0.20.2

Release 0.20.2

Summary

• Lobby: a table with players closes again, now an hour after it was created instead of the old 5 minutes; a table whose game is starting never closes, and an unjoined one still closes after 5 minutes. Its players see a "table closed" notice instead of a reconnect that ends in "This table no longer exists".

Features

• feat: expire lobby rooms an hour after creation with a notice (a979111)

Maintenance

• chore: set version to 0.20.2 (81f7ea5)
• chore: bump version to 0.21.0 (25f8dce)

0.20.1

Release 0.20.1

Summary

• Game client: opponents' hands and melds draw each tile's edge and shadow per tile instead of through a group filter, fixing misplaced depth on the top seat in Firefox on macOS; the opening screen's OK no longer reserves the width of the long waiting text and shows a short "Waiting…" once pressed; a riichi offer now plays the decision chime like call offers.
• Infrastructure: the deploy notes state that a spot-deploy that goes through interrupted no game.

Features

• feat: chime for a v2 riichi offer like a call offer (d89418b)

Bug Fixes

• bug: draw v2 opponent tiles' edge and shadow per tile, not by filter (2933511)
• bug: shrink the v2 opening screen's OK to a short waiting label (529fc4e)

Maintenance

• chore: set version to 0.20.1 (141dce4)
• chore: note that a passing deploy interrupted no game (310c27d)
• chore: bump version to 0.21.0 (2a9cfe5)

0.20.0

Release 0.20.0

Summary

• Decisions: every chi and kan is its own one-press button (no second tile-choice step), and all decision controls are flat boxes of one height, coloured by kind; a riichi hand's forced discard no longer shows a timer.
• Keyboard: the board can be played from the keyboard — digits press decisions, Esc/right-click pass or discard the drawn tile, arrows move between tiles — with optional key hints and a Controls help panel; focus no longer gets lost between screens.
• Settings menu: new rows for leaving the game (and back to the lobby in a replay), connection ping, corner indices on tiles, the wind letters' script per language and keeping Auto win between rounds; a click that closes the menu now also plays the tile under it.
• Replay: controls rebuilt around the viewer's own turns (own-turn, step and round moves with keys), seat views from the chrome and the opening seating, greyed tsumogiri discards, and a replay link without a seat opens at the logged-in player's own seat.
• Board: round results wait 1.5s and hide while pressed so the final board can be read; live nameplates are plain hover badges; the furiten mark scales with the badge text; centre text is unselectable.
• Protocol: an app-level PING/pong lets the client time its round trip; the game endpoint answers it before routing, without touching a session.
• Fixes: a closed kan's red five stays face up; opponent backs lose a stray beige band; the room page, the opening seating and the settings menu no longer jump as their contents arrive.
• Storybook: one page for every decision, split tiles and system pages, a compact melds page with red fives, and new seat scenarios for the call options.

Features

• feat: hold v2 round results 1.5s and show the board while pressed (7781961)
• feat: add a back-to-lobby row to the v2 replay's settings menu (ca16b91)
• feat: make the v2 centre's text unselectable (d083fed)

0.19.0

Release 0.19.0

Summary

• Rules: Aligned scoring and game end with Tenhou's rules: renhou and kiriage mangan are off, and the all-last dealer ends the game when first with the winning score threshold (agariyame and tenpaiyame), with a repeat taking priority over the threshold in the extension rounds.
• Payments: Pao now covers the whole hand, stacked yakuman included. In a double ron the honba bonus goes only to the winner closest to the discarder.
• Kan: A kan is allowed with one live tile left in the wall, and a replacement tile drawn as the wall empties is rinshan, never haitei. Deferred kan dora is revealed at the replacement discard, so a ron on that discard counts it and its ura.
• Game client: A double right-click no longer discards the next draw after answering a call. Phone side melds stay on the board by closing the gaps between them, and the top badge holds a bot's whole name.
• Infrastructure: A deploy now refuses to start while the game server has a started or pending game.
• Docs: The ruleset states what Ronin does, spells out how final points are rounded, and drops an unsourced claim about JPML karaten.

Features

• feat: end the game when the all-last dealer stays in first place (527c7e8)

Bug Fixes

• bug: make pao cover the whole hand, stacked yakuman included (7cf0577)
• bug: reveal deferred kan dora before ron on the replacement discard (22d6a8e)
• bug: pay double ron honba only to the winner closest to the discarder (a848079)
• bug: allow kan with one live tile left in the wall (fb2b7f3)
• bug: disable renhou and keep one rules profile (29eccea)
• bug: score 4 han 30 fu exactly, without kiriage mangan (374f2cf)
• bug: stop a double right-click from also discarding the next draw (4d9935d)
• bug: keep phone side melds on the board and bot names on the top badge (efabb77)

Maintenance

• chore: refine rules doc (6be52d8)
• chore: refuse a deploy while games are live (a9dd8f5)

0.18.0

Release 0.18.0

Summary

• Phone board: the game is playable in a phone browser with its bars shown (iOS 26 Safari, Android Chrome), where it used to fall to a 2px river. The board runs to the screen's bottom edge, the centre is a short, wide panel that leaves the discards more room, and ordinary melds stay on the board on short phones.
• Phone controls: decisions stand in one right-aligned row by the hand, the play switches in a left column, and a finger's first tap lifts a tile while the second discards it. Result panels are centred, with dora and ura on one line on narrow phones.
• Browser and app: a swipe or the Full screen button hides the browser's bars, a swipe down no longer reloads a live game, and the lobby and game install as a phone app.
• Orientation: the upright board is gone. Portrait viewports under 768px wide ask to rotate, in live games and replays; tablets and large windows keep the board.
• Game pacing: turns and calls get 10s of free decision time (was 5s) and result screens 15s (was 10s). The 20s bank and the game start confirmation are unchanged.
• Settings: an animations switch turns off tile motion without changing game timing, and the mouse-only rows are hidden on touch devices.
• Lobby: colors move to the game's teal, and the glows are gone.
• Desktop: switches show full names in a row, and short desktops use the same single decision row as phones.
• Tooling: the visual check covers browser-boxed phones and no longer fails on an empty river or the latest discard's offset. Makefile.local holds a machine's own make targets.

Features

• feat: make the lobby and game installable as a phone app (51d4469)
• feat: move lobby colors to the game's teal and drop the glows (2ca3511)
• feat: add an animations switch to the game settings (4702df5)
• feat: give 10s for turns and calls and 15s for result screens (5082e80)
• feat: make a finger's first tap lift a tile and the second discard it (ca8e23a)
• feat: make replays landscape only and drop the upright board (98bb3a4)
• feat: let phones hide the browser bars by swipe or full screen (aa26547)
• feat: shrink a short phone's centre so its discards can grow (e63608a)

0.17.1

Release 0.17.1

Summary

• Accounts: Usernames are now 3-16 characters and matched in full, so a trailing newline no longer passes. Humans cannot register names reserved for bots (ai followed by a dash or underscore) or anything starting with nanashi, in any letter case, and the register form now shows the translated reserved-name error.
• Bots: New bots must be named ai-<lowercase>. AI seats appear as ai-tsumogiri-N in games and the room seat list, and run-games bots follow the same scheme.

Features

• feat: cap usernames at 16 and reserve the ai- prefix for bots (122d4ff)

Maintenance

• chore: set version to 0.17.1 (8a87543)

0.17.0

Release 0.17.0

Summary

• Game rules: chi is now offered both with and without a held red five, so a hand holding a red and a plain five gets every pairing instead of a single option.
• Game client layout: the own hand is drawn at 1.6 river tiles off phones and grows on phones up to the side strips; desktop chrome scales continuously from regular to large, side name badges use their real lane, and the top badge keeps ordinary names whole.
• Game client stability: own and opponent melds keep their size across draws, sideways tiles stay on their row's baseline, tile edges stay attached during hand reflows, and the round-result panel keeps its size when confirming and stays compact and centred.
• Game client polish: the selected tile lifts clearly above the 5px hover lift, mouse and auto-discards no longer show the keyboard focus ring, game-end actions stay on one row under classic scrollbars, and "Game over" is now "Final results".
• Replay: scrolling the wheel holds each round result briefly instead of halting on it.
• Lobby: new terms of service and privacy policy pages in en, ja and ru, linked from every page footer and the login and register forms; leaving a page no longer flashes a lost connection.
• Infrastructure: deploy host, SSH user and domain now live in a gitignored per-target env file, so the repository can be deployed to other servers without editing tracked files.

Features

• feat: add terms of service and privacy policy pages (8bf0131)
• feat: let v2 round-result tiles grow with the free box off phones (56666da)

0.16.0

Release 0.16.0

Summary

• Lobby sessions: Sessions are now stored in SQLite as hashed tokens, so restarts and deploys no longer log everyone out. Expiry slides: 30 idle days for accounts, 7 for guests, with a 90-day cap.
• Rooms: Waiting rooms stay open while anyone is in them. A lost connection holds the seat for 5 minutes, and the room page reconnects on its own with backoff.
• Security: Guest login is rate-limited per client IP. The engine and the wire now accept only strict integer tile ids, kan actions must name their kan type, and malformed action data raises a game error instead of a raw validation error.
• Rules: A closed kan now prevents the Four Winds abort, and a further kan reveals an earlier kan's deferred dora.
• Performance: Waits, tenpai and riichi discards are computed from native shanten masks. Each draw makes fewer state copies and skips wall re-validation, ron checks run once per discard, a broadcast is encoded once for all recipients (or not at all when nobody receives it), and each connection uses one send-deadline timer. Below-level log calls are dropped cheaply, and finished replays are encoded off the event loop.
• Tooling: make profile-games now reports game server CPU per message and the garbage-collection share of CPU. Deploys use an SSH key file.

Features

• feat: a further kan reveals the earlier kan's deferred dora (d6bef4c)
• feat: a closed kan prevents the Four Winds abort (bb08cca)
• feat: rate-limit guest login per client IP (4f45ceb)
• feat: slide session expiry with idle timeout and 90-day cap (b9f2ca6)
• feat: persist lobby sessions in SQLite with hashed tokens (90eaf12)

0.15.0

Release 0.15.0

Summary

• Gameplay: A Tenhou-style start screen with an OK button holds the first deal until every human seat confirms (or a 10 s timeout), which also unlocks browser sound; AI player turns are paced at 1 s so humans can follow consecutive AI discards. Replays stay unpaced and identical. Bots must now confirm the first deal (GAME_START_CONFIRM).
• Localization: The game client is now translated into English, Japanese and Russian — mahjong terms, play screen, result screens and replay pages — with a language switch in the settings menu that redraws in place and shares the lobby's language cookie. Wording, plurals, list joins and decimals follow each language and the glossary.
• Browser support: Browsers too old to lay out the board (before Chrome/Edge 108, Firefox 128, Safari 16.4) get a notice on the game page and a banner in the lobby instead of a broken board; the notice also works on Safari before 15.4.
• Frontend: The page body follows the visible viewport height, so phones no longer scroll past the board; sound unlocks without navigator.userActivation, retries failed loads and drops late plays instead of bursting a backlog; the language buttons meet the 40 px tap target; the footer version links to its GitHub release.

Features

• feat: link the footer version to its GitHub release (45bedb9)
• feat: language switch in the game client's menu (77f658a)
