CONDUCT: A new code of conduct has been adopted.  See the CONDUCT
        file for more information.

debuginfod: Add per-file signature verification for integrity
        checking, using RPM IMA scheme from Fedora/RHEL.

        New API for metadata queries: file name -> buildid.

        Server-side extraction of files from kernel debuginfo
        packages is significantly faster. Now takes < 0.25 seconds,
        down from ~50 seconds.

libdw: New functions dwfl_set_sysroot, dwfl_frame_unwound_source
        and dwfl_unwound_source_str.

stacktrace: Experimental new tool that can process a stream of stack
        samples from the Sysprof profiler and unwind them into call
        chains. Enable on x86 with --enable-stacktrace. See
        README.eu-stacktrace in the development branch for detailed
        usage instructions:
