[*] 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.

Alternatively, Dezyne can be installed using GNU Guix:

guix pull  
guix install dezyne

NEWS

Changes in 2.18.2 since 2.18.1

• Code

  • The C++ runtime headers can now be compiled with -Werror -Wshadow; An extra file coroutine.cc was added.

• Simulation

  • The simulator now supports semicolon (;) separated input trails.
  • The simulator now truncates the trace leading up to a non-compliance error at the first offending event.

• Verification

  • The -D,--non-non-compliance option was removed.

• Noteworthy bug fixes

  • A false negative illegal in collateral blocking context will now be reported correctly by verify.

  • A false positive non-compliance error in blocking context is no longer reported by the simulator.

  • A forking compliance error in multiple provides context will now be displayed correctly again by simulate. This was a regression introduced in 2.18.0.

  • The simulator will now prioritize the reporting of an illegal error over a non-compliance, also without using --no-compliance.

  • A crash in the --language=json output has been fixed when not removing a behavior containing functions.

  • The performance degradation of 2.18.0's verify that notably impacts armoring components that weren't upgraded to take advantage of the 2.17 implicit interface constraints feature yet, has been reduced.

For changes in the previous release see Dezyne release 2.18.1.

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 Verum-Dezyne's IDE support based on the LSP (Language Server Protocol), interactive integrated graphics, interactive simulation, (custom) code generation and (custom) runtime library support.
