Changes in Version 1.0
======================

        1)  Added support for parallel execution of the global model (single 
            population) using MPI (Message Passing Interface).

        2)  Added support for a restart operator.  The best string is used
            to reinitialize the population.

	3)  Added support for new native data type Character.

        4)  Added support to specify the multiplier of the worst evaluation 
            value when remapping a minimization problem.

        5)  Separated specification of mutation type from rate.

        6)  Added new integer mutation operators.

        7)  Added an option to maintain integer and real allele values within
            the range specified on initialization after mutation.

	8)  The configure script argument -optimize has been removed and
            replaced with the -debug switch for compiling a debug version.
            An optimized version of PGAPack is now built by default.

	9)  The configure script argument -arch AIX has been replaced with
            -arch rs6000.

        10)  The configure script now accepts the -cflags and -flags switchs to
            supply supply options to the C and FORTRAN compiler, respectively.

	11)  Changed PGATRUE and PGAFALSE to PGA_TRUE and PGA_FALSE.

	12) Renamed debug macros to begin with PGA_DEBUG instead of PGADEBUG.

	13) Renamed report macros to begin with PGA_REPORT (instead of, for
            example PGA_ONLINE).

	14) Removed macro PGAERROR from pgapack.h.

	15) Rewrote PGARandomInterval(ctx, L, U) so that it would not
	    return L-1.  It now returns [L, U].

	16) PGADone, PGAUpdateGenertaion and PGAEvaluate all take an MPI
	    communicator as the last argument.  See PGARunGM in parallel.c
	    for details on how to rewrite a user run routine.

	17) Removed "Time" from the output.

	18) Shortened the names of the source files as follows:

		character.c                  char.c
		crossover.c                  cross.c
		duplicate.c                  duplcate.c
		f2c_interface.c              f2c.c

	19) Shortened the name of the examples files as follows:

		maxbit_custom.c              maxbitc.c
		maxbit_menu.c                maxbitm.c
		maxint_custom.c              maxbitc.c
		rastrigin.c                  rstrgnb.c
		real_rastrigin.c             rstrgnr.c
		udt_struct.c                 udtstr.c
		udt_struct_array.c           udtastr.c

	20) Replaced the function names on the left with the function	
	    names on the right.  The Perl script ./util/upgrade_script.pl
            may be of use in automating part of the renaming process on
            exisiting files.

Changes in Version 0.2b
=======================

        1) In PGABinaryTwoPointCrossover, add<ed a test before left-shifting.
           The right operand of a shift must be strictly less than the number
           of bits in the left operand, otherwise the result is undefined.

        2) In udt_char.c, changed the data type to signed char since whether
           char is signed is implementation dependent.

        3) In real_rastrigin, made upper and lower to be dynamic arrays rather
           than static arrays to allow variable string length.


Changes in Version 0.2a
=======================

        1) Created pgapack-0.2.a.tar.Z to replace pgapack-0.2.tar.Z
           when we found the IRIX's do not have a ranlib (unless it
           is in /usr/local.

        2) Deleted a space from ./examples/c/Makefile.in

        3) Added the -w flag to FFLAGS for the freebsd version to
           suppress warnings.


Changes in Version 0.2
======================

	1) In PGASetUp, we changed the default value for the number of
           individuals to replace each generation from 10 to 10% of the
           population size.

        2) Took all the parallel stuff out.

        3) Defined PGAPrintReport and put various PGAPrint functions in 
           the new file system.c

        5) Changed EvalUpToDate to all lower case.

        6) Changed PGARunMutateOnlyNoCross to take PGA_OLDPOP and PGA_NEWPOP
           as arguments

        7) Changed the low-level ops functions to take p,pop as arguments
           instead of a void pointer

        8) Changed PGAMutate to a 3-argument function.  It just mutates,
           but does not copy the string to its final location.  Use
            PGACopyIndividual for that.
