The Coq development team is pleased to announce the release of Coq version 7.4. This version provides several novelties, including a new system of parametric modules and interfaces, and support for the Why (http://why.lri.fr) and Krakatoa (http://www.lri.fr/~marche/krakatoa) systems. However, this version is still experimental and does not fully support the functionalities of the previous version 7.3.1 (especially ast-based grammar extensions are off). Please refer to the accompanying document CHANGES or the location ftp://ftp.inria.fr/INRIA/LogiCal/coq/V7.4/doc/Changes.html for a full list of changes including sources of incompatibilities. Coq V7.4 is available in several formats from http://coq.inria.fr/ and ftp://ftp.inria.fr/INRIA/coq/V7.4/ The documentation is available in postscript, pdf and html format.
