Added

• Bee Flow Chess, a new chess variant named after Bee-Flow, the private AI workspace, at the top of the variants
  list: protect your Queen Bee. Each back rank is shuffled on its own, enemy pieces show as honeycomb cells until they
  move, and a privacy shield keeps the pieces next to the Queen Bee from being captured. Against the computer, as pass
  & play, and online with the server as the umpire and a rating of its own.

Quantum Chess 2.1.0

The chess variants go online.

Added

• Online play for the two-player chess variants: 3D, 4D and 5D chess, Tri-Dimensional chess, Chess960, Atomic,
  Crazyhouse, Antichess, King of the Hill, Three-check, Horde, Hexagonal chess, Capablanca chess, Shogi, Xiangqi and
  Makruk. Choose Online as the opponent in a variant's New game dialog and invite someone or open a challenge. The
  server draws the dice of every move; both players' devices check every move against the rules, and if they ever
  disagree, the game is annulled.
• Four-player chess and Bughouse online: choose a player for every seat, or leave seats open for anyone to join,
  optionally with random seats. Each invited player answers on their own, and the game starts when every seat is taken.
  Resigning or running out of time ends the game for everyone (the other team wins, or the others share the win); a
  draw needs every player.
• Kriegspiel and Fog of war online, with the server as the umpire: it keeps the whole board, decides every move and
  sends each player only what they may see. In Kriegspiel a move the umpire refuses uses no turn and is not told to
  your opponent; in Fog of war you see the odds of a move before you confirm it. The whole board and every move are
  shown when the game ends. With this, all twenty chess variants can be played online.
• A rating for every two-player variant: rated variant games count in a rating of that variant, shown on the
  Statistics page with the leaderboard of each variant. Kriegspiel and Fog of war are rated by default; the other
  variants when you ask for it and your opponent accepts. Games of four are not rated.
• Rematches of variant games: the Rematch button after an online variant game; in a game of four every player
  moves on by one seat.

Quantum Chess 2.0.1

Maintenance release, and the first step towards playing the chess variants online, four-player games included.

• Updated the Nextcloud components of the app.

Quantum Chess 2.0.0

Quantum Chess 2: twenty chess variants with the quantum element of the classic game, led by 5D chess with multiverse
time travel. The variants are played on your own device; online play, ratings and the rules engine of classic Quantum
Chess are unchanged.

Added

• Multiverse chess (5D), the quantum version of 5D Chess With Multiverse Time Travel: timelines as rows and time
  as columns; pieces that travel back in time and to other timelines, where a move onto an older board opens a new
  timeline (up to three per player, or four on a laptop: an option); turns with a move on every must-move board of the present, ended by
  Submit turn; every official piece (unicorn, dragon, princess, brawn, common king and royal queen) and 44
  official start positions, Small (5 × 5) by default. Boards are certain and pieces are quantum: ghosts, twins and
  links on every board, the past included. A turn that cannot be finished ends the game as checkmate or stalemate, and a
  move that would strand your own turn asks first.
• Nineteen more chess variants, grouped as in the app:
  • Other dimensions: 3D chess (Raumschach), Tri-Dimensional chess with movable attack boards and 4D chess.
  • Hidden information: Kriegspiel and Fog of war.
  • Different rules: Chess960, Atomic, Crazyhouse, Bughouse, Antichess, King of the Hill, Three-check and Horde.
  • Different boards and more players: Hexagonal chess, Four-player chess and Capablanca chess.
  • Regional relatives: Shogi, Xiangqi and Makruk.
• The quantum rules on every board: split, merge, Measure and ordinary moves; "land = roll, pass = link", drops
  included; kings, pawns and the pieces a variant names always solid; castling and en passant only when they are
  certain; a roll whenever the game would end in some possibilities but not in others; a budget of 8 arrangements per
  side.
• The classic end rules in the two-player variants with a king and one move per turn: capture the king instead of
  check, "your king cannot escape", and the bare-kings and 50-move draws, which wait while a king can be captured for
  certain; a variant with its own goal keeps it.
• Computer player for every variant with three levels (Easy, Normal and Hard), running in your browser and keeping
  the board responsive while it thinks. It plays the quantum moves too: splits that fork, dodge or block, merges that
  capture and measurements that settle a danger. In the hidden-information variants it sees only what its own side
  may see.
• Pass & play for two players, or four in Bughouse and Four-player chess, on one device; against the computer you
  take one seat and the computer plays all the others. In Kriegspiel and Fog of war each player sees only their own
  view: a hand-over screen covers the board between turns, and the whole board is revealed when the game ends.
• Variant screens: Chess variants in the navigation and on the home page, with the catalogue by category and
  your games on this device; a New game dialog for the opponent, level, side and the variant's options; a game screen
  for any board shape with the variant's rules next to the shared quantum rules, pieces in hand, the odds of every roll
  before you confirm, a numbered move list, and undo that never rolls a result again.
• Phones and tablets: large boards zoom with the buttons, a pinch or Ctrl + wheel and pan with a finger; 4D chess,
  Bughouse and 5D chess open on the boards you play, and the move controls stay at the bottom of the screen.
• Languages: the variants are in English, Dutch, German and French, like the rest of the app.
