			    NEWS for 0.3.0

+ I decided to break the single text file with everything into a more
  friendly archive, even if I'll surely exceed 20kB for the first
  time. The version number will present ``political version
  numbering'' (as opposed to ``chronological or automated version
  numbering''.  So we have `0', a version that's not yet perfect;
  `3', the third mayor attempt to make things better; finally we have
  `0', a release that wants testing.

+ new ioctl CIOGETEV was implemented in the hope it can be used from
  xntpd.  I used a trimmed-down version of Harald Koenig's patch
  (k-dcf.patch-1.3.58).  The time stamps are used for both, the PPS
  routine and the line discipline.

+ implementation of TIOCDCDTIMESTAMP was removed again because of the
  change to serial struct.  Furthermore the new CIOGETEV can do things
  even better (it has an event counter)

+ Much improved testing program (I hope; in fact it's almost
  completely rewritten).  User-visible changes include better error
  reporting and edge detection selectable from command line.

+ Possibly improved pulse generator including emulations for common
  errors (see BUGS).

+ CONFIG_HARD_PPS is CONFIG_PPS_SYNC now (for no very good reason)...

+ Major corrections to the kernel, especially `adjtimex':

    * All parameters are checked now.  Previously several parameters
      were unchecked.

    * It's no longer allowed to change read-only status bits, but
      still no error is returned, because it seems that's how xntpd
      expects things to work (it's easier that way).

    * A plain old `adjtime()' can be done independent of any
      STA_-settings (that's what the memorandum says about
      compatibility with existing applications)

    * Avoided some `if's by grouping checking and setting of values
      together (where it was easy ;-))

    * `adjtimex' now returns an error depending on several status bits
      (e.g. when you enable STA_PPSFREQ when there is no
      STA_PPSSIGNAL)

+ (kernel/sched.c) If the clock's maximum error reached
  NTP_PHASE_LIMIT (16 seconds as per memorandum), the clock is
  declared STA_UNSYNC, and the time state will be TIME_ERROR. The
  specification is not too clear on the latter point.

+ The CMOS clock is now updated if STA_UNSYNC is cleared (and no
  longer if time_state is not TIME_ERROR).

+ The `hardware_pps' (hardpps) routine has two parameters now, the
  timeval and the hardware counter (microtime).  Changed for no good
  reason.  Fixed a bug that required 5 good calibrations before the
  interval was increased (memorandum talks about 4).  

+ Added some comments (at various places), reformatted some lines,
  added debugging code, etc.

+ (arch/i386/kernel/time.c) The code to update the CMOS clock is
  broken!  I was unsure how to fix it, so I added a warning message if
  the code fails.  This has to be fixed soon!

+ (drivers/char/serial.c) The version of the driver has been changed
  by adding a 'a'.  In addition the option `PPS' has been defined for
  CONFIG_PPS_SYNC.  The code to print the startup message has been
  improved (a matter of taste).
