10 * Isabelle tool "wwwfind" provides web interface for 'find_theorems' 
10 * FIXME 
11 on a given logic image. 

12 

13 * HOLSMT: proof method "smt" for a combination of firstorder logic 

14 with equality, linear and nonlinear (natural/integer/real) arithmetic, 

15 and fixedsize bitvectors. 

16 

17 * HOLBoogie: an interactive prover backend for Boogie and VCC. 

18 

19 * HOL: counterexample generator tool Nitpick based on the Kodkod 

20 relational model finder. 

21 

22 * HOL: predicate compiler turning inductive into (executable) 

23 equational specifications. 

24 

25 * HOL: refined number theory. 

26 

27 * HOL: various parts of multivariate analysis. 

28 

29 * HOLLibrary: proof method "sos" (sum of squares) for nonlinear real 

30 arithmetic, based on external semidefinite programming solvers. 

31 

32 * HOLCF: new definitional domain package. 

33 

34 * Revised tutorial on locales. 

35 

36 * ML: tacticals for subgoal focus. 

37 

38 * ML: support for Poly/ML 5.3.0, with improved reporting of compiler 

39 errors and runtime exceptions, including detailed source positions. 

40 

41 * Parallel checking of nested Isar proofs, with improved scalability 

42 up to 8 cores.
