The NEWS file entry is appended below. The project home page is at http://www.gnu.org/software/gsl/ Please report any bugs to bug-gsl@gnu.org.

Thanks to all the contributors who reported bugs and suggested improvements. ------------------------- * 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
