[*] 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 2.18.4 since 2.18.3

• Verification

  • The unreachable code check now considers the use of individual triggers in an on-statement.

• Noteworthy bug fixes

  • A false negative deadlock when using shared state in an interface that uses a function has been fixed. This was a regression introduced in 2.18.3.

  • A bug in the code generator was fixed to handle a call with more than two arguments that are calls.

  • A bug in the code generator was fixed when using defer in a component with a data member without state members.

  • A bug in the parser was fixed to ignore anything between dollars ($..$), i.e., also the string "import".

  • Several bugs in the dzn code --language=dzn pretty-printer have been fixed for nested namespaces, shared variables and void returns.

  • The test framework can be built using gcc-14.

  • A bug in the simulator with respect to eligible labels in defer context has been fixed.

  • The verification performance impact due to the semantic extension of shared state has been resolved.

For changes in the previous release see Dezyne release 2.18.3.

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.

The Dezyne research and development on the language and command line tooling, also known as the Dezyne core, is the responsibility of Reasonable Sourcery commisioned by Verum.

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.
