Hanna's author, Marc Andre Funk, left Hermes in Summer 1998.
This file lists changes done by various people since then:

Created version 3.1
  Bug fix in eventlist.c:  Function ha_checkeventlist(...) did not
  check if the event number read from input data was already ahead of
  the event number read from the external event list.  Consequently,
  ha_checkeventlist(...) could read until the end of input data without
  finding a match with data once the external list had fallen behind
  the input data.

Released version 3.0 with major changes in the event handling:
+ (Changes in eventlist.c, main.c)
  Added new parameter burstgood to the routine user_burstinit(...):

    user_burstinit( int runnum, int burstnum,
                    int bursttime, int bursttimemu, int burstgood )

  Hanna calls the user_burstinit(...) routine for each new record it 
  encounters in the input file.  If an event list has been given with
  the --event switch the flag burstgood is set to 1 for records 
  matching an entry in the event list and set to 0 else.
  If no event list is given, burstgood is always equal to 1.
+ Changed behaviour of the event list handling routine
  (ha_checkeventlist in eventlist.c):
  If Hanna detects multiple identical entries (where only the 
  (eventnum,burstnum,runnum) triple is relevant!) in an input event
  list it will abort the run after generating an error message 
  with the position of the multiple entries.
  Added the command line switch --evsloppy to continue running 
  (with the option to generate a warning, depending on the verbosity
  level chosen for the EVLIST module) on multiple entries.
+ Renamed some old backup source files (io.c.sav, cuts.org.c) in a 
  consistent way to io.c.YYYYDDMM, where YYYYDDMM gives the date of the 
  last modification.
+ Added configuration for Alpha OSF1 systems running under version V4.x
  (tested on Freiburg Alpha cluster).
+ Updated HTML information.



01 Dec 1998 kwo 
Released version 2.7 with various fixes by various authors:
- 23 Nov 1998 by Marc Beckmann:
  + fixed a typo in main.c to return the correct error code from 
    user_burstinit in fprintf statement
  + fixed a bug in burst number handling of ha_checkeventlist (eventlist.c)
- by Falk Meissner:
  + fixed a few bugs in cuts.c (unfortunately undocumented)
- by Maurice Bouwhuis:
  + fixed a bug in the handling of --debug command line options in
    ha_getargs (args.c)



09 Sep 1998 kwo (in main.c)
Hanna's AUTO mode for time synchronisation used to judge the mode of
choice based on the run number (< 6000 used effective unix
time). After the run number rollover in 1998, this led to wrong
behaviour on 98 data. I made it look into the Unix time as well to
avoid that.
