Why changelogs matter for simulation tools
Simulation outputs can change when assumptions, data pipelines, or metric definitions evolve. A changelog makes these shifts visible and traceable.
Without version history, users cannot reliably compare results produced at different times.
What each changelog entry should include
Each release should list affected modules, nature of change, expected impact on outputs, and any migration notes for interpretation.
Mark whether the update is cosmetic, methodological, or data-related so users can prioritize review.
Version-aware analysis
When comparing studies, note the version used and check for relevant changes since that release. This avoids mismatched conclusions.
Version-aware workflows improve consistency and reduce false signal from tool evolution.
Next steps
Apply this resource alongside simulation analysis. Start from the home workflow, validate assumptions in methodology, and use related blog posts to deepen context before changing contribution policy.
Questions about this resource
How should I use the changelog page?
Use it as a reference layer before interpreting simulation outputs. Clear definitions and process notes improve consistency and reduce interpretation drift across scenarios.
Who is this resource designed for?
It is designed for self-directed ETF investors and portfolio thinkers who want transparent assumptions, risk-aware analysis, and reproducible decision workflows.
Does this resource replace financial advice?
No. It provides educational context and methodology support. Investment decisions should reflect your own constraints, objectives, and risk capacity.
