Notable user-visible changes
- SECURITY NOTE: Thanks to Leonid Krolle Bi.Zone for discovering a JSON type security vulnerability that caused a segmentation fault in the server. (CVE-2024-53580) This has now been fixed. (PR#1810)
- UDP packets per second now reports the correct number of packets, by reporting NET_SOFTERROR if there's a EAGAIN/EINTR errno if no data was sent (#1367/PR#1379).
- Several segmentation faults related to threading were fixed. One where pthread_cancel was called on an improperly initialized thread (#1801), another where threads were being recycled (#1760/PR#1761), and another where threads were improperly handling signals (#1750/PR#1752).
- A segmentation fault from calling freeaddrinfo with NULL was fixed (PR#1755).
- Some JSON options were fixed, including checking the size for json_read (PR#1709), but the size limit was removed for received server output (PR#1779).
- A rcv-timeout error has been fixed. The Nread timeout was hardcoded and timed out before the --rcv-timeout option (PR#1744).
- There is no longer a limit on the omit time period (#1770/PR#1774).
- Fixed an output crash under 32-bit big-endian systems (PR#1713).
- An issue was fixed where CPU utilization was unexpectedly high during limited baud rate tests. The --pacing-timer option was removed, but it is still available in the library (#1741/PR#1743).
- Add SCTP information to --json output and fixed compile error when SCTP is not supported (#1731).
- --fq-rate was changed from a uint to a uint64 to allow pacing above 32G. Not yet tested on big-endian systems (PR#1728).

Notable developer-visible changes
- Clang compilation failure on Android were fixed (PR#1687).
- iperf_time_add() was optimizated to improve performance (PR#1742).
- Debug messages were added when the state changes (PR#1734).
- To increase performance, the old UDP prot_listener is cleared and removed after each test (PR#1708).
- A file descriptor leak was closed (PR#1619).
