v1.4.2

Release Notes

API/ABI Changes

• SRT_MSGCTRL.srctime now expects SRT internal clock timestamp (as returned from srt_time_now()). In previous versions a wallclock time in microseconds since the UNIX epoch was expected.
• Several fields were added to the CBytePerfMon structure (statistics).

New Features and Enhancements

• FR #1103: Added support for C++11. Reworked timing and synchronization objects.
  Three sources of timing are now available (selected via a build option):
  • POSIX gettimeofday() - default build mode (affected by discontinuous jumps in the system time);
  • POSIX CLOCK_MONOTONIC. CMake build option: -DENABLE_MONOTONIC_CLOCK=ON. See --enable-monotonic-clock in BuildOptions.md;
  • C++11 std::chrono::steady_clock, std::thread, std::mutex, etc.​ CMake build option: -DENABLE_STDCXX_SYNC=ON. See --enable-stdcxx-sync in BuildOptions.md.
• PR #1367: Added SRT Source Time API support. It allows setting a source timestamp on a packet that corresponds to a packet creation/reception time. See the Time Access section of the API docs.
• PR #1362: Added an improved retransmission algorithm which reduces the retransmission overhead on a link. Set option SRTO_RETRANSMITALGO=1.
• PR #1203: Added SRTO_BINDTODEVICE option to bind a socket to a specified NIC. SRTO_BINDTODEVICE option reflects the system option SO_BINDTODEVICE for an SRT socket.
• PR #1291: Customizable rejection reason code. SRT library now lets the application provide a code with rejection reason (in a listener callback) if connection request has been rejected by the application. See Rejection Codes in the Access Control guide.
• PR #1194: Added new rejection reason: on timeout. See SRT_REJ_TIMEOUT in API-functions.md.
• PR #1283: Extended SRT statistics with pktSentUniqueTotal, pktRecvUniqueTotal. Statistics documentation now has a summary table for better navigation.
• PR #1024: Added srt_getversion() API function.
• PR #1510: Moved socket options documentation to a separate file APISocketOptions.md. It now has a summary table for better navigation.
• PR #1536: Socket options SRTO_INPUTBW and SRTO_OHEADBW are now readable.
• PR #1440: The logging functionality has been improved by means of defining new and more fine-grained Functional Areas (FA) to which log messages are assigned. This is done to prevent too many debug log messages from the library influencing performance with the debug logging turned on.

Fixed Issues

• PR #1500: Fixed bug: finding the listener's muxer only by port number was wrong.
• PR #1480: Fixed wrong reject reason on async connect.
• PR #1359: Fixed CSndLossList::insert with negative offset.
• PR #1381: Fixed default binding for IPv6-target rendezvous.
• PR #1417: Fixed HS TSBPD flags check.
• PR #1431: Improved CRcvLossList protection from concurrent access.
• PR #1388: Fixed error reporting on connect/accept.
• PR #1355: Correctly handle IPv4 connections on IPv6 listener.
• PR #1348: Fixed Moving Average for receiver and sender buffers. Also PR #1289.
• PR #1335: Protecting RCV buffer access.
• PR #1333: Fixed local storage depleted issue #486.
• PR #1332: Fixed restrictions on pre-bind only options.
• PR #1136: Avoid reporting packets rebuilt by FEC as lost.
• PR #1148: Improved inserting a serial element into sender's loss list.
• PR #1079: Fixed handling of stale loss report.
• PR #1078: Fixed closing the crypto control.
• PR #1067: Added CSync class as a high-level CV wrapper.
• PR #1077: Renamed legacy UDT_EPOLL_* symbols.
• PR #1045: Eliminated ref_t. Some more convention fixes.
• PR #1010: Crypto: Reset the passphrase in memory on close for security reasons.

Deprecated or Renamed

• Removed deprecated socket options: SRTO_TWOWAYDATA, SRTO_TSBPDMAXLAG, SRTO_CC, SRTO_MAXMSG, SRTO_MSGTTL, SRTO_SNDPBKEYLEN, SRTO_RCVPBKEYLEN.
• Removed deprecated option names: SRTO_SMOOTHER (use SRTO_CONGESTION), SRTO_STRICTENC (use SRTO_ENFORCEDENCRYPTION), SRTO_TSBPDDELAY (use SRTO_LATENCY).

See PR #1364 for details.
