Firmware release notes 4.8.7
Appearance
Release name: "Stecknadelhorn" 4.8.7. Release date: April 8th, 2025.

For other versions, see the DSOS release notes page.
Improvements
- Added support for SharePoint news posts created after August 2024, which expose the title area differently in the Microsoft Graph API.
Fixes
- Restoring a configuration backup generated on a device with a different DSOS license (a.k.a., Feature Set) could fail, complaining that some features are not supported even if the current license on the player supports all features.
- The timezone database used to display the list of timezones and their UTC offsets in Control Center was outdated and did not match the timezone data used by the system; this only affected the display of the timezone offset in Control Center and not the offset actually used (e.g., Almaty was shown as being at UTC+6:00, although it was in fact UTC+5:00).
Applies to all DSOS players, except HMP350, HMP300, and DiVA
- Touchscreens that implement the pointer with absolute coordinates HID protocol instead of the multi-touch protocol did not work correctly on players other than HMP350, HMP300 and DiVA. This only affects older single-touch models, modern touchscreens implement the multi-touch protocol even if they are single-touch.
Applies to HMP400W, iBX410W and third-party DSOS players
- Unconfigured players sometimes failed to show the information and QR code to connect to the Wi-Fi configuration interface at boot due to a race condition.
- The Wi-Fi configuration interface did not correctly escape backslash and space characters in passwords and other data, hence Wi-Fi networks using those characters in their configuration did not work.
Applies to iBX410/W and third-party DSOS players based on Elkhart Lake or Jasper Lake CPU platforms
- Improved system stability by optimizing GPU and CPU power states.
Applies to iBX440
- The video output streaming configuration could, in some conditions, list resolutions higher than 4K, although the hardware does not support it.
Security
- Fixed two cross-site scripting vulnerabilities (severity level: low) in Control Center.
- The Recovery Console is updated to version 2.22.0.
