| * | Frame expressions are now checked to be well formed. | Rustan Leino | 2013-02-13 | |
| | | | | | | | | (A nice consequence of this is that the method IsTotal is no longer needed.) | |||

* | Support for copredicates and prefix predicates in comethods. | Rustan Leino | 2012-12-04 | |
| | | | | | | (Missing from the co support are (prefix) equalities of codatatypes, various restrictions on the use of co/prefix-predicates, and tactic support for applying the (prefix-)induction automatically.) | |||
* | Parse prefix predicates/methods | Rustan Leino | 2012-11-24 | |
| | ||||
* | Beefed up loop invariant to prove a functional postcondition in a test case. | Rustan Leino | 2012-11-24 | |

| | ||||
* | Included "all cases of a datatype" property for method in-parameters (see ↵ | Unknown | 2012-10-17 | |

* | Added some axioms to try to recover boxed data. In particular, any element ↵ | Unknown | 2012-10-17 | |
| | | | | 'x' of a set in the encoding satisfies Box(Unbox(x))==x. The soundness and performance of the axiomatization are dicey, so the axioms are made available only to method in-parameters. | |||

* | New feature: | Rustan Leino | 2012-10-11 | |
| | | | | | | | * Added "comethod" declarations and support for writing manual co-inductive proofs (but currently blindly assume comethod postconditions to, in positive positions, only have copredicates and codatatype equalities--other cases still need to be dealt with) Code restructuring: * New set of Boogie procedure stubs generated for each other * Start of improvements around TrSplitExpr | |||

* | Added Test/dafny3 and another test file for iterators (hey, you can even run ↵ | Rustan Leino | 2012-10-04 | |
| | | | | | | Iter.dfy!) Fixed migration issues | |||
