v1.5.1

Release Notes

API / ABI / Integration Changes

API/ABI version: 1.5.

Some minor changes touching, but not affecting the API/ABI compliance:

• PR #2440: The SRT API file srt.h defines macros MJ and MN and almost immediately undefines them. Those short names could potentially conflict with macros in 3rd party applications. Renamed macro MN to SRT_EMN and MJ to SRT_EMJ.
• PR #2451: Fixed DLL build when using mingw-w64 that supports __declspec(dllexport) and __declspec(import) specifiers.

Improvements and Important Bug Fixes

• PR #2333: Added support for OpenSSL EVP API. Can be enabled with the help of the -DUSE_ENCLIB=openssl-evp CMake build option.
• PR #2408: Improved timing for idle connections. TSBPD time base (TsbpdTimeBase) and clock drift (Drift) values are adjusted to take the TSBPD wrapping period into account even if there are no data packets transmitted over the connection.
• PR #2384, #2395: Data race fixes for CRcvQueue and CUnitQueue.
• PR #2405: Improved receiver performance via CUnitQueue changes.
• PR #2416: Fixed the calculation of the byteRcvLoss statistic. This is a fix for the issue #2414 introduced in PR #2212. Affected version is v1.5.0.
• PR #2413, #2425: Fixed data races in crypto library in the case of mbedTLS.
• PR #2391: Fixed the sendBroadcast() function message length.
• PR #2398: Added ENABLE_BONDING socket option to the Windows PowerShell build script.

Documentation

• PR #2454: Added description of package managers supporting the SRT library to Build Instructions.
