Noteworthy changes in release 4.5.19
====================================

* Changes in behavior
  * When command exits, strace now exits with the same exit status.
    If command is terminated by a signal, strace terminates itself
    with the same signal, so that strace can be used as a wrapper
    process transparent to the invoking parent process.
    When using -p option, the exit status of strace is zero unless
    there was an unexpected error in doing the tracing.
    (Addresses Fedora bug #105371 and Debian bug #37665)

* Improvements
  * Implemented decoding of new Linux syscalls: accept4, dup3,
    epoll_create1, eventfd2, inotify_init1, pipe2, signalfd4.
  * Implemented decoding of socket type flags introduced in Linux 2.6.27.
  * Implemented decoding of accept4 socketcall.
  * Enhanced prctl decoding.
  * Enhanced nanosleep decoding.
  * Enhanced ptrace decoding.
  * Enhanced futex decoding.
  * Enhanced CAP_* decoding.
