   Dear All,   
      
   We are happy to announce a new edition of   
   the Dogelog player:   
      
   - Enhanced library(lists):   
      We made the predicate free_variables/3 now public   
   in library(lists). It implements then ISO core standard   
   specification ISO 7.1.1.4 of witness variables. The   
   predicate does not appear in the Novacore kernel.   
      
   - Enhanced library(sequence):   
      As an alternative we provide a new predicate firstof/2.   
   The predicate is bootstraped from what is used in   
   distinct/1, but makes use of free_variables/3 to determine   
   the keys for deduplication during backtracking. Has more   
   logical properties than distinct/2.   
      
   - New library(plot):   
      The library(plot) can generate line plots in the form   
   of a SVG element. We currently provide the predicates   
   plot/1 and plot/2 which take a list of points (x,y1,..,yn)   
   and plot the lines (x,y1) ... (x,yn). The binary predicate   
   allows specifying various plot options.   
      
   Have Fun!
