It is my pleasure to announce the new release for FoCaLiZe (the 0.9.2 version).

As for previous releases, some bugs have been fixed in the focalizec compiler. 
This version introduces the Dedukti backend written by Raphaël Cauderlier, taking benefits from Zenon_modulo to ease proofs. 
The Coq backend now generates Coq code compatible with Coq 8.8. A complete description of changes / new features can in found in the CHANGES file of the distribution.

file of the distribution.

The 0.9.2 release is available from focalize.inria.fr <http://focalize.inria.fr/> at
http://focalize.inria.fr/download/focalize-0.9.2.tgz <http://focalize.inria.fr/download/focalize-0.9.2.tgz>
Uncompress, extract, then read the INSTALL file in the newly created
directory focalize.0.9.2 and follow the simple instructions written there.


A public GIT repository is also available on GitHub (https://github.com/pessaux-f/focalize <https://github.com/pessaux-f/focalize>),
allowing to fetch the latest development state of FoCaLiZe. However, its content
is not bullet-proof and may be unstable at some times. It reflects the real-time
state of FoCaLiZe and may bring fixes and features not available in previous
releases and that will be part of the next release.
To join people and discussions write to focalize-users@inria.fr <mailto:focalize-users@inria.fr>.
Implementors also listen to suggestions (and compliments if some ^_^) at the
mail address: focalize-devel@inria.fr <mailto:focalize-devel@inria.fr>.

Enjoy.

For the entire FoCaLiZe implementation group,

François Pessaux.

What is it FoCaLiZe ?
---------------------

FoCaLiZe is an integrated development environment to write high integrity
programs and systems. It provides a purely functional language to formally
express specifications, describe the design and code the algorithms.
Within the functional language, FoCaLiZe provides a logical framework to
express the properties of the code. A simple declarative language provides
the natural expression of proofs of properties them from within the program
source code.

The FoCaLiZe compiler extracts statements and proof scripts from the source
file, to pass them to the Zenon proof generator to produce Coq proof terms
that are then formally verified.

The FoCaLiZe compiler also generates the code corresponding to the
program as an Objective Caml source file. This way, programs developed in
FoCaLiZe can be efficiently compiled to native code on a large variety of
architectures.

Last but not least, FoCaLiZe automatically generates the documentation
corresponding to the development, a requirement for high evaluation
assurance.

The FoCaLiZe system provides means for the developers to formally express
their specifications and to go step by step (in an incremental approach) to
design and implementation, while proving that their implementation
meets its specification or design requirements. The FoCaLiZe language offers
high level mechanisms such as inheritance, late binding, redefinition,
parametrization, etc. Confidence in proofs submitted by developers or
automatically generated ultimately relies on Coq formal proof verification.

FoCaLiZe is a son of the previous Focal system. However, it is a completely
new implementation with vastly revised syntax and semantics, featuring a
rock-solid infrastructure and greatly improved capabilities.
