division '/' and (uninterpreted) real exponentiation '**', real literals and coercion functions 'int' and 'real';
Integer operations 'div' and 'mod' are now mapped to corresponding SMT-LIB operations instead of treating them uninterpreted;
Made unary minus valid Boogie syntax again (the expression '- e' used to be rewritten by the parser to '0 - e', now this is done when generating VCs);
Extended the BigDec class with additional functionality;
Added test cases for SMT-LIB prover backend (the Z3 API interface has been adapted accordingly, but is untested)

interval-based abstract interpretation instead.
Command-line option '/infer' now accepts only arguments 't' and 'j' where the latter is the default now for Boogie.
Command-line option '/logInfer' has been dropped.

Expr's, not the more abstract AIExpr's.
Boogie: Added Trivial Domain (/infer:t), which just detects assume/assert false.
Boogie: Added new Interval Domain (/infer:j), which is stronger than the /infer:i intervals (because the also include preconditions, booleans, and more constraints) and may also be more efficient than previous intervals
Boogie: Mark all inferred conditions with attribute {:inferred}

* Bug fix: Changed checking of postconditions to follow the order in which ensures clauses are given (not reverse order, as was previously the case)
* Added command-line option (/instrumentInfer) that decides how to instrument the Boogie program with inferred invariants. Previously, the only option was to instrument at the beginning and end of every basic block. The new option, which is now the default, is to instrument only at the beginning of loop heads.
* Add empty blocks between other blocks only as needed, and try a little harder to retain source information when blocks are peep-hole optimized
* Renamed flag /noRemoveEmptyBlocks to /removeEmptyBlocks:<c> where <c> is 0 or 1
Boogie refactoring:
* Removed LoopPredicate class and related classes and methods left over from when (back in the Zap 2 days) we supported loop invariants on demand
* Cleaned up some parsing of command-line options
