Starting with version 4.13, strace follows the schedule of linux kernel
and new versions of strace are released along with new versions of linux
kernel, so strace 6.6 is tagged and uploaded.

$ git tag -v v6.6 2> /dev/null | sed -n '/^$/,$p'

Noteworthy changes in strace 6.6 (2023-10-31)

* Improvements
  * Implemented --kill-on-exit option that instructs the tracer to set
    PTRACE_O_EXITKILL option to all tracee processes and not to detach them
    on cleanup so they will not be left running after the tracer exit.
  * Implemented automatic activation of --kill-on-exit option when
    --seccomp-bpf is enabled and -p/--attach option is not used.
  * Implemented decoding of map_shadow_stack syscall.
  * Implemented decoding of FSCONFIG_CMD_CREATE_EXCL fsconfig command.
  * Implemented decoding of IFLA_BRPORT_BACKUP_NHID netlink attribute.
  * Implemented decoding of SECCOMP_IOCTL_NOTIF_SET_FLAGS ioctl.
  * Implemented decoding of UFFDIO_CONTINUE, UFFDIO_POISON, and
  * Updated lists of ARCH_*, BPF_*, DEVCONF_*, IORING_*, KEXEC_*, MAP_*, NT_*,
    PTRACE_*, QFMT_*, SEGV_*, UFFD_*, V4L2_*, and XDP_* constants.
  * Updated lists of ioctl commands from Linux 6.6.
