Release Notes: v0.10.1

Release Date: 2025-12-29
Type: Feature
Branch: feature/v0.10.1-custom-palettes

Summary

Adds admin-defined custom color palettes via Dataiku's parameter set (PRESET) mechanism. Administrators can create global color palette presets in plugin settings, and users can select these custom palettes from the Color Palette dropdown when configuring Gantt chart webapps.

Changes

Added

  • Custom color palette support via parameter sets (#79)
    • New "Custom (Preset)" option in Color Palette dropdown
    • PRESET selector appears when custom is selected
    • Admins create palettes in plugin settings with 6-12 hex colors
    • Dynamic CSS injection with WCAG-compliant text contrast
    • Automatic light/dark text based on background luminance

Fixed

  • PRESET parameter resolution in webapps
    • Webapps receive raw references, must resolve via API (unlike recipes)
    • Implemented resolve_preset() function for API-based resolution
