 User visible changes:
 
 Improvements:
 
 . Support showing source code, asking for variables to be collected
   at probe time and other 'perf probe' operations that use DWARF information.
 
   This supports only binaries with debugging information at this time, detached
   debuginfo (aka debuginfo packages) support should come in later patches.
   (Masami Hiramatsu)
 
 . Add a perf.data file header window in the 'perf report' TUI, associated
   with the 'i' hotkey, providing a counterpart to the --header option in the
   stdio UI. (Namhyung Kim)
 
 . Guest related improvements to 'perf kvm', including allowing to
   specify a directory with guest specific /proc information. (Dongsheng Yang)
 
 . Print session information only if --stdio is given (Namhyung Kim)
 
 Developer stuff:
 
 Fixes:
 
 . Get rid of a duplicate va_end() in error reporting (Namhyung Kim)
 
 . If a hist entry doesn't have symbol information, compare it with its
   address. Affects upcoming new feature (--cumulate) (Namhyung Kim)
 
 Improvements:
 
 . Make libtraceevent install target quieter (Jiri Olsa)
 
 . Make tests/make output more compact (Jiri Olsa)
 
 . Ignore generated files in feature-checks (Chunwei Chen)
 
 New APIs:
 
 . Introduce pevent_filter_strerror() in libtraceevent, similar in
   purpose to libc's strerror() function. (Namhyung Kim)
 
 Refactorings:
 
 . Use perf_data_file methods to write output file in 'record' and
   'inject' (Jiri Olsa)
 
 . Use pr_*() functions where applicable in 'report' (Namhyumg Kim)
 
 . Add 'machine' 'addr_location' struct to have full picture (machine,
   thread, map, symbol, addr) for a (partially) resolved address, reducing
   function signatures (Arnaldo Carvalho de Melo)
 
 . Reduce code duplication in the histogram entry creation/insertion. (Arnaldo Carvalho de Melo)
 
 . Auto allocate annotation histogram data structures, (Arnaldo Carvalho de Melo)
 
 . No need to test against NULL before calling free, also set
   freed memory in struct pointers to NULL, to help fixing use after
   free bugs. (Arnaldo Carvalho de Melo>
