[*] 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 2.16.2 since 2.16.1

• Language

  • In a valued function, after an "illegal" a return is no longer required.
  • Shadowing of a type name with a variable identifier is now a well-formedness error.
  • Compound namespace definitions are now supported.

• Noteworthy bug fixes

  • A bug in the C++ and C# runtime has been fixed that could lead to reading from an empty list of timers when using defer.

  • The C++ code generator no longer generates multiple includes when multiple interfaces are defined in one file (#75).

  • The simulator now produces a correct split-arrow trace for certain models with a V-fork compliance error.

  • A crash in normalization has been fixed for certain models with non-deterministic guards.

  • The well-formedness check now gracefully handles an action with an undefined type, used in an expression, and report the error.

  • The parser no longer crashes when using a comment on an enum field.

  • The `inline-functions' transformation now correctly handles the optional list of function names and also transforms function bodies.

  • A system diagram can now also be generated for some incomplete (faulty) systems.

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.
