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. In close partnership with bitfire web engineering GmbH, we now recommend users download its free-of-charge DAVx⁵ Select app from the Google Play Store, which will allow them to synchronize contacts and calendars between OX App Suite and Android devices. 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. A full list can be found here: https://documentation.open-xchange.com/appsuite/releases/8.48/changelogs/ui.html and https://documentation.open-xchange.com/appsuite/releases/8.48/changelogs/middleware.html

This OX Cloud platform update includes the following main feature:
- Users can now save or download emails via keyboard shortcuts. This is particularly useful for employees who regularly export messages to external systems, such as electronic archiving solutions.

- Additionally, this OX App Suite release brings a range of user experience improvements across mail, calendar and task components. A list of all improvements can be found here: https://documentation.open-xchange.com/appsuite/releases/8.47/changelogs/ui.html
