Happy git cloning :-)

The development of Coq has been initiated in 1984 at INRIA by Thierry Coquand and Gérard Huet, then joined by Christine Paulin-Mohring and more than 40 direct contributors.

The first public release was CoC 4.10 in 1989. Extended with native inductive types, it was renamed Coq in 1991.

Since then, a growing community of users has shared its enthousiasm in the originality of the concepts of Coq and of its various features, as a richly-typed programming language and as an interactive theorem prover.

The final release of Coq 8.4 is now available. Its features among other things a modular and uniform extension of the arithmetical libraries and a new proof engine providing bullets. See the dedicated page or download page for more details.

Coq 8.4 is available as a release candidate. More on the Coq 8.4 web page...
