v2.0.2

Changed

• removed misleading keywords (fen, board-game)
• added threefold-repetition and draw-detection keywords

v2.0.1

Fixed

• Corrected README to match 2.0.0 API: removed nonexistent Game.fromFen() and
  game.fen(), documented new Game(position) constructor, fixed undo() /
  redo() return types (void, not this), fixed Move.promotion signature,
  removed MoveInput from exports listing.
• Updated AGENTS.md to reflect single runtime dependency (@echecs/position),
  removed nonexistent src/fen.ts, added missing test files, removed stale
  references to isAttacked / applyMoveToState, updated naming convention
  examples.
• Changed package.json keyword from no-dependencies to
  minimal-dependencies.

v2.0.0

Changed

• BREAKING: upgraded to @echecs/position v3. Color values are now
  'white'/'black' (was 'w'/'b'). PieceType values are now full words
  ('pawn', 'knight', 'bishop', 'rook', 'queen', 'king') instead of
  single letters.
• BREAKING: CastlingRights shape is now
  { white: { king, queen }, black: { king, queen } } (was
  { wK, wQ, bK, bQ }).
• BREAKING: PromotionPieceType uses full words ('queen', 'rook',
  'bishop', 'knight') instead of single letters.
• BREAKING: constructor now accepts an optional Position argument instead
  of always starting from the initial position. new Game() still defaults to
  the starting position; new Game(position) starts from any Position.
• BREAKING: MoveInput type merged into Move with optional promotion.
  Game.move() now takes Move directly.
• Rewrote move generation to use position.reach() for pseudo-legal targets and
  position.derive() + isCheck for legality filtering. Removed all 0x88
  internal board manipulation.
• @echecs/fen moved from runtime dependency to devDependency. FEN
  parsing/serialization is no longer part of the public API.

Added

• Local Move and PromotionPieceType types (removed from @echecs/position
  v3).
• Re-exported STARTING_POSITION, EnPassantSquare, and SideCastlingRights
  from @echecs/position.
• Full game playthrough test (81-move Fischer-Spassky 1972 Game 6) via
  @echecs/san.
• Zobrist hash consistency tests (move/undo cycles, transpositions).
• Regression edge-case tests ported from chess.js.

Removed

• BREAKING: Game.fromFen() static method — construct a Position and pass
  it to new Game(position) instead.
• BREAKING: game.fen() method — use @echecs/fen directly with
  game.position().
• BREAKING: isAttacked() method — removed from Game. Position v3 no
  longer exposes attack queries.

v1.1.0

Added

• Game.isAttacked(square, color) — returns true if any piece of color
  attacks square. Matches chess.js semantics: pinned pieces still attack, own
  pieces count as attacked squares, no X-ray, same square returns false.

v1.0.0

Changed

• First stable release. No API changes from 0.1.1.
