March 2025 — Key delivery: startup-time theme usability warning in helix-editor/helix. Added an explicit warning when true color support is unavailable or disabled at startup, replacing the previous silent fallback to the default theme. This improves user experience by providing clear feedback, reduces potential support tickets, and aligns with UX improvement goals and issue #13058.
