Summary of important user-visible changes for releases of the gsl package

===============================================================================
gsl-2.1.0
===============================================================================

** Changes in the family of zeta functions
    > Rename gsl_zt_zeta to gsl_sf_zeta (accidentally named with a wrong prefix
      in the 2.0.0 release; alias names zeta and gsl_zt_zeta still available
      but deprecated)
    > New functions to compute zeta minus one: gsl_sf_zetam1, gsl_sf_zetam1_int

===============================================================================
