+- Better UI, settings, controls. *Done so far:* volume sliders, tips and
+  update settings in the pause menu; `Q` drops items; `K`/`M` put any bag row
+  on the 1-8 keys (0.3.0).
+- Audio, music, weather. *Done (0.2.0-0.2.1):* mood music (calm, night,
+  storm, danger, boss) that crossfades with what's happening, ambience (CC0
+  birdsong, crickets, owls, fire), sound effects for every action (Kenney
+  CC0 plus synthesised), creature voices, Old Tam's spoken lines (Kokoro).
+  Sources and licences: `assets/audio/CREDITS.md`; tools in `tools/audio/`
+  and `tools/voice/`.
+- Help: the player guide on the download site (`tools/site/`), written
+  sections plus item, recipe, creature, fish and server-setting tables made
+  from the game's own data each build. The trailer (`tools/trailer/`).

   signed, not notarised) and a Windows x86_64 .exe + .pck (unsigned), zipped
