 # Changelog
 
+# v0.2.58
+
+The wiki gains a proper manual, and the app starts teaching itself. New Documentation pages explain how each system works in plain language, and major pages can walk you through themselves on first visit.
+
+### Features
+
+- **Documentation**: a new Documentation category in the wiki collects in-depth guides for logistics and storage rules, banking, the market and its negotiation flow, shipments, base management, and the map. Everyone can read them; only admins and developers can write them. If a page looks out of date, contact the staff team.
+- **Guided tours**: major pages now greet first-time visitors with a short walkthrough that highlights the important parts of the screen. Steps respect your access, so you only see what you can actually use. Replay the current page's tour any time from the header help icon.
+- **Skip all tours**: the tour window has a "Skip all tours on this device" action, and the Account page holds an "Auto-start page tours" toggle, so tours are opt-in rather than opt-out. Replaying a tour from the header always stays available.
+
+### Improvements
+
+- **Documentation authorship**: seeded Documentation pages show "System" as their author instead of "Unknown editor".
+- **Wiki callouts**: the note and warning icons sit vertically centered in their callout boxes instead of floating above the text line.

+# v0.2.57
+
+Op prep gets a queue: claim the mission role you want before op night. Map editing also becomes permission-based piece by piece, so mapping rights can be handed out without giving away full control.
+
+### Features
+
+- **Mission role sign-ups**: you can now queue for a specific role on an upcoming mission. Meeting the role's minimum rank and MOS lets you claim one of its slots first come, first served, and everyone else waits in a numbered line. When a slot holder changes their RSVP to no or withdraws, the next person in line moves up automatically and gets a notification. Role promotions can be muted in your notification settings, and staff can still remove sign-ups.
+- **Role slots and descriptions**: mission roles now declare how many slots they offer, and a role can carry a formatted description with headings, lists, and links, shown under the role name in the roles table and the sign-up panel.
+
+### Improvements
+
+- **Map permissions**: drawing roads, zones, and resource nodes, and placing structures, are now separate permissions rather than one blanket map grant. Staff can give mapping rights to more people without handing over the rest of the map tools.
+- **AI compose**: drafts now come from a larger Gemma model, and replies that arrive wrapped in code fences get cleaned up, so fields fill with prose instead of raw JSON.
+
+### Breaking Changes
+
+- Map editing was re-cut into four permissions: Author Roads, Author Zones, Author Nodes, and Place Structures. A role that could edit maps before needs the relevant ones granted again in the admin panel before its members can edit, and structure placement keeps requiring the logistics qualification on top.
