Major changes since version 6: - New, flexible and extendable structure of the file. - Optional compression of file metadata and tracing data. By default, trace-cmd still uses the old version 6 when recording trace file. There are new options to force using the new version. A new "trace-cmd convert" sub-command is introduced, to convert files between different versions. Known issues: - "trace-cmd split" does not work with trace file version 7, if there are CPUs with empty trace data. - "trace-cmd agent" has problems with compressed files Tzvetomir Stoyanov (VMware)
