    Noteworthy changes in release 4.22 (2018-04-05)
    ===============================================
    
    * Changes in infrastructure
      * The mailing list was moved to strace-devel@lists.strace.io.
      * SourceForge git repository
        (https://sourceforge.net/p/strace/code/ci/master/tree/) is no longer
        maintained.  Please use GitLab (https://gitlab.com/strace/strace/)
        or GitHub (https://github.com/strace/strace/) repository instead.
    
    * Changes in behaviour
      * When printing string data, '8' and '9' following an octal escape sequence
        no longer lead to unabbreviated octal escape sequence output, as they used
        to do.
      * Angle brackets are now printed as octal number escape sequences
        in the output of paths associated with file descriptors.
      * Data dump for write syscalls (-e write) is performed regardless
        of successfulness of these syscall (addresses Debian bug #436284).
      * -r and -t options are now affect output independently.  Previously,
        -r option led to ignoring of the -t option (addresses Debian bug #466195).
    
    * Improvements
      * Implemented delay injection (-e inject=SET:delay_enter= and
        -e inject=SET:delay_exit= options).
      * Added -A option for opening output files in append mode
        (addresses Debian bug #528488).
      * IPv6 addresses shown in socket information in -yy mode are now printed
        in brackets.
      * Enhanced decoding of bpf, prctl and ptrace syscalls.
      * Enhanced decoding of BTRFS_IOC_INO_PATHS, BTRFS_IOC_LOGICAL_INO, and PTP_*
        ioctl commands.
      * Enhanced NETLINK_ROUTE protocol decoding.
      * Updated lists of signal codes.
      * Updated lists of BPF_*, BTN_*, ETH_P_*, INET_DIAG_BC_*, KEY_*, POLL*, RWF_*,
        SCHED_FLAG_*, SCTP_* and error constants.
      * Implemented block/character device number printing in -yy mode.
      * Known pixel/SDR format names are printed as comments for pixelformat fields
        in v4l2 structures.
      * Enhanced decoding of kern_features syscall.
      * Enhanced NETLINK_NETFILTER netlink protocol decoder.
      * Optimized handling of large number of tracees.
      * Improved wall clock time measurement in syscall count statistics
        (-c -w option).
      * Extended the range of allowed values in -e inject=...:retval= expression.
      * Added i18n support.
      * Updated lists of ioctl commands from Linux 4.16.
      * Enhanced manual page.
    
    * Bug fixes
      * Fixed build on m68k.
      * Fixed v4l2 pixelformat decoding on big-endian architectures.
      * Fixed -O option.
    
    Bug: N/A
