Dear Frama-C users,

The Verification Group at Fraunhofer FOKUS has released a new version (19.0.0) of “ACSL by Example”.
This version is intended for Frama-C 19.0. 
As usual, its source can be accessed through Github

          https://github.com/fraunhoferfokus/acsl-by-example

The PDF document can be directly accessed through

          https://github.com/fraunhoferfokus/acsl-by-example/blob/master/ACSL-by-Example.pdf

We would like to thank everyone who identified problems in “ACSL by Examples”.


There are several changes in this release which are detailed in the changes section of the PDF.
We highlight here only a few of them.

- Change the return types of logic functions that returned int to ACSL’s integer.
   This fixes inconsistencies that occurred in some examples.
- Fix a typo in postcondition of find.
- Rewrite several axiomatic definitions into explicit, recursive ones.
- Add new examples ‘merge’ and ‘count2’ (with an inductive predicate)
- Use Travis-CI on GitHub
- Rewrite specifications of remove_copy and remove examples.



We hope this document helps you in your work with Frama-C/WP.

Regards

Jens Gerlach
