Noteworthy changes in strace 5.5 (2020-02-06)
=============================================

* Improvements
  * Added -e trace=%creds option for tracing syscalls related to process
    credentials.
  * Enhanced decoding of arch_prctl, keyctl, io_uring_register, io_uring_setup,
    and perf_event_open syscalls.
  * Enhanced decoding of BPF_PROG_LOAD bpf syscall command.
  * Updated decoding of clone3 syscall to match Linux 5.5.
  * Implemented decoding of TCA_ACT_FLAGS and TCA_STATS_PKT64 netlink
    attributes.
  * Updated lists of AUDIT_*, BPF_*, CLONE_*, KEY_*, KVM_*, PPC_PTRACE_*,
    SCTP_*, STATX_*, TIPC_*, V4L2_*, and *_MAGIC constants.
  * Updated lists of ioctl commands from Linux 5.5.
  * Enhanced manual page and "strace --help" output.

* Bug fixes
  * Fixed stack trace printing for early syscalls when strace is configured
    to use libdw backend for stack tracing (addresses Fedora bug #1788636).
  * Fixed stack trace caching when --seccomp-bpf option is specified.
  * Fixed potentially unaligned access in decoder of SO_TIMESTAMP*_NEW
    control messages.
  * Fixed decoding of NDA_LLADDR netlink neighbor table attribute.
  * Fixed build of mpers support when CFLAGS contains -flto.
  * Fixed build on no-MMU architectures.
