[Frama-c-discuss] Annoucement: release Why 2.28

  • Subject: [Frama-c-discuss] Annoucement: release Why 2.28
  • From: Claude.Marche at (Claude Marche)

Why release 2.28 is now available on

This release provides a new version of the Jessie plugin which is now 
compatible with Frama-C release "Carbon". Note: it is *not* compatible
with earlier versions of Frama-C.

It also provides a few changes with Why 2.27: support for more provers 
or more recent versions of provers, and a few bug fixes. A special 
effort was made to replace uninformative messages (like "assertion 
failure") by more informative ones. See also the new section "trouble 
shooting" at the end of the Jessie documentation (in the Frama-C 
distribution, and hopefully soon on the Frama-C web page).

There is also a special new feature, which will be announced in a few days.

Below is an excerpt of the changes, see file CHANGES for more details.

Hoping this is useful,

Merry Christmas to all!
