+# Usurper Reborn v1.1.13
+
+## Main Street
+
+- **Main Street is laid out in districts.** It shows its places (Dungeons,
+  Inn, Explore, Team Corner, Dark Alley), then Merchant Row, Guild Row,
+  Home & Hearth, Castle Grounds, Status, the Notice Board and, online,
+  the Online hub. Each opens a short screen of its places:
+  - Merchant Row: Weapon, Armor, Magic and Music shops, the Auction House
+  - Guild Row: Healer, Temple, Old Church, Bank, Level Master, Quest Hall
+  - Home & Hearth: Home, Lodging, Love Street
+  - Castle Grounds: Castle, Challenges, Sanctum, and the Settlement once
+    it is founded
+  - Status: Status, Progress, Stats Record, Fame, Good Deeds
+  - Notice Board: News and World Events
+  - Online: Who's Online, Chat, Arena, World Boss, Guilds
+- Every screen shows only the keys it uses, and every key does what it
+  shows. [R] returns to Main Street. The old hidden keys are gone.
+- Places still open at the same levels. A district appears once anything
+  in it opens, and the first visit after a new level names what opened
+  and where ("New in Guild Row: Temple, Old Church, Bank.").
+- [?] on Main Street shows a map of every open place and its keys.
+- Characters from earlier versions are told once that the street was
+  reorganised.
+
+## Combat and the dungeon
+
+- **The XP lines add up.** The world event lines say they are included in
+  the XP gained, one line names the other XP modifiers, and the party
+  share line matches the gain.
+- **Auto-combat drinks a potion at the HP share you choose** (20 to 70
+  percent, default 50), set in the preferences.
+- **Floors 4 to 6 are softened** on the way to full strength at floor 7.
+- **A monster's stun or web follows the same hold rules as PvP:** nothing
+  new lands while one holds, and a hold is followed by a short immunity,
+  so they cannot chain.
+- **The combat status line** shows each effect's turns left, damage per
+  turn for bleeding and poison, the turns a hold costs, and whether Last
+  Stand and Death's Door are ready.
+- **The chest's Search for Traps works.** A trap it finds is disarmed and
+  the chest keeps its treasure.
+- **An invalid choice asks again** in menus and room events instead of
+  sending you back to the room, and a room event is spent only once you
+  choose. Room actions that cannot be used say why.
+- **Keys typed during an online pause are kept** and run next; the online
+  pause says "Press Enter".
+- **The tutorial states the Old God rule:** you may retreat from a god's
+  floor, but you cannot go deeper until the god is defeated or won over.
+- **Equip Best picks for a companion's role:** defence and health for a
+  tank, wisdom, intelligence and mana for a caster, wisdom and mana for a
+  healer.
+
+## Levels
+
+- `/train` takes you to the Level Master from Main Street, or says how to
+  get there. Level 10 is announced.
+
+## NPCs
+
+- **New NPCs no longer get Roman numerals** in their names. A name that
+  is taken gets a surname, and a child whose name is taken gets another
+  first name with the family surname. Existing NPCs keep their names.
+- **NPC memories keep the time they happened** and fade after seven days
+  as intended. Memories older than that when this version first starts
+  are kept and start their seven days then.
+- **Deleting a character clears NPC grudges against it and NPC marriages
+  to it** again.
+
+## The royal court
+
+- **Every treasury and court change is saved in one step,** and a
+  purchase's cost and effect are saved together; your gold changes only
+  once the court's change is saved.
+- **A new king is saved at once,** whether by challenge, siege, an empty
+  throne, abdication, rebellion or ascension.
+- A failed throne challenge keeps the guards and monsters it beat.
+- Guard bonuses that would overflow are refused.
+- Sales tax is credited to the treasury once, not twice.
+- A sales tax set to zero stays zero.
+- Dismissing or promoting a courtier acts on the one chosen, not a
+  namesake.
+- Bail granted by an NPC can be paid at once, and an arrest with no
+  prison record can be pardoned.
+- An orphan who comes of age becomes one new NPC, not a new one every
+  day.
+- Throne challenges face the real king, not a stand-in.
+
+## Other fixes
+
+- Equip Best and every equipment menu take the item you chose, not the
+  first of that name, and gear moved to or from a companion is saved in
+  an order that cannot copy it.
+- Deleting a character keeps mail sent by a living character of the same
+  name.
+- Deleting a player from the web admin page runs the full clean-up.
+
+## Self-hosted servers
+
+- Setups that run one game process per player keep a log of world edits
+  that the world-sim process re-applies, and save NPCs and the court only
+  over the version they loaded. Such setups must run player processes
+  with `--no-worldsim` beside one `--worldsim` process.
+
+## Known and unchanged
+
+- Royal petitions can spend more treasury gold than the treasury holds.
+- A monarch who dies leaves a throne that a restart can restore.
+- An NPC imprisoned in a street encounter is not released online.
+- A very large donation can overflow Crown standing.
+- A retried court change can repeat its news line.
+- A sales-tax write that gives up is logged, not refunded.
+- An admin delete whose game server stops mid-way stays pending, and the
+  web page reports a time-out.
+- On self-hosted setups with one process per player, an NPC created with
+  no ID under a name removed earlier in the same session is not saved.
+
+## Tests
