	  new volume fine tuning would not work - fixed

2005-07-15  0.7.0-3
	* change volume control: volume up/down change volume always
	  by 10% (hardware independent), shift + volume up/down change
	  volume by 1 step (hardware dependent).

2005-07-11  0.7.0-2
	* module_cdrom can't find the mountpoint if the link to the device
	  is a relative link - fixed.
	* readlink buffer not correctly terminated - fixed.

2005-07-10  0.7.0-1

2005-07-01  0.7.0beta2   (public bets)
	* check for ADB keyboard and trackpad added. Configuration of
	  the trackpad and/or keyboard is now restricted to PowerBooks
	  which have an ADB trackpad and/or ADB keyboard.
	* Trackpad tap will be disabled at first key press and enabled
	  again at first mouse movement. No changes inbetween. This
	  reduces ADB messages significantly.
	* spanish language file updated. Thanks to Rudy Godoy
	  <rudy@kernel-panik.org>
	* pbbcmd man page updated

2005-06-26  0.7.0beta1   (public beta)

	  correctly. Furthermore the maximun count of input
	  devices has been increased.

2005-06-19  0.6.10-4
	* the mountpoint is found in both directions now.
	  For example: dev_cdrom = /dev/cdrom
 	               /dev/cdrom is a link to /dev/hdc
	               /dev/hdc is mounted
	  or
	               dev_cdrom = /dev/hdc
	               /dev/cdrom is a link to /dev/hdc
	               /dev/cdrom is mounted

2005-06-18  0.6.10-3
	* If the configured CDROM device is a link to another
	  device and the CDROM is mounted trough this other
	  device, pbbuttonsd couldn't eject the CDROM.
	  This is fixed now because both devices are checked.
	* typo's in german language file corrected, thanks
	  to Jens Seidel <jensseidel@users.sf.net> for his
	  patch.

2005-06-17  0.6.10-2

2005-05-23  0.6.9-5  (public beta)
	* some code and documentation cleanup

2005-05-21  0.6.9-4
	* filter BTN_LEFT as key event because it breaks
	  'NoTapTyping'. Problem with trackpad fixed.

2005-05-20  0.6.9-3  (public beta)
	* Tags TAG_MOUSEBUTTONS and TAG_MOUSEWHEEL removed
	* scan_for_kdbdevs() replaced by scanEventDevices()
	  which will scan for all event devices, not only for
	  keyboards.
	* New event input handler replacing the special input
	  handlers for mouse and keyboard.
	* input handler return an error code now. If the input
	  handler belong to an event device, this device will
	  be disabled and scanEventDevices () is called.
	  If the input handler belong to any other source, the
	  daemon will quit due to a FATAL error.
	* evdev kernel module is no longer loaded if missing.
	  The system must be set up accordingly before starting
	  the daemon.

2005-04-27  0.6.9-2
	* a pseudo keycode will be emitted if an power button
	  interrupt is received. This is important for new
	  aluminum powerbooks until the kernel supports the
	  power button natively.

2005-04-13  0.6.9-1
	* some error messages in module_alsamixer added
	* E_NOSUPPORT won't exit the program anymore

2005-04-06  0.6.9   (public release)

2005-04-05  0.6.8-3
	* explain keycodes in man-page.
	  This closed debian bug #280211

2005-04-04  0.6.8-2
	* pmcs script bdflush logs a message if an external
	  laptop-mode script is active.
	* errors during program initialisation didn't lead to program
	  abortion - fixed
	* error messages uses more syslog levels for reporting (LOG_ERR,
	  LOG_WARNING and LOG_INFO) instead of using only LOG_ERR.
	* Even if started as daemon error messages will be printed to
	  stderr as long as the parent process recognises them. Warnings
	  and info messages will be redirected into syslog as soon as
	  the \'-d\' is detected in the command line arguments. 
	  This closes debian bug #188317
	* language files updated

2005-04-01  0.6.8-1
	* TAG_CLIENTPID added. The server recorded the client pid for
	  internal use. Recommendation: Recompile all clients.
	* trackpad configurations has been downgraded from secure to
	  normal function.
	* trackpad reconfiguration takes also place now when a key is
	  constantly pressed (key repeatition function)
	* trackpad disable time decreased to 600 ms again.
	* script bdflush updated so that it look for a global laptop-
	  mode script first before using the private one. This script
	  is depreciated now and might be removed in future releases
	  including the local copy of laptopmode.sh.
	  This closes debian bug #290766
	* a native pbbuttonsd script for laptop-mode-tools has been
	  sent to the package maintainer of laptop-mode-tools.
	  It will enter pbbuttonsd's CVS but never become part of
	  a distribution package.
	* added current directory to PATH in pmcs-pbbuttonsd to make it
	  work with other shells than bash too. Thanks to Jörg Sommer
	  <joerg@alea.gnuu.de> for his patch.
	  This closes debian bug #295178.

2005-03-24  0.6.8   (public release)
	* keyboard scanner tested for EV_REP but some new button
	  devices haven't this flag set and therefore aren't detected.
	  To exclude pointing devices the keyboard scanner tests now
	  for EV_KEY && !EV_REL to detect keyboards.

2005-03-22  0.6.7-9
	* client list extended with name and flags. If a client wants to
	  register it must provide a name and optional additional flags.

	  ! Please pay attention to the changed ipc_init() interface. !
	  ! Clients linked with an old libpbb will work as usual but  !
	  ! you should move to the extended interface with your next  !
	  ! release. Future extensions will depend on the extra data. !

	* libpbb IPC: servertags evaluation moved behind taglist processing.
	  This has the advantage that strings in taglists provided with
	  server action like register and unregister clients would be 
	  correctly relocated.
	* trackpad enable (notap) time increased to 0.8 seconds
	* registerflags CLIENT_EXCLUSIVE and CLIENT_REPLACEMENT added.
	  With CLIENT_EXCLUSIVE only one client instance is allowed.
	  Additional registrations will be rejected.
	  With CLIENT_REPLACEMENT only one client instance is allowed too,
	  but this time the existing instance will be closed and replaced
	  by the new one.

2005-03-21  0.6.7-8
	* list code moved to libpbb
	* static client array replaced by dynamic client list. Client count
	  isn't limited anymore.
	* documentation updated

2005-03-20  0.6.7-7
	* returned channels from ossmixer were filtered by supported channels
	  which leads to wrong channels if the mixer module is not active.
	  Solution: Mixer will always return user setting now even the mixer
	            doesn't support the named channels.
	* automatic mixer detection fail if only one or no mixer module is
	  compiled in - fixed
	* language files updated

2005-03-19  0.6.8beta1   (public beta)

2005-03-17  0.6.7-6
	* improved error reporting in various modules
	* error in open functions of alsamixer and ossmixer - fixed
	* Following depreciated tags have been removed and won't be
	  supported any longer: TAG_ONACPOLICY, TAG_ONACSLEEP,
	  TAG_ONACCOVERSLEEP, TAG_ONACTIMESLEEP, TAG_ONACTIMEDIM,
	  TAG_ONBATTERYPOLICY, TAG_ONBATTERYSLEEP, TAG_ONACDIM,
	  TAG_ONBATTERYCOVERSLEEP, TAG_ONBATTERYTIMESLEEP,
	  TAG_ONBATTERYTIMEDIM, TAG_ONBATTERYTIMEHDOFF, TAG_ONBATTERYDIM,
	  TAG_ONBATTERYBLANK, TAG_ONACTIMEHDOFF, TAG_ONACBLANK,
	  TAG_SCRIPTBATCRITICAL, TAG_SCRIPTPROFCHANGED, TAG_SCRIPTHDSETUP,

	  ! If you use this tags in your program please change !
	  ! it and use the appropriate replacement tags.       !

	* added soundsystem autodetection code

2005-03-16  0.6.7-5
	* all modules adapted to the config manager. Old configfile
	  mechanism removed.
	* obsolete configuration file options removed. Old configuration
	  files can't be used anymore.
	* new configuration options for ALSA and OSS specific options.
	
	  ! Please update your configuration file to the new options. !
	  ! Some OSS related options have been renamed.               !
	  
	* changed module initialization sequence: init - open - configure.
	* the mixer modules keep module specific configration options even
	  the module is not active. This removes a bug from the BUGS file.
	* error reporting of module_cdrom improved
	* new command line option --quiet to suppress the welcome message
	* made trackpad reconfiguration while typing configurable. The
	  tag TAG_NOTAPTYPING controls this feature.

2005-03-13  0.6.7-4
	* introduce new config manager as replacement for configfile
	* dynamic handling of configuration options. Options will be
	  registered by the modules now.

2005-03-06  0.6.7-3
	* LMU device detection code returns wrong device number if
	  it is below 4 - fixed. Thanks to Mark Ferry <gnomeza@imap.cc>
	* trackpad reconfigured to 'notap' while typing (feature request
	  from debian powerpc mailinglist). Mode will be restored 0.6
	  seconds after last key stroke. Function is not configurable yet.
	* trackpad mode has been lost after sleep - fixed

2005-02-05  0.6.7-2
	* file descriptor leak in module_display - fixed. Thanks to
	  Andreas Schwab <schwab@suse.de> for his patch.

	  correctly - fixed.

2004-12-12  0.6.6-6
	* add soundsystem flags to TAG_SYSINFO
	* added query for the currently active soundsystem
	* added tag TAG_SOUNDSYSTEM to query active soundsystem
	* added tag TAG_SOUNDSYSTEMCFG to configure soundsystem. This
	  configuration becomes active only after saving the configuration
	  and restarting the server.

2004-12-10  0.6.6-5
	* module_display checks current level of LCD brightness now before
	  modifying it and keeps it synchron. This compensate brightness
	  changes from other tools than pbbuttonsd.

2004-11-28  0.6.6-4
	* function print_error in libpbb become UTF-8 safe. Error texts
	  will be converted to local charset before printing to terminal
	  or to logfile. Iconv must be available for this to work.
	* new spanish translation, thanks to Rudy Godoy
	  <rudy@kernel-panik.org>

2004-11-25  0.6.6-3
	* added m3mirror functionallity for ATI Rage128 and Radeon
	  cards. It will support all cards the frambuffer supports.
	  a new keycode was added to the display module to switch
	  the external display on/off.

2004-11-21  0.6.6-2

2004-11-04  0.6.6   (public release)

2004-10-25  0.6.5-4
	* Powerbook G3 lombard's PMU doesn't report the AC power flag in
 	  environment flags. Program changed to use /proc instead.

2004-09-24  0.6.5-3
	* start LMU device detection now with /dev/i2c-4 to avoid errornous
	  detection of device /dev/i2c-0. The devices 0 to 3 will be tested
	  last.

2004-09-23  0.6.5-2
	* separate getting power source from reading battery info.
	  pmac_update_flags() falls automatically back to /proc/pmu/info if
	  the pmu driver reports an error via ioctl.

2004-09-20  0.6.5-1
	* fix bug in pmac_timer. cover and power source weren't updated
	  correctly after sleep.

2004-09-10  0.6.5   (public release)

2004-09-09  0.6.4-6
	* without backlight controller the bahaviour of the display
	  module changed as follows:
	  - LCD brightness only changes between 0 and MAX
	  - clients will always get -1 as LCD brightness level
	    This change recommends installation af latest clients
	  - the framebuffer would be switched off before suspend-to-RAM
	    if configured accordingly (mostly doesn't work)
	  - display dimming, if activated, will switch the display
	    off, if UseFBBlank=yes. (ATTENTION: Backlight might keep
	    alit, check carefully before using display dimming this way)
	  ATTENTION: Read file BUGS for more details.

2004-09-08  0.6.4-5
	* The function getting the backlight level from the hardware
	  checks now for errors. The new return value -1 indicates
	  that no backlight controller is available.

	* add TAG_TAG_ONAC_POLICY, TAG_ONAC_TIMERACTION, TAG_ONAC_COVERACTION,
	  TAG_ONAC_KEYACTION, TAG_ONAC_TIMESUSPEND, TAG_ONAC_TIMEDIM,
	  TAG_ONBATT_POLICY, TAG_ONBATT_TIMERACTION, TAG_ONBATT_COVERACTION,
	  TAG_ONBATT_KEYACTION, TAG_ONBATT_TIMESUSPEND and TAG_ONBATT_TIMEDIM
	  This tags now support suspend-to-disk.
	* mark TAG_ONACSLEEP, TAG_ONACDIM, TAG_ONACTIMESLEEP, TAG_ONACTIMEDIM,
	  TAG_ONACCOVERSLEEP, TAG_ONACPOLICY, TAG_ONBATTERYSLEEP,
	  TAG_ONBATTERYDIM, TAG_ONBATTERYTIMESLEEP, TAG_ONBATTERYTIMEDIM,
	  TAG_ONBATTERYCOVERSLEEP, TAG_ONBATTERYPOLICY and TAG_SLEEPKEYSLEEP
	  as depreciated. Don't use them in your code. Use the replacements
	  instead.

	  of module_pmac.c

2004-08-07  0.6.3-5
	* keyboard illumination behaviour in conjunction with on/off key
	  changed. If not in autoadjustment mode an initial brightness
	  could now be defined with TAG_KBDONBRIGHTNESS. Thanks to
	  Rodolfo Giometti <giometti@linux.it> for his patch.

2004-08-06  0.6.3-4
	* new Tags TAG_BATLOG and TAG_BATCYCLE added. This control battery
	  data logging during runtime. The compile time options --with-batlog
	  and --with-batcycle have been removed. (closes debian bug #262544)
	  Attention: The meaning of the Tags are not exactly the same as the
	             compile time options. Read the man-page for details.

2004-08-03  0.6.3-3
	* pbbcmd: added version to help text
	* pbbcmd: removed private tags from help list
	* pbbcmd: added parameter 'i' to force pbbcmd not to wait for
	  servers answer after sending config commands.
	* pbbcmd: man-page updated
	* pbbcmd: decrease timeout time from 10 to 4 seconds

2004-07-30  0.6.3-2
	* improved test for running deamon implemented. It detects now
	  dead message ports and removes them at startup. With this 
	  Pbbuttonsd is able to cope with kill -9 wihout users help. 

2004-07 29  0.6.3-1
	* ac status in /proc/pmu/info is not reliable if no battery is
	  pluged in. So from now on pbbuttons asks the PMU directly.

2004-07-22  0.6.3a (public release)
	* add script tags 'cover-open' and 'cover-close'
	* two spelling mistakes corrected in pbbuttonsd.conf
	* one spelling mistake corrected in configfile.c

2004-07-19  0.6.3  (public release)
	* fix a type in script bdflush

2004-07-17  0.6.2-4
	* exit commands removed from scripts so that the exit codes of
	  the subscripts survive.
	* The script child set his own process group so that it and all
	  it's child could easily be terminated on error or timeout.
	* change the supervising code to send the SIGKILL not only to the
	  pmcs-script child but to all childs of the same process group.
	  Unfortunately this will only work in full with a patched 
	  run-parts version where all parts share the same process id.
	  Debians run-parts creates a new process id with each running
	  part so that this processes will remain in memory on error or
	  timeout. A bug-report has been filed to debian.

2004-07-16  0.6.2-3
	* some calls of open() especially in module_ossmixer didn't
	  accept 0 as valid file handler. Due to this the mixer device
	  may remain open after usage. After a suspend event the ALSA
	  scrips stop all processes that uses sound devices including
	  pbbuttonsd. This bug was fixed now. 
	* module_powersave uses depreciated tags - cleaned up
	* old config options removed from configfile.c
	* launch_program() did't check for fork() and waitpid() error codes.
	  A fork() failure might caused weird system reactions - fixed.
	* call_script() translates new error codes in human readable text.
	* the PMCS script 'bdflush' will only work for kernel 2.4. It was
	  replaced by a more general one that now calls 'laptop_mode.sh'
	  from the kernel tree.

2004-07-01  0.6.2-2  (version lost)

2004-06-30  0.6.2-1  (version lost)

2004-06-21  0.6.2  (public release)

2004-06-19  0.6.1-1
	* Automatic keyboard brightness adjustment work against
	  manual control due to bug in keyboard handler - fixed.
	* keyboard illumination can't be switched off completly.
	  Copy & paste error from LCD code - fixed
	* Toggle keyboard illumination on/off increased the level
	  by one each time. Collision with autoadjustment code
	  - distangled.
	* added keycodes für special keyboard illumination keys
	  from the kernel patch from Andreas Jaggi.

2004-05-26  0.6.1   (public release)
	* cleanup modules could be skipped if signal handler
	  setting failed - fixed
	* obsolete function detach_process() removed from
	  libpbbipc.
	* bug in daemonize and ipc code of libpbbipc fixed.
	  This bug could block message queue cleanup if an
	  error occured during program initialization. Altough
	  the daemon isn't running, this leads to the error
	  message "pbbuttonsd already running, only one
	  instance allowed".

2004-05-22  0.6.0-3
	* /proc/cpufreq interface for kernel 2.4 missing in
	  scripts.d/cpufreq - added. Thanks to Wolfgang Pfeifer
	  <roto@gmx.net>

	  shutdown now.

2004-05-19  0.6.0-2
	* Blanking the screen comming from dimmed display causes
	  the original brightness value to be lost (debian
	  bug #249782)- fixed.

2004-05-12  0.6.0-1

	* New Script system introduced. Debian bug #249501 solved.

2004-04-29  0.5.11-6
	* call PMCS script to set power policy after wakeup if
	  power source has changed.
	* call PMCS script to set power policy after TAG_REINIT.
	* script PMac_G3 not longer necessary with 2.4 and 2.6
	  kernels - removed

2004-04-26  0.5.11-5
	* directories in scripts renamed: active->event.d and
	  storage->scripts.d.
	* some arguments of the pmcs script renamed: sleep->suspend
	  and wakeup->resume. All scripts modified accordingly.
	* script apmd_compat added. Thanks to Guido Guenther
	  <agx@debian.org>.
	* added support for additional directories suspend.d and
	  resume.d if existing.

2004-04-23  0.5.11-4
	* man-pages updated
	* obsolete code fragments removed
	* TAG_REINIT added to restore hardware setting for example
	  lost due to suspend to disc. This action could also
	  triggered with
	  SIGUSR1.
	* code cleanup in install_sighandler()
	* code cleanup in pbbuttonsd.c
	* changed script config variables to policy dependent names.

2004-04-21  0.5.11-3
	* add TAG_ONACPOLICY and TAG_ONBATTERYPOLICY
	* add onAC_policy and onBattery_policy to configfile
	* make options with discrete arguments like tpmode,
	  emergencyaction etc more robust against invalid values.
	* code cleanup in configfile.c
	* replace some #defines against enum{} in module_pmac.h and
	  module_powersave.h. This simplifies code and improve error
	  robustness.
	* added TAG_BRIGHTNESS again for compatibility reasons. Please
	  be aware that this tag is DEPRECIATED and will be removed in
	  future. Use TAG_LCDBRIGHTNESS instead.
	* add TAG_POLICY to set the current power policy.
	* TAG_SCRIPTHDSETUP, TAG_ONACHDTOFF and TAG_ONBATTERYHDTOFF
	  removed. Hard disc setup will be done in pmcs script now.
	* TAG_SCRIPTBATCRITICAL removed. This job is also done by
	  pmcs script now (first argument=emergency).
	* TAG_SCRIPTPROFCHANGED renamed in TAG_SCRIPTPMCS.
	* changed all script calls of script_profchanged, script_hdsetup
	  and script_batcritical to script_pmcs.
	* pmcs-* scripts need a 'cd' to the target directory because
	  all paths in the scripts are relative paths.
	* add example script named skeleton
	* describe script parameters in a README instead of inside each
	  script header.
	* german translations updated
	* script path in pbbuttonsd.conf will now be adjusted by the
	  configure script.

2004-04-20  0.5.11-2
	* added missing variable for xgettext and fixed a bug in 
	  POTFILES.in
	* change main Makefile.am to handle new structure in scripts/
	* introduce new pbbuttonsd script system
	* setting Tdim=0 will disable display dimming now. Therefore
	  TAG_ONACDIM, TAG_ONBATTERYDIM and its corresponding config
	  options onAC_dim and onBattery_dim were useless and have
	  been removed.
	* setting Tsleep=0 will disable sleep when idle now. This
	  feature is new.
	* The command GOTOSLEEP will always trigger sleep now, if
	  possible. If sleep was not supported by the hardware the
	  screen will be blanked instead. No configuration possible.
	* use sig_atomic_t datatype now instead of int for global
	  variables used by the signal handler.

2004-04-19  0.5.11-1
	* development version with special debugging output.

2004-04-18  0.5.11   (public release)

2004-04-17  0.5.10-4
	* module_powersave.c: TAG_POWERCHANGED called power_awake to
	  reset the sleeptime counter. This has bad side effects so
	  that the sleeptime counter is reseted directly in
	  power_handle_tags(). As result the mode (dim or sleep) will
	  not change on switching the power source.
	* module_powersave.c: Keeps track of cover status now and
	  disables keyboard and mouse input if cover is closed. This
	  was a problem with external mice and keyboards in
	  conjunction with screen blanking on sleep request (debian
	  bug #249783).
	* module_display.c: Keeps track of cover status now and
	  disables keyboard input if cover is closed.
	* libpbbipc: cleanup_buffer() handles quoting incorrectly
	  - fixed.

2004-04-16  0.5.10-3
	* added catalan catalog file. Thanks to David Riera
	  <driera@infoblitz.com> and Oriol Pellicer <oriol@elsud.org>

2004-04-05  0.5.10-1
	* not initialized variable flags.status in module_display - fixed.
	* eject CDROM uses the mountpoint now instead of the device.
	  This leads to less trouble ejecting mounted CDs. Thanks to
	  Soeren Sonnenburg <bugreports@nn7.de>

2004-03-31  0.5.10  (public release)

2004-03-30  0.5.9-5

	* increase interval for ambient update timer in display
	  module to 1 second.
	* option HeartbeatBeep set to 'no' by default. Make the

	* restructured configuration options for display module
	* beautify saved config file
	* default config file updated
	* configuration man-page updated
	* scale of the ambient sensor changed to percent.
	* eject CD event sends now a signal to all clients. This
	  signal is also sent, if eject has failed due to umount().
	  This will be fixed in the future.
	* with configure option --with-pmud the linker can't find
	  pmac_cover_position() - fixed.
	* modified equations for automatically calculated brightness
	  levels so that the user keeps in control. An offset shifts

	* bug in scan_kbddevices() fixed. keyboards are correctly
	  unregistered now.
	* support generic i386 laptops without laptop dependent

2003-12-27  0.5.7-1
	* After wake up with closed cover the machine didn't go
	  to sleep again - fixed. This happens for example when USB
	  devices are connected/disconnected during sleep.

2003-12-19  0.5.7  (public release)

2003-12-11  0.5.6-4

	  from configfile - fixed
	* timeout for scripts was to short - extended to four
	  seconds.
	* scan_for_kbdevdevs() did't close all file
	  handles - fixed.

2003-11-17  0.5.6-2
	* module_pmac.c reads flags from /proc/pmu/battery_%
	  as decimal instead of hexadecimal. This could lead
	  to wrong charging detection - fixed.

2003-11-13  0.5.6-1
	* configure flag --with-pmud added to decide
	  at compile time to use pmud or not.

	* TAG_ONACCOVERSLEEP and TAG_ONBATTERYCOVERSLEEP
	  added to make behaviour after cover closed
	  independently configurable.
	* TAG_ONACBLANK and TAG_ONBATTERYBLANK removed.
	* play a beep every 30 seconds when the screen is
	  dark so the user knows the machine is still alive.

2003-09-24  0.5.4b
	* processing the configuration at startup launches some
	  empty scripts - fixed
	* launching the power changed script at startup broken
	  - fixed.

	* package pbbcmd integrated in pbbuttonsd. Pbbcmd makes
	  no sense as independent package.
	* config.h missing in some sourcefiles - fixed
	* problems with translating comment for configfile - fixed

2003-09-10  0.5.3g
	* after awake from sleep some data in module_poversave
	  wasn't immediately updated. It operates up to 100ms
	  with old data. This could have caused different strange
	  behaviour like shutdown or sleep immediately after
	  the machine has awaken or shutdown after last disentangled
	  warning even though the AC connector has been plugged
	  in recently (debian bug #183614) - fixed.
	* script arguments for SCRIPT_PROFCHANGED changed:
	  the arguments 'ac' and 'battery' were replaced by
	  'profile'. A second argument containing the powersource
 	  was added.
	* TAG_TIMEREMAINING and TAG_POWERSOURCE disentangled,
	  because config and query operations with this tags were
	  done by two different modules, which causes responsibility
	  problems. To keep compatibility to existing clients,
	  the tag values weren't changed. But this have to be done
	  in an later restructuring of the interfaces.

2003-09-09  0.5.3f
	* mark TAG_BRIGHTNESSOP and TAG_COVERSTATUS as private

	* some code cleanup in module pmac(1 to go)
	* some code cleanup in module poversave ( done  )
	* preventing TAG_TIMEREMAINING from sending if AC power
	  is connected. In conjunction with changing default
	  low battery emergency behaviour the 'laptop halted'
	  problem (debian bug #183614) should be solved.

2003-09-08  0.5.3e
	* empty strings in configfile causes segfault - fixed.
	* typo in framebuffer device default setting - fixed
	* configfile could be saved now (/var/lib/pbbuttons/).

2003-09-07  0.5.3d
	* some code restructuring in input manager. moved some code
	  from pbbuttonsd.c to input_manager.c to make custom
	  input managers possible.
	* moved the timer code from pbbuttonsd.c to input_manager.c
	* some general code cleanup
	* work around for kernel problem: booting without batteries
	  connected in module_pmac.c#pmac_update_batteryinfo()
 	  implemented.

2003-09-06  0.5.3c
	* bug in warning level calculation makes it impossible
	  to step a warninglevel up again - fixed.
	* powerwait and powerokwait implemented. SIGPWR to the
	  init process works.
	* IPC signals routed through the module_peep for debugging
	  This is only active if compiled with DEBUG.
	* TAG_IDENTITY added. The identity string is printed to
	  console at pbbuttonsd startup.
	* The profile-changed-script and HDSetup-script will now
	  be started at pbbuttonsd startup to do initial settings.
	* removed default settings for script_batcritical. Default
	  emergency behaviour is now sleep. No shutdown anymore
	  unless it's explicit configured.
	* scripts were now checked for permissions and owner to
	  improve security.

2003-09-05  0.5.3b
	* TAG_ONBATTERYCRITICALSLEEP removed and replaced by
	  TAG_EMERGENCYACTION with four commands: EMA_SLEEP,
	  EMA_SIGNAL and EMA_COMMAND.
	* Signal to INIT process integrated. It uses first the new
	  method via /dev/initctl and second if that failed the old
	  method via /etc/powerstatus.
	* Module_peep writes a battery profile in
	  /var/lib/pbbuttons/xxx_battery.log. This is only active
	  if compiled with DEBUG.

2003-09-04  0.5.3a
	* ToDo List updated
	* Changed to new Version of autoconf/automake. The header
	  acconfig.h was removed

2003-04-13  0.5.3a
	* The CDROM device could be missing now. The check at
	  startup has been adjusted.

2003-03-16  0.5.3
	* sleepkeydelay works again
	* sleepkeydelay and ejectcdkeydelay changed to use
	  time periods in milliseconds instead of counting
	  repeating keys. (debian bug #164882).
	* typo in option EjectCDKeyDelay in configfile - fixed
	  (debian bug #184323)
	* option MixerChannels added to control which channels
	  should be controlled by the volume keys (debian bug
	  #176000).
	* pbbuttonsd failed if the mixer device didn't exist
	  even if mixer_delayed was set. This problem occurred
	  with devfs. Now, if mixer_delayed was set, a missing
	  mixer device wouldn't cause an error messages or
	  hinder pbbuttonsd to startup (debian bug #182218).
	* EjectCDKey in default config file set again to 161.
	  This is the correct value for iBooks.
	* option 'userallowed' added to imrove security of the
	  ipc-interface (debian bug #164881). First step done.
	  maybe further steps will follow.

2002-12-22  0.5.2b
	* config file option 'replace_pmud' did nothing, fixed.

2002-10-13  0.5.2a

	  the effective process owner of pbbuttonsd.

2002-07-03  0.5.0p
	* pmac: fixed cover status and OHARE button level
	  evaluation.

	  done instead.
	* SIGHUP implemented.
	* config table in read_configfile() set to static due
	  to a segfault on receiving SIGHUP.

2002-03-17  0.4.4
	* If the machine is idle first the display will be
	  dimmed and after some additional idle time it will
	  go to sleep
	* add command line switch '-n (nosleep)' to disable
	  the dim/sleep feature on user demand.

2002-03-15  0.4.3
	* add the command line switch '-e' which causes that

	  this should work on every supported machine.

2002-03-07  0.4.2a
	* fixed a problem with the exit code.
	* fixed serious bug that caused a segfault when the
	  program exited (Thanks to Geof)

	* The server was put to a separate package.
	* removed package name from package data directory
	* adapt some texts to the new package name
	* update the documentation
	* open mixer device only if needed. Calculate
	  hardware independent volume values by myself.

------------------------------------------------------------------------

2002-03-03
	* Server calculates battery warnlevels and sends
	  alarm messages to clients.
	* little sequencing problem with detach option in
	  client and server fixed.
	* Client displays battery warnings now.
	* Client got the option to play a sound during volume
	  adjustment or play alarm sound at battery warnings.

2002-02-28  0.4.1
	* Server sends exit-message to clients, when it exits.
	* Client exited, if it receives the exit-message.
	* Server polls the pmu and collects data about the
	  cover, the states of the batteries, the volume and
	  brightness buttons and pmu version. Pollcycle was
	  reduced from 100ms to 10ms.

2002-02-26  0.4
	* package divided into client and server. The server
	  could run as root and the client could run as user.
	  The communication is done via SystemV IPC messages.
	* low level IPC functions were exported to a static
	  library.
	* the directory structure was reorganized
	* newly created and updated man pages for client and
	  server

2002-02-22  0.3.3
	* mixer code reworked to fix some problems with newer
	  PowerMac sound hardware, especially iBook2 and new
	  TiBooks.
	* changed lockfile name to a more conventional one.
	* backlight control adapted to new kernel features.
	  Since 2.4.18-rc2-benh the PPC branch of the kernel
	  allow backlight control trough user space programs.
	  In this context the default keycodes for brightness
	  control changed to new kernel defined values. Thanks
	  to Ben Herrenschmidt <benh@kernel.crashing.org>

2002-02-21  0.3.2
	* changed mixer code for verification trough beta
	  testers.

2002-02-20  0.3.1
	* added new comand line switch 'd --detach', so
	  PBButtons could be started now as background
	  process.
	* running PBButtons as daemon causes high CPU time
	  consuming - fixed. Thanks to Uwe Steinmann
	  <steinm@majestix.fernuni-hagen.de>.
	* PBButtons now would use alternative PMU and Mixer
	  devices, if specified. exchanged hard wired device
	  names with dynamic ones.
	* fixed some problems, if compiled with optimization
	  switched on.

2002-02-18  0.3
	* added I18N support with GNU gettext
	* added setup-script to check and setup used devices
	  and directories with suitable user permissions.

2002-02-16  0.2.1
	* PBButtons works now with ALSA 0.9.x via OSS
	  emulation. The mixer device must not to be closed
	  after each adjustment. If so the ALSA OSS-emu mixer
	  would forget the device independent volume levels.
	  The mixer device will now be kept open while the
	  program is running.

2002-02-14  0.2
	* program take care about multiply instances.
	* defined exit procedure via sighandlers.
