[*] 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 2.15.2 since 2.15.1

• Build

  • The test suite now passes on i686-linux.

• Code

  • The c++ runtime now avoids making unnecessary copies.
  • The c++ runtime now avoids construction of trace strings when tracing is disabled.
  • The experimental c, javascript, and scheme code generators now pass the test suite for their partial supported feature set.

• Noteworthy bug fixes

  • The parser now accepts on <event>, inevitable: and on <event>, optional:. This was a regression since 2.9.1.

  • The dzn graph command now also honors the -m,--model option for --format=json.

  • The dzn graph --backend=state command now produces sorted output.

  • The simulator no longer changes the state of the provides port without showing provides port interaction when using -C,--no-compliance.

  • The order of -I,--import options is now preserved.

  • The dzn code generator has been fixed by:

    • Adding spacing for port qualifiers,
    • Adding support for blocking port qualifier,
    • Preserving data type definitions,
    • Preserving the scope of of function types,
    • Including import statements.

  • A bug was fixed in the experimental c code generator with respect to negation in expressions.

  • The experimental javascript and scheme code generators now support reply on a synchronous out event.

  • The experimental c, javascript and scheme code generators now use a colon (:) as separator between the enum-type and enum-field, in compliance with this change in 2.13.0.

  • The experimental scheme code generator now supports non-collateral blocking, i.e., exclusively in the top component of a system.

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.
