 All notable changes to Switchboard Core are documented here.
 
+## [Unreleased] — v0.2.5
+
+### Added
+
+- **Welcome surface**: New core surface shown as fallback. Detects whether
+  extensions exist (shows "Set Default Surface") vs truly empty install
+  (shows "Go to Packages"). Topbar + UserMenu included.
+- **User default surface**: Users can set a personal landing page in
+  Settings > General, overriding the admin-configured global default.
+- **UserMenu in admin topbar**: Replaced Back button with UserMenu,
+  providing consistent surface navigation and eliminating infinite loops.
+- **Package manifest icons**: Added emoji icons to hello-dashboard,
+  icd-test-runner, sdk-test-runner, and team-activity-log manifests.
+- **PoC documentation**: README.md for tasks and schedules packages
+  documenting Proof of Concept status and graduation criteria.
+
+### Changed
+
+- **Default surface resolution**: Priority chain is now
+  user preference → global config → first extension → `/welcome`.
+  User preference read from JWT cookie on unauthenticated `/` route.
+  Correctly resolves `type: "full"` extension packages (not just `type: "surface"`).
+- **User settings General section**: Replaced dead chat fields (Default
+  Model, System Prompt, Max Tokens, Temperature, Show Thinking) with
+  a Default Surface dropdown.
+- **Admin settings**: Removed dead chat sections (System Prompt, Default
+  Model, Policies, Web Search, Auto-Compaction, Memory Extraction).
+- **Roadmap restructured**: Workflows → v0.3.x (includes team roles),
+  Notes → v0.4.0, MVP → v0.5.0. Added settings audit milestones
+  (v0.2.7 admin, v0.2.8 user, v0.2.9 team-admin pass 1).
+- Updated bus doc examples and test labels from `chat.*` to `workflow.*`.
+- Renamed `channel-` prefixed test paths to `test-` in storage tests.
+- Updated doc comments throughout to remove references to gutted surfaces.
+
+### Removed
+
+- **~500 lines of dead CSS**: Orphaned classes for gutted chat, channel,
+  project, notes, editor-chat, sidebar, and router-picker features from
+  `layout.css` and `surfaces.css`.
+- **Dead Go types**: `Grant` struct (persona-era), `CompositeModelKey` func,
+  comment-only stubs for NoteGraph, ProjectChannel, etc.
+- **Dead event code**: `chat.typing.*` / `channel.typing.*` condition in WS
+  subscriber, empty Chat/Channel event route table sections.
+- **Dead test helpers**: `seed_helpers.go` (SeedTestMessage, SeedTestMessages,
+  SeedTestCursor — all callerless).
+- **Stale template refs**: CSS link tags for non-existent `sw-chat-pane.css`,
+  `sw-notes-pane.css`, `chat.css`. Orphaned `chat-pane.html` component.
+- **Vestigial guards**: `"chat"` surface checks in `IsSurfaceEnabled()` and
+  `DisablePackage()` (chat is no longer a surface).
+- **Dead settings UI**: Chat defaults from user settings, System Prompt /
+  Default Model / Policies / Web Search / Compaction / Memory from admin.
+- Unused `fmt.Sprintf` references in team stores.
