	  option -p. This also concerns pidstat option -U.
	* Fixed type for "memfree" and "intr" elements in XSD document.
	* Removed functions used to count number of items from rd_stats.c
	  and put them in a separate file (count.c).

	  CPU frequency statistics are available.
	* sadc updated: Option "-S POWER" tells sadc to collect power
	  management statistics.
	* sadf command updated to take into account power management
	  statistics.
	* [Mike Harvey]: No longer truncate the interval of time to

	* [Ivana Varekova]: Make iostat display statistics for devices only
	  (and not partitions) when not using its option -d. This was
	  no longer possible with kernels 2.6.25 and later because iostat
	  couldn't distinguish between devices and partitions any more.
	* iostat's options -x and -p are no longer mutually exclusive:
	  Extended statistics are now available even for partitions with
	  recent kernels.
	* iostat was unable to read stats from sysfs for devices who had
	  a slash in their names (for example, iostat -p /dev/cciss/c0d0
	  didn't work properly before). This is now fixed.
	* [Amir Rapson]: Fixed a bug in iostat where %CPU spent
	  servicing hard and soft irq were counted twice. This bug
	  was introduced in 8.1.5.

	* [David Alan Gilbert]: Option -h added to pidstat. This
	  option is used to display all activities horizontally on a
	  single line.
	* Fixed a bug in pidstat: When pidstat was used to monitor a
	  process and all its threads (with pidstat's option -t), it
	  could display weird values if the thread group leader terminated.
	* Header line displayed by sar, iostat, mpstat, pidstat and
	  sadf -H now includes the number of CPU.
	* Use the correct word TGID instead of PID with pidstat -t.
	* mpstat now displays stats for all interrupts, including NMI,
	  LOC, etc.
	* sar and sadf now check that CPU activity is available in file.
	* iostat's option -t now always displays the date and the time.
	* Added option "--disable-documentation" to ./configure. Using
	  this option prevents documentation files (including manual
	  pages) from being installed.
	* iconfig script updated. Now ask the user for documentation
	  and isag script installation.
	* Manual pages updated.
	* NLS updated. Indonesian and Chinese (traditional) translations
	  added.
	* README-nls file updated.
	* Makefile updated: There is now a dedicated target to install
	  or uninstall NLS files
	* FAQ updated.
	* CREDITS file updated.
	* Code cleaned.

2008/07/14: Version 8.1.5 - Sebastien Godard (sysstat <at> orange.fr)
	* Added virtual machine time accounting to "sar -u ALL" and
	  mpstat (%guest).
	* pidstat has also been updated to be able to display time
	  spent in virtual machine for a task, and for a task and all
	  its children.
	* Option -S added to sar: This options tells sar to display
	  swap space utilization. Option -r now only displays memory
	  utilization.
	* Added %swpcad to sar -S (percentage of cached swap memory
	  in relation to the amount of used swap space).
	* Added kbcommit and %commit to sar -r (amount and percentage
	  of memory needed for current workload).
	* sadf -x now distinguishes between options -r and -R.
	* sadf command updated to take into account new fields
	  (%guest, %swpcad, etc.)
	* [Ivana Varekova]: iostat now displays the total number of
	  operations per second in the NFS report.
	* Fixed iostat so that %system (percentage of CPU utilization
	  that occurred while executing at system level) also takes
	  into account time spent to service interrupts and softirqs.
	* Added a missing header line for activities with multiple
	  outputs displayed by sar (eg. sar -rR ...).
	* Makefile updated: There is now a dedicated target to install
	  or uninstall manual pages.
	* Manual pages updated.
	* Code cleaned.
	* XSD and DTD documents updated.
	* isag script updated.

2008/06/22: Version 8.1.4 - Sebastien Godard (sysstat <at> orange.fr)

	  option "-u ALL". sadf has also been updated to be able to
	  display them.
	* mpstat can now display per-CPU interrupts statistics with its
	  option "-I CPU". This was a feature available in sar that was
	  removed in previous sysstat version.
	* mpstat uses now a separate option ("-I SUM") to display the
	  total number of interrupts for each processor.
	* Option -A added to mpstat. This switch tells mpstat to display
	  all possible activities.
	* NFS v4 support added to sar -n NFS(D). When both NFS v3 and
	  NFS v4 are used, stats from NFS v3 and NFS v4 are added
	  together [DEBIAN bug#434442].
	* Code cleaned: mpstat, iostat and pidstat now use the common
	  functions from rd_stats.c to read CPU stats from /proc/stat;
	  Computing extended disk statistics (service time, etc.) is now
	  done in one place (common function used by iostat, sar, sadf).
	* All sysstat commands are made consistent with how parameters
	  are interpreted: "COMMAND <interval>" now generates a report
	  continuously, "COMMAND <interval> 0" causes an error,
	  "COMMAND 0" displays a report since system startup
	  [DEBIAN bug#475707].
	* Changed XML output for processes and context switches displayed
	  by sadf -x to be consistent with output from sar.
	* mpstat and sar manual pages updated.
	* isag script updated.
	* FAQ updated.

	* NLS updated.

2008/05/25: Version 8.1.3 - Sebastien Godard (sysstat <at> orange.fr)
	  WARNING: Daily data files format has changed, and is *not*
	  compatible with the previous one! [0x2170]
	* sar, sadc and sadf heavily modified. It is now easier to add
	  (or remove) activities since sar and sadc have been rewritten
	  in a non-monolithic way with a generic design architecture.
	* Option -c removed from sar. Task creation and context switch
	  activities are now merged and available with option -w.
	* sar no longer displays interrupts per processor statistics.
	  This feature will be included in mpstat in next sysstat version.
	* Option -S added to sadc. This option replaces previous options
	  -I or -d, and is used to select activities that should be
	  collected and saved in file. It is even possible to
	  select each activity collected by sadc.
	* Format of data files created by sar/sadc heavily modified.
	  In some cases, it is now possible to add or remove activities
	  while keeping a compatible format that can be read by a previous
	  or future sysstat version.
	* sadf now only displays activities that have been explicitly
	  selected.
	* sar now checks that devices displayed by option -d are whole
	  devices (and not partitions) using sysstat.ioconf configuration
	  file. If this file is not found in its default directory, then
	  sysstat looks for it in current directory.
	* gettextize entire usage() messages so that translators have
	  free scope to act.
	* DTD and XML Schema updated.
	* Manual pages updated.
	* Crontab samples updated.
	* FAQ updated.
	* Code cleaned.

2008/03/16: Version 8.1.2 - Sebastien Godard (sysstat <at> orange.fr)
	* [Ivana Varekova]: iostat now displays read and write operations
	  per second in the NFS report.
	* [Tomas Mraz]: sadc now retries to write its buffers when the
	  write() call has been interrupted by a signal.
	* Use setbuf() call instead of fflush() to indicate that data
	  should not be buffered to stdout.
	* Option -h added to sadf. Used with options -d or -D, it
	  indicates that all activities should be displayed horizontally
	  on a single line of data.
	* sadf -d and sadf -D now display the list of fields for easier
	  data reading.
	* sadf and iostat manual pages updated.
	* NLS updated: Chinese (simplified) translation added, other
	  translations updated.

2008/02/10: Version 8.1.1 - Sebastien Godard (sysstat <at> orange.fr)

	  compatible with the previous one! [0x216f]
	* System activity data files now have extra header data that
	  enable to identify which version of sysstat created them.
	* sadf -H now displays the version of sysstat used to create
	  a system activity data file.
	* Machine architecture is now displayed in the reports header.
	  sadf -x also displays machine architecture.
	* DTD and XML Schema documents updated.
	* The number of processors was not properly calculated on
	  machines where a directory named cpuidle was present in the
	  /sys/devices/system/cpu directory [GENTOO bug# 207886].
	* Use __CPU_SETSIZE definition from <sched.h> instead of a
	  static definition for the maximum number of CPUs (NR_CPUS).
	* Improved error messages displayed by sysstat's commands.
	* NLS updated: Finnish translation added, Dutch translation
	  updated.
	* FAQ updated.
	* Code cleaned and documented. Linux-like style applied to
	  code source. Large functions split into smaller ones.

2008/01/06: Version 8.0.4 - Sebastien Godard (sysstat <at> orange.fr)
	* Removed a 'packed' attribute in pidstat.h that generated
	  a warning with gcc 4.1.1.
	* Take account of all memory zone types when calculating
	  pgscank, pgscand and pgsteal displayed by sar -B.
	* XML Schema added. Useful with sadf option -x.
