Release Candidate Notes

API/ABI/Integration Changes

API/ABI version: 1.5​.

  • PR #2316: ENABLE_BONDING build option (instead of ENABLE_EXPERIMENTAL_BONDING). Dummy bonding API version if disabled (default).
  • PR #2312: Deprecated srt_rejectreason_msg[].
  • PR #2152: Use the SOCKET type for any WIN32 environment.
  • PR #2271: Fixed missing extern "C" for API function srt_rejectreason_str(..).
  • PR #2176: Fixed handshake cookie validation by the listener (rendezvous connection).
  • PR #2081: Added group socket option SRTO_GROUPMINSTABLETIMEO.

Improvements

  • PR #2324: Resolved symbol name leakage / polution (placed inside the srt namespace).
  • PR #2260: Source rate estimate: ignore outdated samples. Derive source rate estimate from active member (Main/Backup groups).
  • PR #2241: Improved the condition for smoothed RTT recalculation with bidirectional transmission.
  • PR #1260: Prioritize original packets over retransmissions in live streaming configuration (SRT Sender).
  • PR #2232: Fix MaxBW limitation #713. Don't reschedule sending (keep pacing) on SND drop, NAK received, retransmission timeout. Added pacing amendment after sending probing packets.
  • PR #2230: Use SND buffer delay for TL Packet Drop instead of the timespan between the first and the last packet in the buffer.
  • PR #1950: Fix GC stop handling.
  • PR #2068: Drop msg by TTL even if hasn't ever been sent.
  • PR #2185: SND buffer: operate either origin or source time, not both.
  • PR #1964: New receiver buffer implementation (enabled by default with ENABLE_NEW_RCVBUFFER=ON build option).
  • PR #2159: Use Mersenne Twister engine with C++11 instead of the std::random_device. Fixed max value probability for the default (C++03) rand().
  • PR #1913: Replaced global CUDTUnited with static local variable.

Fixed Issues Highlights

  • PR #2208, #2210: Fixed RTT estimation for bidirectional transmission.
  • PR #2231: Check if CryptoControl exists in craftKmResponse. Fixes crash #2231.
  • PR #2125: Moved SND and RCV buffers into the 'srt' namespace (Symbol Name Leakage/Polution #1924).
  • PR #2301: Fix name conflict with md5 functions (Symbol Name Leakage/Polution #1924).
  • PR #2291, #2292: Fix volatile keyword usage. Prefer using std::atomic where possible.
  • PR #2258: Fix extraction seq with scheduling seq in group.
  • PR #2257: Fix unrecoverable initial packets lose in group message mode.
  • PR #2245: Improved group readiness updating in sendCtrlAck(). Group::updateReadState() support out-of-order messages.
  • PR #2223: fixed missing m_RcvBufferLock in processCtrlDropReq().
  • PR #2214: Fixed RCV TL drop of packets dropped by SND.
  • PR #2195: Fix consistency of packet seqno in CRcvLossList.
  • PR #2197: Fix deadlock introduced by CUDTGroup::setOpt().
  • PR #2196: fix CRcvLossList::m_iTail not reset to -1.
  • PR #2162: Fix UDP RCVBUF and SNDBUF socket options on Solaris.
  • PR #2168: Changed lock order in bstats(..) API functions to access statistics.

Build

  • PR #2148: Support NDK r23, OpenSSL v3.
  • PR #2319, #2325: Fixed building sendfile and recvfile examples. They don't need C++11.

Docs

  • PR #2311: Added note on SRT versioning.
