We are happy to announce Verum-Dezyne 2.16 which introduces the
defer keyword: A new language concept for implementing an
asynchronous interface. With defer, the basic semantics are complete.
Defer replaces dzn.async ports feature that cannot be used in systems collateral blocking. The use of dzn.async ports is now deprecated.
Also new in this release: Cleanups to the code generators and model to model transformations.
See also the Verum-Dezyne documentation.

Changes in 2.16.0 since 2.15.4
Verum's Dezyne-IDE package has been rebranded as Verum-Dezyne.
For changes in the Dezyne core see Dezyne core release 2.16.0.
Verum-Dezyne is the commercial Integrated Dezyne Environment (IDE) by Verum, created especially for the demanding, or the professional Dezyne developer. It is built around the FLOSS command-line version of Dezyne: While Verum-Dezyne is a must for any productive developer, it is "only" a convenience; because all core dezyne tools are free and open source software, there is never any chance of vendor lock-in. Also, by buying Verum-Dezyne, you get support on Dezyne and are sponsoring the development of the Dezyne command-line tools.
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.
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.
