Version 1.14 of the GNU Scientific Library (GSL) is now available.
GSL provides a large collection of routines for numerical computing
This is a maintenance release which fixes reported bugs. Support for
multisets and fixed order Gauss-Legendre integration has been added
and the build system has also been upgraded to the latest automake,
autoconf and libtool. The full NEWS file entry is appended below.
The file details are:

Thanks to everyone who reported bugs and contributed improvements.
* What is new in gsl-1.14:
** Upgraded to latest libtool, autoconf and automake (libtool-2.2.6b,
autoconf-2.65, automake-1.11.1). Fixes security hole in 'make
dist' (see Automake CVE-2009-4029).
** Added support for "multisets", which are similar to permutations
and combinations. A multiset is an array of k integers in the
range 0 to n-1 where each value may occur more than once. Multisets
can be used to iterate over the indices of a k-th order symmetric
tensor in n-space. (Rhys Ulerich)
** Added gsl_integrate_glfixed routines for performing fixed order
(Pavel Holoborodko, Konstantin Holoborodko, Rhys Ulerich)
** In the LMDER multi-dimensional fitting routines, the return code
GSL_ENOPROG is now used instead of GSL_CONTINUE for the case where
10 or more attempts to find a suitable trial step have been made
without success. [bug #25383]
** The confluent hypergeometric function gsl_sf_hyperg_U (a,b,x) has
been extended to support x < 0 for cases not involving
singularities in 1F1(a,b,x). [bug #27859]
** The F-distribution gsl_ran_fdist_pdf now avoids unnecessary
underflow and overflow and handles cases where n > 248. [bug
** The SVD routines now use a scaled version of the implicit QR method
and compute the shift more reliably for values at the limit of
double precision, avoiding potential NaNs. [bug #28767]
** A compile time error is emitted if the configuration stage prevents
the functions gsl_isnan and gsl_finite from being defined.
** Added missing dereference in GSL_VECTOR_COMPLEX when not using
GSL_RANGE_CHECK [bug #28017]
** Improved the range of gsl_sf_hyperg1F1(a,b,x) when a<0,b>0. [bug
** Added macros GSL_MAJOR_VERSION and GSL_MINOR_VERSION in
** Improved gsl_eigen_symmv and gsl_eigen_symm to avoid a potential
infinite loop when the tridiagonalised matrix contains very small
values. [bug #28096]
** Added functions gsl_multifit_linear_usvd and
gsl_multifit_wlinear_usvd for multilinear fitting without
column-scaling of the fit matrix.
