 ## [Unreleased]
 
+## [0.48.0] — 2026-07-15
+
+### Changed
+
+- **Floating glass tab bar** (touch). The bottom action bar is now a
+  floating translucent pill — Undo, Draw, Hint, and Pause — with a
+  separate round Menu button beside it, hovering above the bottom edge
+  instead of docking to it. Draw stays expanded as the highlighted
+  action; the other buttons reveal their label while held (instantly,
+  with reduce-motion on). Same actions, same behaviour — new clothes.
+  (#186)
+- **Consistent empty, loading, and error screens.** The theme store,
+  leaderboard, and replay list now share one visual language for
+  "nothing here yet", "still loading", and "something went wrong" —
+  each with a next step instead of a dead end. (#184)
+
+### Fixed
+
+- **Hotkeys during drags.** Pressing Undo, New Game, Draw, or a mode
+  key mid-drag no longer fights the card you're holding — game-mutating
+  hotkeys are ignored until the card is dropped. (#185)
+
