Dezyne 2.15.0 released as free software!

May 06, 2022

We are proud and relieved to announce Dezyne 2.15 which completes full support for blocking: This finally marks the Grand Unification into single threaded execution semantics.

The documentation is available here: https://dezyne.org/documentation.html.

We will evaluate your reports and track them via the Gitlab dezyne-issues project, see our guide to writing helpful bug reports.

What's next?

Verification with system scope and automatically exploring possible traces in a system. Introducing a new keyword defer for asynchronous behavior and deprecation of async.

Future

Looking beyond the next releases we will introduce implicit interface constraints. Hierarchical behaviors, module-specifications and data-interfaces. Support for Model Based Testing.

Enjoy!
The Dezyne developers.

Download

git clone git://git.savannah.nongnu.org/dezyne.git

Here are the compressed sources and a GPG detached signature[*]:
dezyne-2.15.0.tar.gz
dezyne-2.15.0.tar.gz.sig

Here are the SHA1 and SHA256 checksums:

395ff05e4f2c17bcee895fd9436d696fb0aab93d  dezyne-2.15.0.tar.gz  
982d8f7cca9de23225e2f06b4c8524c0b57acfba81beaaff1a0c045c1e6409ea  dezyne-2.15.0.tar.gz

The SHA256 checksum is base64 encoded, instead of the hexadecimal encoding that most checksum tools default to.

[*] 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.

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.
