Identified - This OX Cloud platform update includes the following main features: \- Categories from a searchable dropdown: Type to filter the list, or type a new name to create a category and apply it in one step. The same picker assigns categories to mails, appointments, contacts and tasks, and filters searches by category. \- Sortable mail search results: Search results can now be sorted and ordered like a normal folder, by sender, subject or size rather than only by date. Cancelling the search restores the folder's own sort order. \- Settings and notifications as side panels: The settings menu and notifications now open in a side panel instead of a floating popover, with keyboard focus moving into the panel as it opens and returning to the button that opened it on close. Calendar reminders and invitations offer a “Show in calendar” link that highlights the appointment in the current view. \- This release introduces support for Brand Indicators for Message Identification (BIMI). BIMI lets mailbox providers display a verified company logo next to incoming messages. In the OX App Suite UI, the BIMI logo is resolved and rendered locally so we can offer a preview in the compose dialogue and enrich list views. Fixes to the OX Cloud platform in this release include: \- <https://documentation.open-xchange.com/appsuite/releases/8.52/> Expected Impact: \- No user impact is expected.

Identified - This OX Cloud platform update includes the following main features: \- Since our planned sunsetting of our OX Sync App at the end of 2025, Android users have had to rely on third-party apps to synchronize contacts and calendars to their Android devices over CalDAV and CardDAV.

Starting with OX App Suite v8.48, our "Connect Your Device Wizard" provides an easy way to configure bitfire's DAVx⁵ Select app from within OX App Suite. Users will benefit from a guided onboarding process, making it easier than ever to configure synchronization in just a few steps. More information can be found in our latest OX Blog post here: <https://blog.open-xchange.com/introducing-davx-select-a-seamless-new-android-sync-experience-for-ox-app-suite> \- Renamed Vacation notice to Automatic Replies to better cover professional and personal use cases. \- Additionally, this OX App Suite release contains bug fixes and several improvements.
