 All notable changes to the independently versioned Toolbox SDK packages are
 recorded here. The packages currently share one release version.

+## 0.3.0 — 2026-09-02
+
+### Added
+
+- Runtime-validated manifest I/O and progressive browser-capability profiles.
+- Bounded, same-origin, target-routed, expiring, one-time artifact handoffs
+  through IndexedDB, with versioned operation evidence and opaque tokens.
+
+### Security
+
+- Reject unsafe artifact names, malformed descriptors, oversized evidence,
+  excessive file counts and cross-origin handoff destinations before storage or
+  navigation.
+- Document the origin-wide IndexedDB trust boundary explicitly: target app ids
+  route transfers but cannot authorize mutually untrusted same-origin code.
+
+## 0.2.3 — 2026-07-27
+
+### Changed
+
+- Moved the canonical repository, schema identifiers, examples, and source
+  metadata to the `lotobo` (LocalToolBox) Gitea organization.
+- Moved publication of all three packages to the `lotobo` Gitea npm registry.
+
+## 0.2.2 — 2026-07-23
+
+### Added
+
+- `ToolboxPersonalizePanel` for the portal-style personalization heading,
+  storage warning, appearance picker, and portal extension content.
+
+### Changed
+
+- The invariant top row now fixes the Toolbox brand/home at the far left and
+  Help, source, Apps, and Personalize at the far right in that order while the
+  text identity remains geometrically centered.
+- Default app personalization now matches the central portal's panel styling;
+  portal-only catalogue counts and import/export actions remain extensible
+  content.
+
+## 0.2.1 — 2026-07-23
+
+### Added
+
+- `ToolboxHeader.personalizeContent` for custom preferences inside the shared
+  controlled popover and `brandIconUrl` for a portal favicon with an inline
+  Toolbox cube fallback.
+- Accessible, mutually exclusive Personalize and Apps popovers that close on
+  Escape, outside interaction, and link selection.
+
+### Changed
+
+- The invariant top row now orders Personalize, Apps, source, and Help on the
+  left, keeps the text-only app identity geometrically centered, and fixes the
+  Toolbox brand/home block at the far right.
+- Personalize and Apps keep visible desktop labels, become compact icon controls
+  responsively without losing accessible names, and source and Help remain
+  present at every supported width.
+- `AppShell` now renders version, privacy, manifest actions, and legacy app
+  actions in a standard footer instead of changing the top-row geometry.
+- `iconUrl`, `leadingActions`, and `metadata` remain accepted for source
+  compatibility but are deprecated for the fixed header design.
+
+## 0.2.0 — 2026-07-22
+
+### Added
+
+- A reusable, genuinely centered `ToolboxHeader` with standard Help, Gitea
+  source, Personalize, and Apps controls.
+- Shared versioned browser preferences in `@add-ideas/toolbox-contract`, using
+  the portal's existing storage key so light, dark, and system mode follow the
+  user between same-origin Toolbox apps.
+
+### Changed
+
+- `AppShell` now uses the common top bar in both connected and standalone mode,
+  derives its source link from manifest metadata, and offers app switching from
+  a consistent Apps menu.
+- Explicit relative `manifestUrl` values now resolve against the deployed page
+  URL, including nested-path deployments.

+The package also owns the versioned same-origin browser preference contract. Use
+`readToolboxPreferences()` and `writeToolboxPreferences()` to share pinned apps,
+ordering, visibility, and light/dark/system mode with the Toolbox portal.
+
+Applications can advertise accepted and produced formats through the optional
+`io` manifest profile, and required or optional browser features through
+`capabilities`. These fields are runtime validated while remaining compatible
+with existing v1 manifests. When the capability profile is present, a manifest
+that sets `requirements.workers` to `true` must also list `"workers"` in
+`capabilities.required`; progressive worker enhancements belong in
+`capabilities.optional` with the requirement set to `false`. Legacy v1 manifests
+without `capabilities` remain valid.
+
+The package also provides an explicit local artifact handoff. A sender stores
+one or more bounded `Blob` objects in same-origin IndexedDB with a
+cryptographic, short-lived token and a target routing label.
+`createToolboxTransferUrl()` places only the opaque token in the target URL;
+`consumeToolboxTransfer()` atomically consumes it once. No file bytes are put in
+a URL, uploaded, or persisted after consumption. Destination URLs must remain
+same-origin, and descriptors, evidence, file counts, total bytes, and lifetimes
+are validated and bounded before storage.
+
+All code on one origin is inside the trust boundary: same-origin scripts can
+open IndexedDB without using this API, so `targetAppId` is not authorization.
+Host mutually untrusted apps on distinct origins; they deliberately cannot use
+this transfer mechanism.
