**About said "not detected".** Generation was only worked out from the reply to
a registry method, which we never send to a server that does not advertise
urn:stalwart:jmap — every 0.16 build does, and nothing older knows the
capability at all, so its absence is already the answer. Say so, instead of
shrugging. A session with no capabilities at all stays unknown, which is a
different thing from old.
**The caret jumped out of the OTP field after one digit.** Dialog's autofocus
effect listed onClose in its dependencies, and every caller passes an inline
arrow, so each keystroke in a dialog holding state tore the effect down, set it
up again, and refocused the first field — which in the disable-2FA dialog is
the password. Keep the handler in a ref so the effect depends only on `open`.
This was a bug in the shared dialog rather than in one screen; every dialog
with more than one field had it.
The test for it fails against the old dependency array, not just passes
against the new one.
The account locale came from `x:Account/get`, which needs `sysAccountGet` — a
permission the built-in `user` role is not given, so the setting silently fell
back to the browser locale for exactly the people most likely to have set it.
Stalwart 0.16 carries the same field on `x:AccountSettings`, whose
`sysAccountSettingsGet` *is* part of that role. Both are now asked for in one
request and whichever answers wins, so admins and older servers keep working.
That pair of replies also says which generation we are talking to: only 0.16+
can parse the method name at all. About now reports that, plus the edition
from /api/account where the server offers it. It does not report a version
number because Stalwart does not publish one to clients — it hardcodes a
public "1.0.0" and keeps the real version to its SMTP internals — so the
screen says what was actually detected rather than inventing precision.
Also adds a light/dark toggle to the top bar, left of the settings button. The
stored setting is three-way, so the button acts on the theme actually on
screen: whichever one you see, a click gives you the other. Choosing "match
system" again stays in Settings › Appearance, where a three-way choice belongs.
Every user-visible date now goes through web/src/lib/datetime.ts, driven by
three settings (Settings > General > Locale):
- Language & region: automatic, or any of the 618 locales CLDR has data for,
each named in its own language and script (web/src/lib/locales.ts, generated
by probing Intl over the subtag space).
- Date format: automatic (locale order), 22.11.2025, 22/11/2025, 11/22/2025,
or ISO 8601 2025-11-22.
- Time format: automatic (locale), 24-hour, or 12-hour.
Automatic takes the locale Stalwart has for the account, read best-effort at
login via x:Account/get (urn:stalwart:jmap) and passed to the client in the
session; servers without the capability, or that deny sysAccountGet to a
regular user, fall back to the browser locale. POSIX forms are normalised
(de_DE.UTF-8 -> de-DE) and script modifiers kept (sr_RS@latin -> sr-Latn-RS,
uz_UZ@cyrillic -> uz-Cyrl-UZ), while dialect/variant/currency modifiers are
dropped and a script the locale already implies is not appended.
Numerals follow the locale (22.11.2025 renders as Arabic-Indic digits under
ar-EG); ISO 8601 is the exception and pins date and clock to Latin digits so
one line never mixes digit systems.
Rewired: message list and headers, quoted reply headers, calendar (titles,
weekday and hour gutters, mini calendar, agenda, popovers, invite cards,
free/busy), contacts, files, sessions. No raw toLocale*String date calls are
left in web/src.
Native <input type="datetime-local"> pickers always follow the browser locale
and cannot be restyled by a page, so the out-of-office fields echo the entered
instant in the chosen format underneath.
Also: month-grid day labels no longer wrap when they hold a date, and the mock
server serves x:Account/get (MOCK_LOCALE, default en_US).
