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 arguments 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. v2 changes: - Fixed trace-cmd agent to work with v7 compressed files. - Fixed converting files from v6 to v7 with empty top buffer. - Minor coding style fixes.
