New description:
New minor version
I'm thinking it may be API or ABI incompatible, but I'm not sure.
{{{
=======
* What is new in gsl-2.2:
** updated gsl_linalg_cholesky_invert to use Level-2 BLAS
and added function gsl_linalg_pcholesky_invert
** added function gsl_linalg_tri_invert for inverting
triangular matrices
** fix GSL_EIGEN_SORT_VAL_{ASC,DESC} for nonsymmetric
eigensystems (Victor Zverovich)
** added complete orthogonal decomposition routines
(gsl_linalg_COD)
** bug fix where median calculation wasn't reset in
gsl_rstat_reset(); added gsl_rstat_quantile_reset() function
(reported by Pedro Donato)
** added multivariate Gaussian random distribution
gsl_ran_multivariate_gaussian (Timothée Flutre)
** added functions to estimate the 1-norm reciprocal condition
number for various matrix factorizations:
* gsl_linalg_cholesky_rcond
* gsl_linalg_QRPT_rcond
** added functions gsl_linalg_QRPT_{lssolve,lssolve2} to
compute least squares solutions with the QRPT decomposition
** added function gsl_permute_matrix()
** added modified Cholesky factorization (gsl_linalg_mcholesky)
to handle symmetric indefinite matrices
** added pivoted Cholesky factorization (gsl_linalg_pcholesky)
for ill-conditioned matrices
** rewrote (real) Cholesky decomposition to use
a Level-2 blas algorithm instead of Level-1. Flop
count is about the same but the code is much simpler
and easier to follow
** completely rewritten nonlinear least squares module,
including support for large problems; the user may
now control the linear solver used, the trust region
updating strategy, and the scaling method. In addition,
support has been added for the geodesic acceleration
step (Transtrum 2011) which can speed up convergence
on a wide class of problems.
** added gsl_rstat_rms() for root mean square
** optimized lmniel nonlinear least squares solver
(bug #46369)
** improved precision in Bessel K0/K1 near x = 2
(Pavel Holoborodko, bug #47401)
** added support for compressed row storage sparse
matrices (Alexis Tantet)
** bug fix in convergence check of hypergeometric 2F1
function (bug #45926)
** added gsl_multilarge_linear_lcurve() to compute
the L-curve for large linear systems
** updated multilarge normal equations method to use
new Cholesky scaling for better numerical stability
** added scaling to Cholesky routines to reduce the
condition number prior to factorization
}}}
{{{
* What is new in gsl-2.2.1:
** reverted gsl_linalg_cholesky_decomp to its previous behavior
so it is backward compatible; new cholesky routine is
gsl_linalg_cholesky_decomp1

Comment (by renodr):
Now 2.2.1
No longer worried about API/ABI breakage.
