dartchess/CHANGELOG.md

0.13.0

Breaking changes:

• Remove fast_immutable_collections dependency. Public APIs that previously returned IMap or IList now return standard Dart collections:
  • Position.legalMoves returns Map<Square, SquareSet> (was IMap<Square, SquareSet>)
  • Board.materialCount returns ByRole<int> / Map<Role, int> (was IMap<Role, int>)
  • Castles.rooksPositions returns BySide<ByCastlingSide<Square?>> / Map (was IMap-backed)
  • Castles.paths returns BySide<ByCastlingSide<SquareSet>> / Map (was IMap-backed)
  • PgnComment.shapes returns List<PgnCommentShape> (was IList<PgnCommentShape>)
  • makeLegalMoves() returns Map<Square, Set<Square>> (was IMap<Square, ISet<Square>>)
  • The BySide<T>, ByRole<T>, and ByCastlingSide<T> typedefs are now aliases for standard Map types.
• Pockets.value is removed; use Pockets.of(side, role), Pockets.count(role), Pockets.size, Pockets.hasQuality(side), and Pockets.hasPawn(side) instead.
