## 1.7.0 (2026-05-21)
> **New: Pro mode (experimental).** Opt-in tabbed multi-pane interface for power users. Open multiple mail, calendar, contacts, and file views side-by-side, drag tabs to reorder or split panes at the edges, and work across all logged-in accounts in one shell - cross-account email moves, a unified inbox with search, account-split calendar/contacts/files sidebars, and a per-account "From" dropdown in the composer. Enable from Settings → Appearance; the `proInterface` preference is per-device and not synced.
### Breaking Changes
- **Plugins**: Plugins now run inside a null-origin iframe sandbox and talk to the host over a postMessage RPC bridge. The in-process plugin runtime is gone; the bundled in-tree plugins have been migrated. Third-party plugins built against the old in-process API need to be ported to the sandboxed runtime.
- **Plugins**: Server-managed bundles must be Ed25519-signed by the host and approved by an admin before they load. The host public key is served from `/api/plugin-signing-pubkey` and each bundle response carries the signature in the `X-Bundle-Signature` header. User-uploaded bundles still load unsigned, but managed marketplace and dev-folder bundles do not.
- **Plugins**: `bundleHash` is now a full SHA-256 over the bundle. Legacy short hashes are migrated on first load; any out-of-band tooling that pinned the old hash format needs to be updated.
### Features
- **Pro**: Tabbed shell with drag-to-reorder, drag-to-edge to split, side-by-side panes, and pane-aware responsive layout with a scoped sidebar overlay
- **Pro**: Auto-redirect to the Pro shell when Pro mode is on; `proInterface` is kept per-device instead of syncing
- **Pro**: Multi-account mail sidebar with client routing and a per-account mailbox cache
- **Pro**: Unified mailbox always visible, with full-text search
- **Pro**: Cross-account email moves
- **Pro**: Multi-account calendar sidebar split into owned vs shared per account

## 1.6.4 (2026-05-11)
### Web Setup Wizard
First-launch web setup wizard. New installs no longer need to hand-edit `.env.local` - point a browser at the container and the wizard probes the JMAP server(s), configures OAuth/OIDC, generates the session secret, accepts branding uploads, and provisions the initial admin password. Admin storage is now split into `ADMIN_CONFIG_DIR` (operator-authored, mountable read-only after setup) and `ADMIN_STATE_DIR` (runtime audit log and login timestamps); the legacy `ADMIN_DATA_DIR` keeps working for existing installs.
