The firmware update 5.31.108 is rolling out in a staged deployment, meaning it will become available to eligible users over a few days following the announcement.

Supported Models & Availability
The update applies to various Western Digital My Cloud models, including:
My Cloud (single bay / original)
My Cloud Mirror Gen2
My Cloud EX2 Ultra, EX2100, EX4100
My Cloud DL2100, DL4100

If your device is on that list and currently running a version of My Cloud OS 5, you should see the firmware offered automatically or via manual update.

What’s Not Explicitly Detailed
The public announcement for 5.31.108 does not list in detail which bug fixes, performance improvements, or new features are included. It is common in WD’s community posts that the update version is given without a full breakdown.
Past WD update policy and knowledge base articles suggest the following general expectations for firmware updates:
Security patches and vulnerability fixes
System stability and performance improvements
Possible enhancements to remote access, file indexing, or app compatibility
Bug fixes for known issues in prior versions
But for 5.31.108, users may need to wait for WD to publish a detailed “Release Notes” or check whether the firmware file includes a changelog.
How to Update to 5.31.108
If your device hasn’t yet received the update, here’s how to manually install it:
Download the firmware file for your specific My Cloud model via the links provided in the announcement.
Log in to the My Cloud OS 5 Dashboard (via web interface).
Go to Settings → Firmware Update → Update From File.
Select the downloaded firmware file and confirm the update.Do not power off or disconnect your device during the update process. The device will reboot automatically when done.
Recommendations & Tips
Backup your data before updating, especially if your device holds critical files.
If your model is eligible but not yet offered the update automatically, the manual install route is a fallback.
After the update, check your device dashboard and apps to verify that everything is functioning normally.
If you encounter issues (e.g. device stuck, indexing delays, app compatibility), WD Support is the best route to assistance.
