   Dear All,   
      
   We are happy to announce a new edition   
   of the Dogelog Player:   
      
   - Enhanced GC:   
   To lift the native stack limitations, we   
   opted for a marking algorithm based on   
   Peter Deutschs algorithm E as found in   
   Donald Knuths "The Art of Computing Programming"   
   book. Our variant uses an int field that was   
   anyway recently introduced for Prolog   
   compound coloring, so that no extra space   
   was introduced in this release.   
      
   - Enhanced Binary-Ops:   
   By adopting the pointer approach from Jaffar's   
   Unification we could get rid of the map based   
   realization from previous releases for union   
   find. It turns out this gives quite a speed   
   advantage. We also lifted the native stack   
   limitation by using an extra space in the   
   form of a stack and a log, which surprisingly   
   performs well especially for Java, less for   
   JavaScript and Python.   
      
   - Enhanced Unary-Ops:   
   For unary operations such as term_variables/2,   
   ground/1, etc.. we experimented with both   
   Peter Deutsch and a stack / log approaches.   
   Interestingly for performance reasons we had   
   to dismiss the two phase approach induced by   
   a marking algorithm such as Peter Deutsch,   
   and went also with the one phase approach as   
   offered by a stack / log realization.   
      
   Have Fun!
