[*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this:

gpg --verify .sig

If that command fails because you don't have the required public key, then run this command to import it:

gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273

and rerun the 'gpg --verify' command.

NEWS

Changes in 2.15.1 since 2.15.0

• Build

  • Tests that produce unstable witnesses have been disabled so that the test-suite now passes with different builds of mCRL2 that, in case of multiple counter examples, leads to reporting one of them (pseudo) randomly.

• Noteworthy bug fixes

  • Verification no longer erroneously reports a deadlock when using blocking in a synchronous context.

  • The simulator no longer prints the initiating port event arrow twice which would lead to an invalid split-arrows trace for certain compliance errors.

  • The simulator now synthesizes the missing port action in case of a compliance error, to produce a complete split-arrows trace.

  • The simulator now reports a second reply error at the return of a void event if a reply was already set.

  • The simulator now reports a deadlock when using a void reply in a non-blocking synchronous context.

  • The simulator no longer reports a deadlock when using a skip-block reply in a function.

  • The simulator now correctly postpones flushing in system context when using multiple out events on a single modeling event until all events are enqueued.

About Dezyne

Dezyne is a programming language and a set of tools to specify, validate, verify, simulate, document, and implement concurrent control software for embedded and cyber-physical systems.

The Dezyne language has formal semantics expressed in mCRL2 developed at the department of Mathematics and Computer Science of the Eindhoven University of Technology (TUE). Dezyne requires that every model is finite, deterministic and free of deadlocks, livelocks, and contract violations. This is achieved by means of the language itself as well as builtin verification through model checking. This allows the construction of complex systems by assembling independently verified components.

Dezyne is free software, it is distributed under the terms of the GNU Affero General Public Licence version 3 or later.

About Verum

Verum, the organization behind the Dezyne language, is committed to continuing to invest in the language for the benefit of all its users. Verum assists its customers and partners in solving the software challenges of today and tomorrow, by offering expert consultancy on the application of the Dezyne language and the development and use of its tools, as well as on Verum's commercial tools like IDE support based on the LSP (Language Server Protocol), interactive integrated graphics, interactive simulation, (custom) code generation and (custom) runtime library support.
