Release Notes

Version history and changelog for Paracore.

V3.0.2 (February 2026) — The Magic of Automatic Data Discovery​

This release marks a fundamental shift in the Paracore engine, moving away from string-based lookups toward a professional, type-safe architecture that automatically discovers Revit elements for you.

🏛️ Major Architectural Shift (Breaking Change)​

[!CAUTION] CRITICAL BREAKING CHANGE: V3.0.2 officially removes support for string-based Revit element extraction. Legacy scripts using strings for Revit elements will no longer function. All scripts must be updated to the professional Automatic Discovery system. Please refer to the updated Paracore-Examples for the new "Gold Standard" implementations.

  • 💎 Automatic Revit Discovery: Direct access to real Revit objects like Wall, Level, or List<Room> in your Params class. Paracore finds them and lists them for you automatically.
  • ⚡ Reactive Compute: _Options providers are now reactive, allowing dynamic UI updates based on other parameters.
  • 🪄 Stateless Logic: The engine now clears previous selections when clicking "Compute," ensuring a clean state for every run.

🎨 Comprehensive UI Overhaul & Refinements​

  • 🔄 Smart Context Sync (Multi-Doc Safety): The UI is now aware of which Revit document a value was computed in. If you switch files, a Triangle Warning appears on compute/selection buttons. The tooltips now identify both the "Previous Document" and "Current Document," prompting a recompute to prevent execution failures from stale or non-existent element references.
  • 🚀 High-Scale Input Virtualization: We've implemented heavy-duty virtualization for Dropdowns and Multi-Select checkboxes, easily handling tens of thousands of elements with zero lag.
  • 🔍 Universal Search: Every dropdown now includes a search box (previously reserved for multi-select), ensuring effortless navigation through large datasets.
  • 📂 Bulk Group Controls: Added "Expand All" and "Collapse All" buttons to the parameter groups, allowing users to toggle all categories at once.
  • 🇽 Focus/Hero Mode Refinement:
    • Enhanced look and feel with a new smooth zoom-out animation upon entry.
    • Stability Fix: Resolved a critical bug where the gallery would become blank when switching sources or signing out while in Focus Mode. The app now gracefully exits Focus Mode during these lifecycle changes.

🛠️ Professional Stability & Reliability​

  • 🚀 Sidecar Process Management: We've overhauled the lifecycle management of the local Python sidecar (rap-server). Paracore now correctly terminates the server process upon app exit. This prevents orphaned processes from hanging on Port 8000, ensuring a clean environment for local development and preventing system resource waste.
