 ## [Unreleased]
 
+## [0.44.0] — 2026-07-13
+
+### Added
+
+- **Home is now a real home (menu redesign Phase B).** The mode picker became
+  a hierarchy: a **Continue** card (mode · elapsed · score) appears while a
+  game is in progress and returns to the table; a hero **New Game** button
+  replays your last mode with the current deal options in one tap; deal
+  options (draw 1/3, a new **winnable-only** toggle, difficulty tiers) moved
+  into a disclosure under the hero; the six modes sit in a compact symmetric
+  2×3 grid with descriptions on wide screens; and the stats strip moved to
+  the bottom. Wide viewports (desktop, unfolded foldables) get a two-pane
+  layout — launch surfaces left, Continue/daily/stats right. Cancel is now
+  **Back to table** and only appears while a live game exists. (#175)
+
+### Fixed
+
+- **Save files are self-contained (schema v6).** Like replays in 0.43.3, a
+  saved game now stores the dealt board via the upstream session serializers
+  instead of re-dealing from the seed on load; v4/v5 saves still load through
+  the legacy path and rewrite as v6 on next save. (#171)
+
+### Internal
+
+- **CI is ~9× faster.** Root-caused why the actions cache never restored on
+  the host-executor runner (per-run workdir paths poisoned the cache version
+  hash); the test workflow now uses a persistent on-runner target dir, and a
+  seconds-long `fmt` gate fails formatting mistakes before the build. Warm
+  full-gate runs: 4m29s, down from ~40 min. (#176)
+
+## [0.43.3] — 2026-07-10
+
+### Fixed
+
+- **Replays are now self-contained (schema v4).** A replay stores the dealt
+  board itself via the upstream `card_game` session serializers instead of
+  re-dealing from the seed at playback time, so replays survive RNG and
+  upstream upgrades that change the seed→deal mapping — the failure that had
+  silently broken every stored replay. The web player and web game now
+  exchange the full payload through the wasm layer (the old JS path hardcoded
+  `schema_version: 2`, uploaded empty move lists, and corrupted u64 seeds via
+  `Math.round`), and the replay viewer reports unplayable old-format replays
+  in the caption instead of dying silently. Pre-v4 replays are rejected by a
+  version gate; local histories repopulate with new wins. (#170)
+- **Difficulty-mode wins can upload.** The server's replay `mode` validation
+  now accepts data-carrying `GameMode` variants (previously a 400). (#170)
+
