CHANGE LOG

1.1.6:  Let lrcalc build a shared library on Cygwin


1.1.6 beta1:  Fixed segmentation fault on Open Solaris (name conflict
	with hash_insert)

        Added quantum and fusion calculations in the README and
	testsuite


1.1.6 beta:  Merged in the schubert code from schmult-1.1.5.tar.gz
        Standard automake/autoconf build system (autoconfiscation)

        Blames for issues with this build system and/or with this beta
	prerelease should go to:

	    Nicolas M. Thiéry <nthiery at users.sf.net>


1.1.5:  Updated the C code so it compiles (mostly) without warnings
        on 64 bit computers.


1.1.4:  Updated the c code so it compiles with newer versions of gcc.
        Also added a "-f rows,cols" option to mult which is similar to
        the -q option, bus uses fusion product notation (large
        partitions in place of the deformation parameter "q" to obtain
        a Z-basis for the quantum ring of Gr(d,n), see section 8 of my
        paper "Quantum cohomology of Grassmannians" for details.)
        A corresponding command "fusion(rows,cols)" was added to the
        maple interface.


1.1.3:  Changed the quantum(rows,cols) function so it works with Maple 7.


1.1.2:  Changed the return type of the internal function lrcoef() to
        long long to make it possible to compute LR coefficients
        greater than 2^32.  (Thanks to Anatol Kirillov for the bug
        report.)


1.1.1:  Fixed a bug in the communication between the maple interface
	and mult.c.


1.1:    Added a "-q rows,cols" option to mult which makes it possible
	to do computations in the quantum cohomology ring of Gr(d,n)
	where d=rows and n=rows+cols.
	The maple interface has new function "quantum(rows,cols)" which
	causes tos to calculate in this ring as well.


1.0.1:	Fixed error which made the program lrcoef produce false results
        in certain cases.  (Thanks to Alexander Yong for the bug
        report.)


1.0:    First version released.
