Noteworthy changes in release 4.18 (2017-07-05)

* Improvements
  * Implemented decoding of SCM_TIMESTAMP* control messages.
  * Implemented decoding of netlink NLMSG_DONE messages.
  * Implemented decoding of netlink generic nlmsg_type and nlmsg_flags.
  * Implemented decoding of NETLINK_GENERIC protocol families.
  * Implemented basic protocol specific decoding of AF_INET, AF_INET6,
  * Implemented basic decoding of netlink attributes.
  * Implemented basic protocol specific decoding of AF_INET, AF_NETLINK,
    AF_PACKET, AF_SMC, and AF_UNIX netlink attributes of NETLINK_SOCK_DIAG.
  * Implemented decoding of inet_diag_msg, netlink_diag_msg, and unix_diag_msg
    netlink attributes of NETLINK_SOCK_DIAG.
  * Updated lists of ARPHRD_*, KEYCTL_*, NDIAG_SHOW_*, RTM_*, SCM_*, SCTP_*,
    SO_*, V4L2_*, and prctl ARCH_* constants.
  * Updated lists of ioctl commands from Linux 4.12.

* Bug fixes
  * In interactive mode (-I2), those signals that were blocked at startup
    will remain blocked for the whole period of strace execution.
  * strace no longer resets SIGCHLD handler in tracees to the default action.
  * When traced command is terminated by a blocked signal, strace unblocks
    that signal to ensure its own termination with the same signal.
  * Fixed corner cases in decoding of old sigaction syscall.
  * Fixed build with old kernel headers on mips.
  * Fixed build on aarch64 and tile with glibc >= 2.26.
  * Fixed build on arc and nios2.

Noteworthy changes in release 4.17 (2017-05-24)

* Changes in command line syntax
  * Syscall classes specified in -e trace= option now have % prefix (like
    -e trace=%process).  Old style class names without leading % are still
    supported, but considered deprecated now.

* Improvements
  * Optimized syscall filtering.
  * Improved representation of timestamps.
  * Enhanced decoding of sched_setattr syscall.
  * Added -e trace=%stat option for tracing variants of stat syscall.
  * Added -e trace=%lstat option for tracing variants of lstat syscall.
  * Added -e trace=%fstat option for tracing variants of fstat and fstatat
  * Added -e trace=%%stat option for tracing syscalls used for querying file
    status information (stat, lstat, fstat, fstatat, statx, and their
  * Added -e trace=%statfs option for tracing statfs, statfs64 and statvfs
  * Added -e trace=%fstatfs option for tracing fstatfs, fstatfs64 and fstatvfs
  * Added -e trace=%%statfs option for tracing syscalls used for querying file
    system statistics information (statfs-like, fstatfs-like and ustat).
  * Added -e trace=/regex option for filtering syscalls using regular
  * Added support for prepending of question mark before syscall qualification
    in -e trace expressions in order to suppress error in case no syscalls
    matched the provided qualification.
  * Implemented decoding of signal mask in rt_sigreturn syscall on alpha, arc,
    arm, avr32, bfin, cris, hppa, m68k, metag, microblaze, mips, nios2, or1k,
    powerpc, powerpc64, riscv, sh, sh64, sparc, sparc64, tile, x86, and xtensa
  * Implemented decoding of statx syscall.
  * Implemented decoding of NS_* ioctl commands.
  * Implemented decoding of the remaining V4L2_BUF_TYPE_* types.
  * Implemented decoding of VIDIOC_[SG]_TUNER ioctl commands.
  * Implemented decoding of NLMSG_ERROR netlink messages.
  * Improved decoding of BPF_PROG_ATTACH command of bpf syscall.
  * Improved decoding of misplaced parts in DM_* ioctl commands.
  * Updated lists of ioctl commands from Linux 4.11.

* Bug fixes
  * Fixed decoding of flags argument of preadv2 and pwritev2 syscalls on x32.
  * Fixed the number of arguments and tracing flags of alpha specific syscalls.
  * Fixed decoding of old sigsuspend syscall on alpha, cris, mips, powerpc,
    powerpc64, sh, sh64, sparc, and sparc64.
  * Fixed decoding of sgetmask and ssetmask syscalls on 64-bit architectures.
  * Fixed decoding of netlink messages received within struct msghdr.
  * Worked around a bug in miscompiled aarch64 kernels leading to the 3rd
    argument of sched_getattr syscall being not quite 32-bit.
  * Fixed corner cases of printing inaccessible times argument of utimes
    and futimesat syscalls.
