title=Release of Alt-Ergo 2.1.0 authors=Mohamed Iguernlala date=2018-03-14 category=Formal Methods tags=alt-ergo A new release of Alt-Ergo (version 2.1.0) is available on Alt-Ergo's website: [https://alt-ergo.ocamlpro.com/#releases](https://alt-ergo.ocamlpro.com/#releases). An OPAM package for it will be published soon. In this release, we mainly improved the CDCL-based SAT solver to get performances similar to/better than the old Tableaux-like SAT. The CDCL solver is now the default Boolean reasoner. The full list of CHANGES is available [here](https://github.com/OCamlPro/alt-ergo/blob/2.1.0/sources/CHANGES). Despite our various tests, you may still encounter some issues with this new solver. Please, don't hesitate to report bugs, ask questions, and give your feedback!
