Release Notes

Stay up to date with the latest features, improvements, and fixes in Simulate.

Simulate 0.6.1 - Premium Goes Live

  • Premium payments are now live. PayPal checkout uses real payments — sandbox mode is off.
  • Upgrade page padding and spacing fixes for consistent display across devices.

Simulate 0.6.0 - Premium & UI Polish

  • Simulate Premium is here: upgrade to 4 inputs, 4 outputs, unlimited runs and daily simulations for a one-time payment of $9.
  • Upgrade page redesigned with full simdss.com branding, feature comparison table, and polished post-payment confirmation.
  • Sidebar upgrade CTA moved to the bottom of the sidebar as a non-intrusive card.
  • Premium users see a "Premium" badge next to the Simulate title instead of "Beta".
  • Free tier run options (500, 1000, 2000, 5000) are now visibly locked with a "Premium" label in Settings.
  • Added "How do I buy Simulate Premium?" to the FAQ.

Simulate 0.5.6 - Small UX Fixes

  • Correlation dialog now says “Open correlations" and keeps polling tidy (no noisy console logs, safer cleanup when closing).
  • Correlation inputs keep the green focus style instead of flashing blue.
  • You can’t delete inputs/outputs while a run is preparing or running; delete spinner reliably shows during cleanup.
  • Minor save-flow hardening in correlations to avoid janky state after closing the tab.

Simulate 0.5.5 - Stability & Reliability Polish

  • Fixed histogram off-by-one (all results now show). Thanks, Nicolas.
  • Block input deletion during runs to avoid data loss.
  • Correlation sidebar refreshes reliably and clears pairs when inputs change.
  • Correlations auto-save after 2s with a brief “Saved ✓" toast.
  • UI text styling tightened (incl. “No inputs" message).
  • Polling and logging tuned for clearer correlation updates.

Simulate 0.5.4 - Website Restructure

Home page matches what most of you want first: Simulate up front, FPOM close by, updates in one place.

  • simdss.com now opens directly to Simulate (no extra clicks).
  • FPOM Calculator lives at /fpom/, still fully available.
  • Navigation reordered: Simulate first, then FPOM Calculator.
  • Release notes live on the main site for easy discovery.

Simulate 0.5.3 - Smoother & More Reliable

Less friction, fewer surprises: clearer states, self-healing sheets, and consistent messaging.

  • Added a “preparing" state: Preparing → Running → Done; no double starts.
  • Auto-rebuilds broken simulation sheets (missing/corrupt headers).
  • Correlation summary restored with consistent labels across views.
  • Standardized help/error text for clearer status messages.
  • Start button stays disabled until prep completes to avoid race conditions.

Simulate 0.5.2 - Stop Actually Means Stop

This one is about trust: when you hit Stop, it really stops, and the UI stays tidy and clear.

  • Stop now clears outputs immediately and resets the UI; no leftovers.
  • Re-run button only shows when it should—no accidental double starts.
  • Correlations show readable labels (e.g., “Sales Growth (Uniform)").
  • Error/warning messages use consistent, clear styling.
  • Cleaned background processing; removed unused pause/resume endpoints.

0.5 Beta Release Notes

This beta keeps you moving: stop mid-run, keep the data you already paid for in compute, and see clearly what’s happening without fighting the UI.

  • Added “Stop & Show Results" to cancel runs and keep partial outputs.
  • Clear run status: progress bar + alerts to avoid deleting the temp sheet.
  • Softer UI for inputs/outputs/settings and clearer primary actions.
  • Error toasts are shorter, higher contrast, and auto-dismiss quickly.
  • Added regression tests for error handling and state recovery.
