Fixes 🐛

• Stabilized initialization of the diagram view

Release v0.11.0

Features 🚀

VS Code Extension:

• Xronos AI Chat ✨ (sign up for early access )
• Dry Run tool for simulating reactor execution from YAML files

Improvements 🛠️

VS Code Extension:

• Dropped dependency on external Node.js to make the extension self-contained

Xronos Dashboard:

• No login required on first use

Release v0.10.0

Features 🚀

• New xronosinc/xronos docker base image with preinstalled Xronos SDKs and tools.

Improvements 🛠️

SDKs:

• Provide more detailed feedback including reaction names when dependency cycles are detected

VS Code Extension:

• Visualize deadline in the reactor diagrams
• Improved handling of errors during diagram generation

Xronos Dashboard:

• Improved visual appearance of the trace panel
• Visualization of deadlines in the trace panel
• Hide trace details when showing large time spans

Fixes 🐛

• Fixed duplicated names in some C++ examples

Release v0.9.0

Features 🚀

• Initial support for specifying and checking reaction deadlines. This includes:
  • New C++ SDK methods: add_reaction_with_deadline(), deadline(), is_before_deadline(), remaining_slack()
  • Visualization of deadlines in the Xronos Dashboard trace panel

Improvements 🛠️

• Improved zooming and navigation behavior in the diagram view of the Xronos VS Code Extension
• Updated the Xronos Dashboard to Grafana 12.4.0

Release v0.8.0

Examples 💡

• Isaac Sim example demoing interaction between Xronos and Isaac.

Improvements 🛠️

• Enforce uniqueness of element names to avoid ambiguity in the diagrams and dashboard. (C++ and Python SDK)
• Provide better error message when a reaction returns no handler or the returned handler is invalid. (Python SDK)

Fixes 🐛

• Fixed platform tag of python wheels.

Release v0.7.0

Features 🚀

• Python source distribution for installation on not officially supported platforms (e.g., macOS)
• Experimental API for specifying serializers (C++ SDK)

Improvements 🛠️

• Shared libraries only export SDK symbols and hide symbols from third party dependencies for better compatibility with external libraries.

Cleanup 🧹

• Simplified the default runtime and removed legacy code

Examples 💡

• Hello World demo comparing a simple demo between ROS2 and Xronos and highlighting some of ROS2's concurrency issues.

Release v0.6.0

Features 🚀

• Modularized the backend infrastructure so that the same Xronos program can execute on different runtimes.
• Added optional runtime_provider argument to execute() allowing the user to provide a different runtime that should be used for execution. (C++ SDK)
• Introduced shutdown effects, allowing reactions to explicitly declare that they might invoke shutdown and providing the trigger_shutdown() method. This replaces the request_shutdown()` method. (Python, C++)

Deprecated 🗑️

• Removed the request_shutdown() method. (Python, C++)

Release v0.5.0

Features 🚀

• Python 3.14 support (Python SDK)
• Installable pre-compiled artifacts (C++ SDK)

Improvements 🛠️

• Fully implemented compilation firewall using pImpl to improve API stability and decouple user code from internal changes (C++ SDK).
• Replaced our build tool earthly with Docker bake
• Added build options for disabling the diagram and telemetry features to allow a minimal build (C++ SDK)

Documentation 📖

• Integrated C++ docs with main documentation website at https://docs.xronos.com/
• Updated and improved C++ and Python API docs
• Show current SDK version

Release v0.4.0

Features 🚀

• New dashboard panel for showing reaction traces

Improvements 🛠️

• Added Reactor.request_shutdown() method (Python)
• Added add_attributes() method to all elements (C++)
• Added get() and is_present() methods to the PortEffect class (C++)
• Periodic timers require a nonzero period (Python)
• Switched lag and execution time panels to showing points instead of interpolated lines (Dashboard)
• Switched execution time panel to logarithmic timescale (Dashboard)
• Disabled auto-refresh by default (Dashboard)
• Improved positioning of "Refresh" and "Back" buttons in metrics view (VS Code)

Fixes 🐛

• Exclude lag from reaction spans shown (Dashboard)
• Correctly display FQNs in the metrics view (VS Code)
• Also include inherited attributes in the metrics view (VS Code)

Examples 💡

• Added Python Webots example showing software-in-the-loop simulation

Deprecated 🗑️

• Removed the deprecated enable_tracing() method (Python, C++)
• Removed Reactor.environment property (Python)
• Removed StartupDeclaration and ShutdownDeclaration (Python)

Release v0.3.0

Features 🚀

• New metrics view showing all the metrics reported by the application in the VS Code extension
• New dashboard panels showing:
  • lag of all reactions
  • execution times of all reactions
  • number of reactions executed in the current time window
  • a metric as selected by the new drop-down menu in the top

Improvements 🛠️

• Compatibility with cmake 4.0.0
• Reduced sensitivity when scaling diagrams in the VS Code extension
• Show informative error message when calling execute() multiple times on the same environment (C++ SDK)
• Introduced enable_telemetry() method in Python and C++ SDKs

Examples 💡
