 All notable changes to Chat Switchboard.
 
+## [0.19.0] — 2026-02-28
+
+### Added
+- **Projects / Workspaces.** Organizational containers that group related
+  conversations, knowledge bases, and notes into a single workspace.
+  Projects provide a scope-aware organizational layer above individual
+  channels, with support for personal, team, and global visibility.
+- **Project data model.** Four new tables: `projects` (with scope, owner,
+  team, color, icon, settings JSONB), `project_channels` (ordered
+  membership with UNIQUE constraint), `project_knowledge_bases` (with
+  auto_search flag), and `project_notes`. Channels gain a denormalized
+  `project_id` FK for efficient filtering.
+- **Project API.** 17 new endpoints under `/api/v1/projects`: full CRUD,
+  channel add/remove/list/reorder, KB add/remove/list, note
+  add/remove/list. Access checks enforce owner-or-team-member visibility
+  with owner-only delete.
+- **Project KB resolution.** Knowledge bases bound to a project are
+  automatically available to all channels within that project. Resolution
+  chain extended: Persona KBs → **Project KBs** → Channel KBs →
+  Personal KBs. Both `BuildKBHint` (system prompt injection) and
+  `kbsearch` (tool-time retrieval) updated.
+- **Note auto-association.** Notes created from a channel that belongs to
+  a project are automatically added to that project's note collection.
+- **Sidebar project groups.** Projects appear as collapsible groups in the
+  sidebar above the existing time-based "Recent" section. Each group shows
+  a color dot, chat count, and an options menu (⋯) for rename, color
+  picker, and delete.
+- **Drag-and-drop.** Drag chat items between project groups or back to
+  Recent. Visual feedback with outline and background highlight on valid
+  drop targets.
+- **Right-click context menu.** Right-click any chat to move it to a
+  project, remove it from its current project, or create a new project
+  and assign in one step.
+- **New Project button.** Added to the New Chat split-button dropdown for
+  quick project creation.
+- **Channel project_id filter.** `GET /api/v1/channels` accepts
+  `?project_id=<uuid>` to filter by project, or `?project_id=none` for
+  unassigned channels. Response includes `project_id` field.
+
+### Changed
+- `renderChatList()` rewritten to support project grouping while
+  preserving the original time-based layout when no projects exist.
+  Chat items now include `draggable`, `oncontextmenu`, and drag event
+  handlers.
+- Channel response struct, SELECT queries, and scan calls updated across
+  `ListChannels`, `GetChannel`, and `CreateChannel` (both Postgres and
+  SQLite paths) to include `project_id`.
+- `resource_grants` CHECK constraint extended to include `'project'` as a
+  valid resource type.
+- `db-validate.sh` updated: former "Dropped tables" assertions for
+  `projects` and `project_channels` replaced with positive checks for all
+  four project tables plus `channels.project_id` column check.
+- Test helper truncation list updated with project junction tables.
+
+### Fixed
+- **JSON corruption defense** (hotfix carry-forward from 0.18.2):
+  `SafeJSON` wrapper with `scanJSON` and `scanTags` hardened helpers that
+  replace bare `json.RawMessage` / `pq.Array` scanning. Prevents
+  `encoding/json: invalid character` panics from NULL or empty columns.
+- **Service worker** (hotfix carry-forward): `chrome-extension://` URL
+  filtering to avoid opaque response cache errors.
+
