Levent Erkok <erkokl@gmail.com> Thu, Jul 20, 2017, 1:10 AM to Haskell I'm pleased to announce v8.1 release of SBV, a library for integrating SMT solvers into Haskell. This is a release with many new features. Some highlights: * Support for symbolic sum-types: Maybe/Either. (Thanks to Joel Burget for initiating these.) * Support for symbolic sets. * Support for uninterpreted-function values in models. * Support for validation of models coming from SMT-solvers for high-assurance. * An implementation of Dijkstra's weakest-precondition logic and a toy language for showing how to do Hoare style total-correctness proofs in SBV. * A new and better interface to the optimization engine supporting arbitrary metric spaces. * A bunch of other fixes, improvements, and examples. Full release notes are here: https://github.com/LeventErkok/sbv/blob/master/CHANGES.md Hackage: https://hackage.haskell.org/package/sbv Homepage: http://leventerkok.github.io/sbv/ Feedback and bug reports are most welcome. Happy proving! -Levent.
