -mp port + 2 port) along with a new [branch] keyword. The regexp embedded scenario now has a sub-expression example. Several bugfixes were made.

                  Release Notes: This release adds support for IPv6, TLS, authentication, conditional branching in scenarios, more actions (log, system exec, abort call), automatic Content-Length computation, and sub-expressions in regular expressions. It is available both as source tarball and a Win32 installer.

                    Release Notes: This release changes all trace file names from pid_scenario to scenario_pid. It enables the -trace_err switch. It also fixes quitting 3PCC controller with ctrl-c and allows reuse of internal twin socket just after closing, and now supports regexp with < or >. A really disabling retransmission when -nr switch was specified for UDP transport was fixed. There are some performance improvements in TCP, and a bug where SDP elements were not properly ordered in default scenarios has been fixed.

                      Release Notes: Calls that timeout are logged. The PID is used in the name of the CSV stat file. Screens are dumped to a file when the SIGUSR2 signal is received. The process PID was added to trace files names. A timestamp was added in SIP message traces. The statistics on unexpected messages for an existing call and the statistics on unexpected messages for a non-existing call are now distinguished. Minor bugfixes were made.
