5.1:

- improvements to GC
   2 generations
   generic speedups
- new scheme for attvars
   - hProlog like interface also supported
- SWI compatibility layer
   - extra predicates
   - global variables
   - moved to Prolog module
- CLP(R) by Leslie De Koninck, Tom Schrijvers, Cristian Holzbaur, Bart
Demoen and Jan Wielemacker
- load_files/2

from 5.0.1

- WIN32 missing include files (untested)
- -L trouble (my thanks to Takeyuchi Shiramoto-san)!
- debugging of backtrable user-C preds would core dump.
- redeclaring a C-predicate as Prolog core dumps.
- badly protected  YapInterface.h.
- break/0 was failing at exit.
- YAP_cut_fail and YAP_cut_succeed were different from manual.
- tracing through data-bases could core dump.
- cut could break on very large computations.
- first pass at BigNum issues (reported by Roberto).
- debugger could get go awol after fail port.
