Changelog
A chronological history of features and improvements.
- Robust PGN Parsing: Repertoires with NAG annotations (
!, ?, !!, ?!), accented comments and nested variations now upload cleanly — the previous chesslib crash on tokens like d3! inside variations is fixed
- PGN Comments: Comments embedded in your PGN are now stored per move and surfaced in the repertoire panel
- PGN Board Annotations: Lichess-style
[%csl] coloured squares and [%cal] coloured arrows embedded in your PGN comments are rendered on the board when the hint is active
- Transposition-Aware Repertoire: Repertoire matching now compares positions (FENs) instead of move order, so transpositions are recognised and PGNs that start from an advanced
[FEN] work correctly once you reach that position
- Advanced Start Repertoires: PGN uploads that use
[SetUp "1"] [FEN "..."] to start from a deeper position are parsed and suggested correctly
- Button-Driven Panels: Quick-status cards no longer toggle expand when you click anywhere inside them. Each card now has a dedicated footer button: Show Moves & Comments, Show Sparring Moves, Show My Moves
- Engine Footer Consistency: Show/Hide eval and Lines buttons in the Engine card now use the same style and right-aligned layout as the other quick-status buttons
- Renamed "Show Move" → "Best Move" in the repertoire footer for clarity
- Repertoire Hints: New Hint and Show Move buttons in the repertoire status bar — get a piece highlight or a full arrow on the board when you're stuck
