| Noteworthy changes in release 4.5.20 | |
| ==================================== | |

| * Implemented basic decoding of new linux syscalls: preadv, pwritev, | |
| rt_tgsigqueueinfo, perf_event_open. | |
| * Enhanced decoding of recently added syscalls on non-x86 architectures | |
| by replacing a bare decoder with elaborate parsers enabled earlier | |
| for x86/x86-64. | |
| * Implemented -C option to combine regular and -c output. | |
| (Addresses Debian bug #466196) | |
| * Enhanced decoding of mbind and mremap syscalls. | |
| * Enhanced SOL_PACKET socket options decoding. | |
| * Regenerated list of ioctl names from linux 2.6.33. | |

| (Addresses Debian bug #560516 and Fedora bug #539044) | |
| * Fixed build on mips. | |
| * Fixed handling of Linux systems without struct statfs64. | |
| * Fixed reporting signal mask by sigreturn on powerpc. | |

| 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) | |

| * Implemented decoding of new Linux syscalls: accept4, dup3, | |
| epoll_create1, eventfd2, inotify_init1, pipe2, signalfd4. | |
