App Suite UI

8.51.9 - 2026-10-14

Fixed

  • "This folder is empty" is not shown for an empty mail folder b9da5c7b7
  • Hovering a list row shows nothing in dark mode 1463df57d
    • Fixed rows in Mail, Calendar and Drive not responding to the mouse in dark mode
  • Selected rows paint their text in page colors, not the selection's e220926ae
    • Fixed the date and message preview disappearing in a selected mail row on phones
    • Fixed unreadable text in selected rows wherever a theme gives the selection its own color
    • Fixed Drive's file type icon keeping the page's color on a selected row
    • Fixed a tapped row keeping a color of its own on phones, where there is no hover
    • Fixed a selected row changing color when the mail list takes focus on an iPhone
    • Fixed part of a row changing color on selection on phones, the date and preview lifting while the sender and subject stayed as they were
    • Fixed hovering a selected row washing its color out instead of deepening it
    • Deployment themes can now restyle a selected row's secondary text and its checkbox

8.51.8 - 2026-10-12

Fixed

  • A date format stored by 8.46/8.47 breaks date handling 71ff933ba
    • Regional settings saved in 8.46/8.47 persisted the date format with CLDR's standalone month, e.g. LL/dd/yyyy. Tempo reads the L family as its own presets and rejects such a pattern
    • core/locale now rewrites L to M where it derives the locale data and repairs the stored value on startup
    • configure() is retried without the custom formats, so a bad pattern cannot cost the timezone again
  • A forged message showed the sender's verified badge ff998a75c
    • Fixed a message that fails sender authentication showing the verified-sender badge of the domain it claims to come from, which is the case the badge exists to distinguish
  • A quoted literal in a custom format is read as a preset token 6af8057f2
    • A custom date or time format containing quoted literal text, e.g. "MM/dd/yyyy 'LT'", was rejected as though the literal were a format token, which also discarded the configured locale, timezone and week numbering
    • The check now ignores quoted text, which CLDR treats as literal
  • BIMI logos never appeared for senders on a long TLD e752c9eb2
    • Verified brand logos (BIMI) now appear for senders whose domain ends in a TLD longer than six letters, such as .technology, .photography or .international, and for internationalized TLDs. Previously the logo was silently never shown for any of them.
  • BIMI logos never appeared with Group by conversation enabled 4992db8ab
    • Fixed verified sender logos (BIMI) not appearing in the message list while "Group by conversation" is enabled
  • Ctrl+Enter saves without the value of the field it was pressed in 30416cc97
  • Deleting the calendar you have open reports "Such a folder does not exist" b4ddc8d56
  • Dialogs opened from a mobile window lose their typed input 1b1742a1d
  • Keep the Send button visible after adding a recipient on smartphones (ASB-253)
  • Resolve invalid user timezones from a single source of truth 44232dfce
    • An invalid timezone in a user's configuration falls back to the local timezone instead of leaving dates unresolved
    • An unsupported favorite timezone no longer breaks the calendar settings pane
  • Signature designer e2e test fails when the middleware normalizes tel links 66ad49e2e
  • The setup wizard moves focus away while you type b7615454a
  • Use the right role for Drive's storage entries in Quick Settings 827670cbf
    • "Add storage account" and "Manage Shares" in Drive's Quick Settings are no longer announced as tree items; they carry the button role like every other action in the panel, which also fixes the axe violation in the Drive a11y tests
  • The "display name" is not used to display names (ASB-246)
    • Deployments that maintain display names centrally - an oxDisplayName mapped from LDAP, for example - can now have those names shown throughout App Suite, instead of names composed from first and last name
    • Switched on per deployment with the "preferDisplayName" feature toggle, so everyone in an organization sees the same names; the name format setting then only decides how contacts without a display name are composed
    • Contact lists, address pickers and search are ordered by the display name as well, so what is shown and what a list is sorted by stay in step

8.51.7 - 2026-10-02

Fixed

  • Compose font sizes use points again, instead of pixels c491a3dab
    • Compose font sizes are shown in points again. The switch to pixels in 8.51 came out of making the font settings clearer, but we underestimated how much people go by the number rather than the unit. The familiar sizes exist in both lists, so the same number produced noticeably smaller text than before
    • Existing font size settings are converted back automatically. The earlier conversion had merged some sizes into one, so where the original is no longer recoverable the closest match is restored and anyone who had picked a specific size may want to confirm it once
    • The list of sizes gained 9pt, which closes the wide gap between 8pt and 10pt, plus 48pt and 72pt for larger headlines

8.51.6 - 2026-10-01

Fixed

  • A phone set to "Use system setting" loses its theme e2e8efb32
    • Fixed the theme on phones set to "Use system setting", which lost its colors and left the browser's title bar white while a dark theme was shown
    • Fixed custom themes not being applied on phones
  • Accent color handling in the dark theme and auto dark mode a35bb1413
    • A dark theme's accent color, including one set by configuration, now applies when auto dark mode switches to it, instead of the light theme's
    • An accent color the user picked still survives that switch, unless the theme fixes its own
    • Turning auto dark mode on or off no longer resets the accent color to the theme's default
    • Selecting several rows in dark mode now shows them all in the accent color, rather than the focused one in color and the rest in grey
    • Hovering a selected row in dark mode now lightens it slightly instead of making it darker than the rows around it
  • Complete the background ramp so dark-mode fixes can land 5bb854837
    • Hovering a selected row in dark mode no longer flashes a near-white background
  • Dark mode in the account services list and the scheduling view 12ddc4aae
    • The service names and generic icons in the "Add storage account" dialog are legible in dark mode again, instead of being drawn light on white
    • Appointments in the scheduling view now use the same colors as the calendar shows them in, in both light and dark appearance
    • The grid lines, separators and weekend labels in the scheduling view follow the theme, instead of a fixed set that left the faintest line the most prominent one in dark mode and the strongest one invisible
  • Day labels and the hour scale in the scheduling view 1853c1274
    • The day labels in the scheduling view no longer lose the space between the weekday and the date after navigating to another week
    • The hour scale in the scheduling view reads "8 AM" rather than "08:00 AM" in locales that use a 12-hour clock
  • E2e test "Create recurring appointments with one participant" (broken on certain dates)
  • Give checkboxes and radios one set of colours across the themes fd2d1ecb8
    • Unchecked checkboxes are no longer drawn as a white square regardless of the theme, which was most visible in dark mode
    • Checkboxes in mail, calendar and Drive now match the ones in contacts and tasks, and themes can restyle both together
  • Missing and hard-to-see focus indicators, mostly in dark mode 92bccb4b4
    • Fixed several focus glitches: button labels that were nearly invisible on hover in dark mode, focus rings showing up after a mouse click, and weekday buttons in the calendar side panel with no visible keyboard focus
    • The keyboard focus indicator now follows the theme's accent color instead of the browser's default blue
  • Task status badges glare in dark mode, and overdue is not a warning 22db7deda
    • Task status badges no longer glare in dark mode
    • Overdue tasks are marked in red rather than pink
  • Task titles break in list view, sidepanel, and on mobile when show in calendars (ASB-141)
    • Fixed task titles breaking across two lines in the calendar list view, on mobile, and in the calendar sidepanel when tasks are shown in the calendar
  • Theme the checkboxes in the IMAP subscription dialog 90e490133
    • The checkboxes in the IMAP subscription dialog now follow the chosen accent color and the dark theme, instead of being drawn by the browser
  • Very long attendee names cause the calendar edit window to scroll (ASB-267)

8.51.5 - 2026-09-09

Fixed

  • A configured SystemV timezone is not resolved (ASB-134)
    • Before, a configured timezone from the older SystemV set (for example SystemV/CST6) was not translated to a supported one at startup. Dates and times were then shown in the wrong timezone, on some browsers the timezone could not be applied at all, and moving an appointment could store an unusable timezone on the server
    • Such a timezone is now resolved to its supported equivalent while the configuration is loaded, so it is applied correctly on startup (cherry picked from commit c6fdd728a2f597e42f095a9a022aeea77bf2bde6)
  • Signature preview freezes on a long   run (ASB-151)
    • Fixed a freeze of the Email settings page caused by a signature containing a long run of non-breaking spaces, as produced by quoted text in some mail clients
    • The same freeze affected the Templates settings page (cherry picked from commit bf6309ae0d63fd52e7c9444ebee9f2df9379eaaf)

8.51.4 - 2026-09-09

Fixed

  • Appsuite: slow performance in deputy handling (ASB-132)

8.51.3 - 2026-08-06

Fixed

  • Blank UI on some browsers without native Temporal (support#1626)

8.51.2 - 2026-07-31

Fixed

  • Background images in viewer are not rendered after pdfjs-dist upgrade (fcv-267)
  • Enterprise contact picker when contact IDs contain spaces fc55619d2

8.51.1 - 2026-07-17

Added

  • Translation updates for cs_CZ, da_DK, de_DE, el_GR, en_GB, es_ES, es_MX, fi_FI, fr_CA, fr_FR, hu_HU, it_IT, ja_JP, lv_LV, nl_NL, pl_PL, pt_BR, ro_RO, ru_RU, sk_SK, sv_SE, tr_TR, zh_CN, zh_TW 0bc980e1e

Changed

  • Refresh the folder tree per account so large accounts don't freeze the UI (appsuite/support#1522)
    • Opening or refreshing a mail account with a very large number of folders (e.g. a shared account with 1000+ folders) no longer freezes the UI; the folder tree is now refreshed per account, in the background, in chunks
    • Folder actions (empty, restore, delete) now refresh only the affected account instead of reloading every account

Fixed

  • Antiphishing plugin doesn't work with 8.51 (support#1545)
  • Enable mail D&D (with app) icons also for Linux (support#1570)
  • Unsaved appointment draft not shown after reload (support-1547)
  • Unsubscribe feature displayed in "Whats New" dialog even when diasbled (support#1556)

8.51.0 - 2026-07-03

Added

  • As a user I can choose the address book when creating a contact 98f3ec277
    • The contact create dialog now has a "Save in" address book picker (private, public and shared books you can write to), so new contacts no longer always land in the default address book
  • As a user I can schedule sending at more times of day 0daba097e
    • Scheduled send now offers more quick options: afternoon (1 PM) and evening (6 PM), in addition to morning and Monday morning, listed in chronological order
    • Predefined options now send within a short time window instead of one sharp time, so messages are spread out; this can be configured or disabled (see configuration documentation)
    • Added a note clarifying that scheduled messages are queued and may be sent with a short delay, so recipients may not receive them at the exact chosen time
  • As a user I can see tasks in the calendar 861dca160
    • A new "Tasks" calendar shows your tasks that have a due date next to your appointments Turn it on under Settings > Calendar, then show or hide it like any other calendar
  • As a user I can set new appointments to private by default a16c596f2
    • Mark new appointments as "Private" by default
    • Setting can be found under Settings > Calendar > Advanced Settings
    • Applies only to your own (private) calendars
  • As a user I can vertically resize the all-day section in day and week views 661ae6ee7
    • A resize bar below the all-day area lets you drag it taller or shorter when you have many all-day appointments. Desktop only; the height is not persisted.
  • As a user I see BIMI logos by local-part selector (LPS)
    • BIMI now supports local-part selectors (LPS): a domain can show a different brand logo per sender local-part, e.g. support@example.org
    • Operators can preconfigure a logo for a specific local-part and allow individual addresses on otherwise blocked provider domains
  • As a user I would like to see the creator of shared or delegated tasks (AS-236)
    • Task details now show who created a task when it was created by someone else, for example in shared task lists or when a task was delegated to you
    • The creator's name also appears on task cards in the side panel
    • Select the creator's name to open their contact details
  • Categories for shared accounts (PBSR-1476)
  • Central management of designs for Signature Designer 7387348ce
    • Template rendering switched to Mustache
    • Ops can supply additional .html templates and a designs.yaml policy (visibility, ordering, custom fields, defaults, labels, per-template metadata) via the mail-assets ConfigMap
    • ConfigMap mounted via the mailAssets.configMapName helm value at /etc/mail-assets
    • See features/signature-designer for deployment and configuration details
  • Central management of email signatures and templates (AS-76)
    • Admins can configure read-only predefined email signatures and templates via signatures.yaml and templates.yaml in the mail-assets ConfigMap (mounted at /etc/mail-assets)
    • Predefined signature and templates appear above user signature/templates in settings and the compose dropdown with a Predefined badge; cannot be edited or deleted
    • Placeholders ({{ fullName }}, etc.) are rendered at insert time using the user's contact data
    • Requires feature flags:
      • io.ox/core//features/managedTemplates: true
      • io.ox/core//features/managedSignatures: true
    • See features/signatures for configuration details
  • Feature toggle for unsubscribe feature (unsubscribeFromMailingList)
  • Introduce Tempo, a native Temporal wrapper for date and time a05e543b3
    • Tempo is a thin wrapper around JavaScript's native Temporal API (with a polyfill fallback for browsers that haven't shipped it yet). It gives the app one date/time layer with consistent formatting, locale/week semantics, and strict input validation — replacing the parallel luxon and moment.js stacks we've been carrying.
    • The ultimate (later) goal is native Temporal everywhere with luxon and moment.js removed. This commit reaches that state for luxon in src/ (only src/io.ox/core/locale.js keeps a compatibility import per the Milestone 5 transition decision). moment.js removal continues incrementally after merge: ~115 src/ files still import moment via @/moment and will burn down through Milestone 7 batches, gated by the new lint:moment-imports guardrail.
    • Developer entry point: src/io.ox/core/tempo/README.md — includes a moment/luxon → tempo cheatsheet, day-of-week conventions table, and the "When in doubt, convert to date-time" callout.
  • Port of mail d&d helper app is configurable (PBSR-1746)
  • User can send automatic email replies for every received email 07da25032

Changed

  • Appointment comments are now indicated by a chat icon instead of quotes (support#1269)
  • Detect and block external mail content client-side 2994ae75f
    • Email HTML was already sanitized in the browser; detection and blocking of external images (and other external resources such as backgrounds and fonts) now happens on the client as well.
  • Increase default height of folder picker (support#1272)
    • the folder picker was pretty small even on large screens
    • default height is now 60% of viewport height
    • maximum height is 480px, minimum height is 80px
  • Load luxon on demand via @/luxon, out of the boot bundle ed39b44c3
  • Load moment on demand instead of in the boot bundle 0bd6d63a0
  • Only preload dependencies of plugins that actually load at boot 5078f0e0d

Deprecated

  • Pin @/io.ox/core/moment removal to 8.57 dddac4bfa

Fixed

  • "Use browser default" setting doesn't seem to work for fonts (support#1493)
    • Replaced the confusing "Use browser default" and "System" compose font options with a single "Sans Serif" default; the font list is now alphabetical
    • Compose font sizes now use pixels instead of points, shown as the same px list in the settings dropdown and the editor toolbar
    • Added a "Reset to defaults" link to the compose font settings
    • Existing font and size settings are migrated automatically
  • "X" in Install OX App Suite dialog is badly visible in dark theme (support#1500)
  • Adding attachments from HiDrive to a task or contact doesn’t work (support#1525)
    • Attaching a file from a connected storage account (e.g. HiDrive) to a task or contact failed
    • Such attachments now save correctly
  • After enabling a shared account in the settings, icons and unread state are set correctly e7624f89f
  • BIMI logos in email list not automatically loaded (support#1498)
  • Cannot open quoted part of mail in mail viewer (support#1536)
    • In Safari, the quoted part of an email could not be expanded
    • Fixed the quoted-text toggle (and other in-message interactions) in Safari
  • Drive shows empty folder instead of error when listing fails c6ac00065
  • End-users might miss they applied a file filter in Drive (support#1441)
  • Inline images not shown in plain text emails (support#1496)
  • Marking an email as read via the blue dot next to the checkbox no longer works (support#1430)
    • This only affected the combination of the vertical list view and visible checkboxes.
    • The checkbox's click area overlapped the blue dot, preventing it from being clicked.
  • Pasting formatted text adds extra blank lines between lines (support#1261)
  • Redirect on LGI-0016 during manifest load (support#1478)
