** added new module for digital filtering (gsl_filter); current filters include:
     Gaussian filter
     median filter
     recursive median filter
     impulse detection filter

** added new module for moving window statistics (gsl_movstat)

** added statistics functions:
     gsl_stats_median()
     gsl_stats_select()
     gsl_stats_mad()
     gsl_stats_mad0()
     gsl_stats_Sn_from_sorted_data()
     gsl_stats_Qn_from_sorted_data()
     gsl_stats_gastwirth_from_sorted_data()
     gsl_stats_trmean_from_sorted_data()

** added Romberg integration (gsl_integration_romberg)

** bug fix in deprecated functions gsl_multifit_wlinear_svd and
   gsl_multifit_wlinear_usvd (reported by Vlad Koli)

** documentation corrected to state that gsl_sf_legendre functions do
   not include Condon-Shortley phase by default

** bug fix in exponential fitting example when using larger number
   of points (reported by Anna Russo)

** changed internal workspace inside gsl_spmatrix to a union to
   avoid casting (suggested by Manuel Schmitz)

   #52230 in msadams (reported by Michael Kaufman) and
   #52336 in msbdf (reported by Andrew Benson). As a fix,
   the maximum scaling of controlled step length was decreased
   from 5.0 to 4.9.

** add histogram2d figure to manual (was missing in 2.4)

** bug fix in gsl_spmatrix_add for duplicate input arguments
   (reported by Alfredo Correa)

** add support for negative arguments nu in gsl_sf_bessel_Jnu and
   gsl_sf_bessel_Ynu (Konrad Griessinger)

** better texinfo documentation for gsl_sf_hyperg functions

** fix vector and matrix fread/fwrite testing on windows systems
   when tmpfile() fails

** fix for rstat/test.c on PPC64 (reported by Adam Majer)
