+Noteworthy changes in release 4.7
+=================================
+
+* Changes in behavior
+ * strace no longer suspends waitpid until there is a child
+ for waitpid'ing process to collect status from.
+ * strace no longer detaches from a tracee which is supposed
+ to be going to die.
+ * strace now issues a new message: "+++ exited with EXITCODE +++"
+ which shows exact moment strace got exit notification,
+ analogous to existing "+++ killed by SIG +++" message.
+
+* Improvements
+ * Added x32 architecture support.
+ * Added -y and -P options to print file descriptor paths and
+ filter by those paths.
+ * Added -I option to control strace interactivity.
+ * Allowed -p option to take comma or whitespace-separated list of PIDs.
+ * Added strace_log_merge script helper to merge timestamped "strace -ff"
+ log files.
+ * Implemented decoding of clock_adjtime, get_robust_list, migrate_pages,
+ preadv, prlimit64, process_vm_readv, process_vm_writev, pwritev,
+ rt_tgsigqueueinfo, sendmmsg, setns, set_robust_list,
+ sched_rr_get_interval, splice, syslog, tee and vmsplice syscalls.
+ * Enhanced decoding of capget, capset, getrlimit, flistxattr, io_submit,
+ listxattr, setrlimit and swapon syscalls.
+ * Implemented decoding of loop and mtd ioctls.
+ * Added syscall entries for new linux syscalls.
+ * Added syscall entries for direct socket system calls on powerpc.
+ * Updated the list of errno constants.
+ * Updated lists of MSG_* and TCP_* constants.
+ * Regenerated the list of ioctl names from Linux 3.3.
+ * Enhanced switching between processes with different personalities.
+ * Enhanced signals reporting by using short signal names.
+ * Made ERESTART* messages more descriptive.
+ * Made parsing of numbers from strings more robust.
+ * Added support for compat_statfs64 and statfs64.f_flags.
+ * Changed read of data blocks to use single process_vm_readv syscall
+ (when available) instead of several PTRACE_PEEKDATA operations.
+ * Changed read of registers on x86 and x86-64 to use single PTRACE_GETREGS
+ operation instead of several PTRACE_PEEKUSER operations.
+ * Applied various optimizations to make strace work faster.
+
+* Bug fixes
+ * Implemented proper handling of real SIGTRAPs on kernels supporting
+ PTRACE_O_TRACESYSGOOD.
+ (Addresses Fedora bug #162774).
+ * Fixed sockaddr_un.sun_path name in decoded output.
+ (Addresses Debian bug #554946).
+ * Fixed to avoid potential core file clobbering on exit.
+ (Addresses Debian bug #656398).
+ * Fixed a typo in documentation.
+ (Addresses Debian bug #653309).
+ * Fixed decoding of timer id returned by timer_create.
+ * Fixed epoll_create1, epoll_wait and epoll_pwait decoding.
+ * Fixed *at syscalls flags decoding.
+ * Fixed ARM EABI 64-bit syscall's arguments decoding.
+ * Fixed semtimedop decoding on s390.
+ * Fixed osf_sigprocmask decoding on alpha.
+ * Fixed ipc and socket subcall decoding on several architectures.
+ * Corrected syscall entries for epoll_pwait, epoll_create, epoll_ctl,
+ epoll_wait, mincore, mlockall, prctl, reboot, sendfile, sendfile64,
+ sendmsg, sgetmask, ssetmask, swapon, tgkill and tkill syscalls.
+ * Corrcted io_* syscall entries on ARM.
+ * Fixed PID prefix printing in "strace -oLOG -ff -p1 -p2 -p3" case.
+ * Fixed logging of unfinished lines in "strace -oLOG -ff" case.
+ * Fixed build when libaio-devel is not available.
+ * Fixed configure checks for PTRACE_* constants.
+ * Fixed compilation warnings remained on several architectures.
+
+* Portability
+ * Removed all non-Linux code. After years of neglect, that dead code
+ just hampered further strace development.
