Version 1.3 of the GNU Scientific Library is now available at,

and from mirrors worldwide -- see

The md5 signatures are,

The GNU Scientific Library (GSL) is a collection of routines for
numerical computing in C.  The NEWS file entry is appended below.

GSL is free software distributed under the GNU General Public

Thanks to all the contributors who reported bugs and suggested

* What is new in gsl-1.3:

** Changed interface for gsl_sf_coupling_6j...(...). The old functions
actually calculated 6j for a permutation of the arguments (that
related to Racah W). This was incorrect and not consistent with
the documentation. The new versions calculate < {a,b,c}, {d,e,f} >,
as stated in the documentation. The old versions are still available
as gsl_sf_coupling_6j_INCORRECT...(...), though they are deprecated
and will be removed at some point in the future.

** Added new functions for computing Em(x)=exp(-x)*Ei(x), the modified
(scaled) form of the exponential integral, gsl_sf_expint_E1_scaled,
gsl_sf_expint_E2_scaled, gsl_sf_expint_Ei_scaled.
** Fixed compilation problems with gcc -ansi and other ANSI compilers.

** Fixed uninitialized memory access in the Niederreiter quasi-random
number generator.

** Fixed the eigenvalue routines to prevent an infinite loop for Inf
or NaN entries in matrix.

** Fixed a bug in the multifit and multiroots allocation routines
which cause them to fail to report some out of memory conditions.

** Fixed a bug in the seeding for the random number generator
gsl_rng_taus2 which affected a small number of seeds.

** Modified the complex householder transforms to avoid division by
zero, which could cause NaNs to be returned by the gsl_eigen_hermv
eigenvalue decomposition.

** The Nelder-Mead simplex algorithm for multidimensional 
minimisation has been added.

** The random number distributions now include the Dirichlet and
Multinomial distributions.

** Added a new function gsl_fcmp for approximate comparison of
floating point numbers using Knuth's algorithm.

** Added new functions gsl_ldexp and gsl_frexp as portable
alternatives to ldexp() and frexp().

** Fixed a bug in gsl_linalg_bidiag_unpack_B which was returning
incorrect results for the superdiagonal.

** Fixed a bug in the acceptance condition for simulated annealing

** Ordinary differential equations can now be solved using a different
absolute error for each component with gsl_odeiv_control_scaled_new().

** Upgraded to libtool-1.4.3
