           - percent
           - used
           - active [POSIX]

          now.
  * #309: get_open_files() might not return files which can not be accessed
          due to limited permissions. AccessDenied is now raised instead.

 BUGFIXES

 .1.1 - 2009-03-06
 ------------------
 NEW FEATURES
  * #4: FreeBSD support for all functions of psutil
  * #9: Process.uid and Process.gid now retrieve process UID and GID.
  * #11: Support for parent/ppid - Process.parent property returns a
         Process object representing the parent process, and Process.ppid returns
         the parent PID.
  * #12 & 15:
         NoSuchProcess exception now raised when creating an object
         for a nonexistent process, or when retrieving information about a process
         that has gone away.
  * #21: AccessDenied exception created for raising access denied errors
         from OSError or WindowsError on individual platforms.
  * #26: psutil.process_iter() function to iterate over processes as
         Process objects with a generator.
  * #?:  Process objects can now also be compared with == operator for equality
         (PID, name, command line are compared).
 BUGFIXES
  * #16: [Windows] Special case for "System Idle Process" (PID 0) which
         otherwise would return an "invalid parameter" exception.
  * #17: get_process_list() ignores NoSuchProcess and AccessDenied
         exceptions during building of the list.
  * #22: [Windows] Process(0).kill() was failing with an unset exception.
  * #23: Special case for pid_exists(0)
  * #24: [Windows] Process(0).kill() now raises AccessDenied exception instead of
         WindowsError.
  * #30: psutil.get_pid_list() was returning two instances of PID 0 on OS
         X and FreeBSD platforms.
