========================================================================


+++ 10. March 2000 +++ ADOL-C Version 1.8.7

  (a) 10. March 2000
      "removed trigraphs usage" from 
         uni5for.c
    	 ho_rev.c
	 SPARSE/int_for.c 
         SPARSE/int_rev.c
      --> no preprocessing phase anymore!! (see makefiles)
      
  (b) 10. March 2000
      better warning messages for discontimuities in forward sweeps
        uni5for.c
	SPARSE/int_for.c

  (c) 10. March 2000
      tested on DEC Alpha using DEC's C++ Copiler cxx
      --> new makefiles in subdirectory INS

  (d) 10. March 2000
      fixed error in DEX/detexam.C

  (e) 28. February 2000
      In files 
        DRIVERS/drivers.h 
        DRIVERS/driversc.c
        DRUVERS/driversf.c
      fixed comment for lagra_hess_vec
      	
     
+++ 14. February 2000 +++ ADOL-C Version 1.8.7

  (a) 14. February 2000
      Now new opcodes for y += x1 * x2; and y -= x1 * x2;
      with recomputation are taken into account;
      Changes in files:  SPARSE/int_for.c
	                 SPARSE/int_rev.c
			 
  (b) 14. February 2000
      fixed bug in SPARSE/jacutils.c according to 
      Andreas Waechter from CMU
      
  (c) 14. February 2000
      New macro USE_CALLOC can be defined (in the file usrparms.h)
      to force ADOL-C allocation routines to use 'calloc' instead
      of 'malloc'. This may help in case of trouble with uninitialized
      memory as reported by Andreas Waechter (on SGI O2). 

  (d) 14. February 2000
      In file SPARSE/jacutils.c:
      The call to zos_forward is now avoided when calling
      jac_pat in save reverse mode, thus no basepoint needs to
      be given as indicated in the documentation.
       
  (e) 07. February 2000
      in File adouble.h: 
      '#include <iostream.h>' instead of '#include <stream.h>'  


+++ 13. December 1999 +++ ADOL-C Version 1.8.5

  Differentiation of LU-Factorization now with O(n^2) saves

  (b) 10. December 1999
      Check and changes in adouble.h + .C concerning the class
      hierarchy
      
  (c) 22. November 1999
      New opcodes for:   y += x1 * x2; and y -= x1 * x2;
      Changes in files:  adouble.h + .C
                         dvlparms.h
			 uni5_for.c
			 fo_rev.c ho_rev.c
			 oplate.h
			 taputil.h taputilc.c
			 tayutil.h tayutilc.c

  (a) 16. August 1999
      File uni5for.c:
      computation of size of valuestack (=taylor buffer) changed
      in order to avoid overflows allowing larger values of vs_size

      !!! unsigned longs or even doubles for counters planed for
          future versions of ADOL-C !!!
  
  (b) 14. July/16. August 1999
      File tayutilc.c:
      performance tuning (get_taylors)

  (c) 15. July 1999

  (a) 10. March 1999 
      All files in directory <ADOLC18_DIR>/SRC/SPARSE

      changed according to (a).

  (c) 09. March 1999
      New example program 'pargearexam' modelling a
      parametrized version of 'gearexam' has been
      added, consisting of the files: 
      <ADOLC18_DIR>/EXA/TIMING/vfunc_pargear.C
      <ADOLC18_DIR>/EXA/TIMING/pargearexam.ctrl
