v1.5.3

Release Notes

API / ABI / Integration Changes

API/ABI version: 1.5.

New Features

• PR #2714: Added maximum BW limit for retransmissions. See SRTO_MAXREXMITBW.
  The new option limits the maximum bandwidth that can be used for the retransmission of lost packets. Can be used in conjunction with the SRTO_MAXBW options family, which limits the overall pacing, and thus, the maximum bandwidth utilized by all SRT packets from the sender.

Important Bug Fixes

• PR #2632: Use overlapped WSASendTo to avoid UDP sending losses.
• PR #2766: Fixed spurious group read-ready epoll events.
• PR #2772: Fixed RCV buffer initialization in Rendezvous. ⚠️
• PR #2757: Fix memory leak on queuing connection initialization packets.
• PR #2745: Fix hang up on not enough space in the RCV buffer.
• PR #2740: Fix possible tsbpd() deadlock with processCtrlShutdown().
• PR #2692: Rejection not undertaken in rendezvous after KMX failure.
• PR #2774: Fix rendezvous connection mode when processing resulted in ACCEPT it was still sending rejection.
• PR #2778: Drop unencrypted packets in AES-GCM mode.

Build

• PR #2779, #2780: Fix the build for targets without IP_ADD_SOURCE_MEMBERSHIP.
• PR #2784: Added missing public header files in Windows binary installer.

Unit Tests

• PR #2681: Added custom main with transparent parameters.

Documentation

• PR #2765: Updated the explicit information for binding to IPv6 wildcard.
• PR #2785: Fixed API doc: SRT_INVALID_SOCK instead of SRT_ERROR in str_accept.
