Yano Simulator release notes

• Build number: 20260809
• Release date: August 09, 2026

⭐ Overview

Yano Simulator 0.2.0 is a major pre-1.0 feature release focused on faster simulation, richer model methodologies, scalable array modeling, and a more responsive authoring experience.

🚀 Highlights

• Native Fast v2 is now the default simulation engine. It adds reusable compiled plans, cached shape handling, deterministic parallel sensitivity and scenario batches, memory-saving output capture, resumable Advance sessions, and live SyntheSim reruns, while retaining transparent fallback for unsupported cases.
• Model Architecture now supports executable hybrid models with SD, ABM, and DES components. Users can define multiple clocks, typed ports, shared values, cross-clock coupling, named events, queues, resources, processes, and methodology-aware output sources in one model.
• Agent Modules now provide contextual authoring for formula-first initialization and recurring behavior. They also support managed populations, movement and neighbor actions, networks, lifecycle events, category quotas, complete agent histories, movement trails, and individual-agent inspection.
• Array modeling now supports saved dimensions and named element sets, relative and range selectors, explicit aggregation and broadcasting, conditional aggregates, per-element equations, graphical-function editing, and safer dimension-aligned evaluation.
• The Equation editor adds multilingual and CJK-friendly authoring, safer quoted references, matching-bracket highlighting, built-in-function highlighting, context-aware array suggestions, and modern IF ... THEN ... ELSE conditionals with legacy syntax normalization.
• Model Details and documentation now support project-wide descriptions, tags, variable notes, and reusable number-to-text mappings. Canvas styling, animated plot export, responsive inspectors, and the Schelling segregation tutorial further improve presentation, analysis, and learning workflows.

🔄 Compatibility

• Existing .yano projects remain the primary editable project format.
• Legacy equation spellings and conditional syntax are normalized to the current canonical forms.
• Unsupported Native Fast v2 cases continue through the compatible fallback path where available.

⭐ Overview

Yano Simulator 0.1.0 marks the first release of our macOS system dynamics modeling app. This release brings the core Yano workflow into a refined desktop experience: build stock-and-flow models visually, run simulations, examine results, design interactive interfaces, document model structure, and exchange compatible models with other tools.

🚀 Highlights

• Visual stock-and-flow modeling on a dedicated canvas with stocks, flows, auxiliaries, connectors, and modules.
• Simulation controls built directly into the workspace, including simulate, advance, pause/resume, stop, restore, and playhead review.
• Interface Designer for polished page-based dashboards, controls, plots, indicators, and presentation-style model views.
• Full-fidelity .yano project packages for native project storage.
• Import support for compatible Yano, XMILE, and Vensim model files.
• Export support for XMILE, JSON, CSV reports, canvas images, PDF, HTML documentation, and LaTeX documentation.

✨ New in This Release

• Build models visually and edit behavior, units, documentation, and style from the Model Inspector.
• Use Workspace plots and tables to review simulation output and compare saved runs.
• Create interactive Interface pages with inputs, action buttons, gauges, values, plots, text, graphics, progress controls, and navigation controls.
• Start Interface pages from built-in templates such as Dashboard, Policy Lab, and Run Manager.
• Run Sensitivity Analysis with Monte Carlo and Markov Chain Monte Carlo workflows, including Random, Latin Hypercube, and Halton sampling methods.
• Run Model Optimization workflows with reusable payoff definitions and CSV result export.
• Generate Model Documentation reports with export options for HTML, CSV, and LaTeX.
• Encrypt native .yano projects for protected storage.
• Access built-in Help covering modeling workflows, simulation settings, equations, interface design, analysis tools, import/export, and troubleshooting.

🔄 Compatibility

• Native .yano packages are the primary editable project format for Yano Simulator.
• The app can import compatible XMILE (.xmile, .xml, .stmx) and Vensim MDL files.
• Imported third-party models may require review of equations, units, and run settings before production use.

⚠ Known Limitations

• Some imported XMILE or Vensim features may not have an exact equivalent and can produce compatibility warnings.
• Diagram Mode is intended for qualitative diagrams and disables per-variable simulation behavior.
• Some application areas or analysis actions may depend on the current subscription state.
• Canvas image and PDF export create visual output, not editable model files.

This document lists the v0.2.0 fixes separately from the feature release notes.

🐛 Fixes

• Large projects open and start simulations more responsively by avoiding repeated validation and package work on the UI thread.
• Global Details, Model Documentation, analysis views, theme controls, loop labels, Help navigation, and Agent controls no longer publish unchanged state during view refreshes.
• Text Boxes now refresh multilingual variable values at every playhead time, and saved appearance settings persist after reopening.
• Model Architecture reliably reopens, updates canvas equations after edits, repairs generated duplicates, and validates current Agent Module changes correctly.
• Agent Module initialization, randomization, mappings, field equations, dark-mode labels, and per-agent persistence now behave consistently.
• Application Settings’ Restore Defaults now resets persisted appearance, theme, palette, and canvas-export preferences after confirmation.
• Equation editing and validation now preserve multilingual names, CJK composition, punctuation, numeric-leading references, array selectors, manual loop polarity, and legacy syntax normalization.
• Array equations now validate and evaluate correctly across relative selectors, ranges, aggregates, dimensions, stock initialization, stateful functions, imports, and per-element equations.
• Plot legends, headers, calendar axes, annotations, selected-object exports, resize handles, hit testing, and Agent Network styling now match the configured selection and presentation.
• Simulation stopping, zero-duration runs, early previews, history initialization, update checks, and Native Fast v2 build diagnostics are more reliable.
