Latest updates from Sinelabore, including releases, improvements, and announcements.
Latest release: New version 8.0 — editor without GraphViz, events that carry data, lint-clean Rust, and SysML v2 updates.
New version 8.0
November 7, 2026
Version 8.0 improves the built-in state machine editor, the Rust back end and the SysML v2 code generator. New in this version:
Built-in state machine editor: the editor now lays out and draws its diagrams itself. GraphViz no longer has to be installed — see Built-in Visual …
New version 7.5
October 4, 2026
Update for SysML v2. A state machine can now accept a signal directly and work with what it carries, durations are written in the units a model uses, and a send reaches a part from wherever the model writes it. Both code targets, C++ and Python, generate all of it. Highlights …
New version 7.3
September 13, 2026
Update for SysML v2. The same model now generates Python as well as C++, and the generator can draw a model instead of generating from it. A part also drives itself: process() steps the state machines it owns, so a test driver calls one method on the top part and nothing else. …
New version 7.2.9
August 14, 2026
Update for SysML v2. This version removes two long-standing restrictions — models may now span several files, and an action can drive a part other than its own. It also adds units, a documented set of diagnostic codes, and a number of correctness fixes in state machines. …
New version 7.2.6
July 16, 2026
Update for SysML v2. This version continues to expand the textual modeling subset with better packaging, specialization, and state machine support. Highlights since 7.2:
Same-file package imports: membership imports (e.g. import Types::Sensor;) and wildcards (import Types::*;) …
New version 7.2
June 22, 2026
Update for SysML v2. This version improves code generation and adds support for more SysML v2 features. Main improvements are to improve features relevant for state machine handling.
State machine improvements: final states, do assign actions, accept when transitions, and nested …
New version 7.1
March 1, 2026
Update for SysML v2. This version improves code generation and adds support for more SysML v2 features. For example, actions are now treated as first-class SysML v2 features and represented as structs in the generated code instead of methods. Check out the GitHub examples for …
New version 7.0
November 1, 2025
SysML v2 is here and marks a major leap forward in systems modeling. Version 7.0 supports generation of CPPX code from a SysML v2 textual model. With a small framework, the generated parts and state machine code can be executed and tested easily.
SysML v2.0 - First Experiments
July 1, 2025

New version 6.5.1
February 2, 2025
In addition to several improvements, support for additional command-line parameters when using -l cppx was added. You can now optionally specify -std to enable all necessary parameters for language features in version 11 or 14, which simplifies configuration for new users.
New version 6.5.2
February 1, 2025
This version is recommended for all users. Core modules were refactored for better maintainability and consistency, test coverage was improved, and CPPX code generation was updated to avoid unnecessary dynamic memory allocations.
New version 6.4
September 1, 2024
Since version 6.4, history state handling has changed. Transitions can now end in a history state, and only then the previous history is considered when entering the state set; otherwise, the default entry chain is used. The new TransitionsCanEndInHistoryStates parameter enables …
New version 6.3.4
August 1, 2024
This release adds another way to influence the signature of the processEvent() method in C++.
New version 6.3.3
June 1, 2024
This version includes small updates for the Python backend and fixes an issue in the C# backend.
New version 6.3.2.1
February 18, 2024
Bugfix in the C++ backend relevant for users with state machines that have regions and do not want event handler parameters. In the previous version, a msg parameter was incorrectly generated for the region handler code. This is now corrected.
New version 6.3.2
February 18, 2024
A state machine with regions can be in more than one state at a time. Previously, getInnermostActiveState() returned only the topmost active state. With this release, selected backends can return multiple active states to better reflect runtime behavior.
