- Email translation moves from LibreTranslate to our own translator
service (translator/): Mozilla's Firefox Translations models on the
Bergamot engine, fastText language detection (176 languages). Polish,
English, German, French, Spanish and Italian on first start (~350 MB
instead of ~10 GB); Admin panel > Email translation installs and
removes languages. Built and pushed as the `translator` image.
- Every message is translated paragraph by paragraph as plain text;
names travel with their sentence and are kept only where the model
changed them; a sentence start the model copied ("Enclosed") is tried
again in lower case; list markers are not sent
- The Translate button shows only for installed languages
- New logo: favicon, app/maskable/iPhone icons, notification badge,
email logo and calendar copy regenerated; BIMI logo rebuilt in SVG
Tiny PS with its gradients; masks render in browsers
- Launch screen background is the app's dark grey

The webmail is now a PWA: web app manifest, icons (any + maskable, a status-bar
badge), theme-coloured title bar following the chosen theme, and an app-icon
badge with the unread Inbox count. The service worker is always installed;
offline access is on only when it is registered as /sw.js?offline=1, so
turning it on or off is an update that applies at once.
Notifications (Settings → Accounts → Notifications, per device) use Web Push.
Encryption (RFC 8291) and VAPID signing (RFC 8292) are implemented in
app/push/webpush.py — pywebpush needs a newer cryptography than we pin — and
checked against the RFC's worked example. The server makes its key pair on
first use (private half encrypted with MASTER_KEY). New mail found by the live
sync in an Inbox enqueues a job 5 s later that tells the user's devices about
messages still unread there, under 2 hours old and not from the user; more
than three become one "N new messages". A subscription belongs to the session
it was made under: signed out or revoked, nothing more is sent there. Endpoints
are limited to the known push services (no SSRF). Nothing shows while the app
is in front (except on Apple, which requires it). Tested with real pushes
through Google's service in Chromium and Opera.
The mobile drawer gets "Install app": Chrome's own install dialog where the
browser offers one, else short steps for iPhone/iPad, Opera and Firefox, with
"Don't show this again". docs/nas-install.md §5.3 covers installing,
notifications, Public URL and a later Android app (TWA).
Migration 0022: push_subscriptions, app_settings.vapid_*.
