CARA v2.6.8 - Expanded Player Stats and Bug Fixes

Release Date: 05.04.2026

This release substantially extends the Player Stats view with new calendar-based progression charts (Accuracy progression, Move quality progression, ACPL progression by phase), a configurable activity heatmap, richer chart customization (including context-menu toggles for time-series charts), and reworks the accuracy distribution chart to match the newer implementations.

Player Stats is now fully customizable: you can show or hide individual sections to match your preferences. It also improves narrow-layout behavior, addresses a rare crash during bulk analysis when stats recalculated intermittently, fixes missing window borders on some Linux variants, and updates the HTML user manual for the new capabilities.

New Features

  • Player Stats – Customization: Use menu toggles to show or hide any section.
  • Player Stats – Accuracy progression: For games with usable PGN dates, buckets games along a calendar timeline and plots median per-game accuracy (combined, as White, and as Black).
  • Player Stats – Move quality progression: Uses the same calendar time bins as Accuracy progression. In each bin, plots median per-game shares of best moves, top-three moves, and blunders as three lines on one chart.
  • Player Stats – ACPL progression by phase: Uses the same calendar time bins as Accuracy progression. In each bin, plots median per-game ACPL (average centipawn loss) for opening, middlegame, and endgame separately (lower is better).
  • Player Stats – Activity heatmap: New configurable chart of when games were played (requires PGN dates).

Enhancements

  • Accuracy distribution chart: Reworked to align with newer chart implementations.
  • Player Stats – UI/UX: Clearer indication when statistics are (re-)calculating.
  • Player Stats – Narrow layouts: Better narrow-width / reactive layout behavior in the Player Stats view.

Bug Fixes

  • Player Stats: Fixed a rare stack overflow issue during bulk analysis when stats were recalculated intermittently.
  • Linux (amd64, Wayland): Fixed missing window borders on some amd64 Wayland configurations.

Documentation

  • User manual: HTML manual updated with expanded Player Stats documentation and follow-up refinements.

For installation instructions and more information, see the README.
