WARNING: This release is known to be affected by an issue with TURN connections as reported in Issue #2038

What’s new:

  • addConfigToServerList API required to gather TURN candidates. Check samples for usage. The usage pattern showcases with ENABLE_KVS_THREADPOOL enabled and disabled
  • Improved time-to-first-frame latency with new CMAKE flag ENABLE_KVS_THREADPOOL. This flag is Enabled by default. KVS_USE_SIGNALING_CHANNEL_THREADPOOL has been deprecated now. (#1806)
  • Added feature to send master time-to-first-frame for JS viewer timeline visualization; enable with enableSendingMetricsToViewerViaDc (#1846)
  • Optimized time taken to gather TURN servers using GetIceServerConfig by supporting an async call pattern. In case of srflx based peer connection, this is a latency improvement since the SDK does not unnecessarily wait on getting TURN server URLs during signaling setup. ENABLE_KVS_THREADPOOL required (#1854). Sample change required to gather relay candidates
  • Changed default build type from Debug to Release; use -CMAKE_BUILD_TYPE=Debug for debug mode. (#1897)

Sample bug fixes:

  • Sending key frames before other frames in Samples. Frames are now sent only after SRTP is READY (#1833)
  • Added checks for empty/null session token (#1874)

Bug fixes / Improvements:

  • Fixed trickle ICE to be a session level and media level attribute instead of it being only a media level attribute (#1813)
  • Optimized time taken for STUN DNS resolution to have STUN server address ready for srflx candidate gathering - ENABLE_KVS_THREADPOOL required (#1812)
  • Improved DTLS handshake time by moving to a state transition based approach to be more responsive to the incoming DTLS handshake messages - ENABLE_KVS_THREADPOOL required (#1824)
  • Optimized ICE and TURN state machine state transitions. They allow early state transitions if possible, instead of waiting for next timer iteration (#1825)
  • Fixed stringop-overflow build issue with MBedTLS on GCC11 (#1823)
  • Increasing timeout values on TURN allocation, create permission, and bind channel steps. This change is expected to improve connection establishment success rates in slower networks (#1896)
  • Fixed signaling cache file creation failure issue on Windows (#1935)
  • Added filtering-out of non-operation network interfaces in Windows (#1937)

Version bumps:

  • Updated LWS version from 4.2.2 to 4.3.3 (#1820)
  • Updated producer C version from 1.5.1 to 1.5.2 (v1.5.2)

Known issues:

  • MBedTLS build fails on Mac M1 with current version
