My Cloud OS 5 Firmware Release Note 5.32.102

Western Digital announced the staged rollout of My Cloud OS 5 Firmware Release 5.32.102. This update is part of the ongoing OS 5 firmware series designed to improve reliability, security, and compatibility for supported My Cloud NAS and Personal Cloud devices. As with recent firmware releases, this version is being made available gradually and should appear for users over the following days. Manual download links are included in the release post for immediate installation.

Supported Devices

The 5.32.102 firmware applies to a broad range of My Cloud OS 5-compatible models, including:

• My Cloud (with 2.xx.xxx firmware)

• My Cloud Mirror Gen2

• My Cloud EX2 Ultra

• My Cloud EX2100

• My Cloud EX4100

• My Cloud DL2100

• My Cloud DL4100

• My Cloud PR2100

• My Cloud PR4100

• WD Cloud (Japan)

These are the same models supported by the prior OS 5 firmware lineup and represent WD’s current NAS lineup that supports the OS 5 feature set.

General Update Information

Staged Rollout & Availability

The firmware is being deployed in phases — meaning not all devices will receive the automatic update simultaneously. Typically, WD distributes staged firmware updates in waves to monitor compatibility and identify any widespread issues early. Users wanting the update immediately can use the provided manual download links and update via the My Cloud dashboard.

Installation Methods

Two primary methods are supported:

Automatic Update: Via the My Cloud OS 5 dashboard update notifier.

Manual Update: Download the firmware file and install it under Settings → Firmware Update → Update From File in the device dashboard. It’s important not to disconnect or power off the NAS during the process as it may corrupt the device’s firmware.

What’s New in 5.32.102

Unlike some previous WD firmware release notes that specifically list resolved CVEs and package upgrades (e.g., security fixes for GLIBC, Samba, and other libraries in 5.30.103), the official 5.32.102 announcement itself on WD Community does not publicly itemize specific changelog entries such as detailed bug fixes or individual security patches. Instead, it focuses on availability and device contact support, along with links to related user guides and solutions.

This is relatively common with newer OS 5 releases — WD sometimes publishes high-level release posts first, with more granular security advisories or technical details appearing later in product security bulletins.

However, based on WD’s ongoing firmware strategies in the OS 5 series, version updates generally include:

Security hardening, addressing known vulnerabilities and improving protection against exploitation. (Previous OS 5 updates have fixed security issues in underlying libraries or protocols.)

Stability improvements to internal services and networking components for better performance and reliability.

Bug fixes for reported issues from community feedback.

Compatibility enhancements for applications and mobile/web access systems.

Recommendations for Users

Update Promptly: Installing the latest firmware helps ensure your NAS benefits from the newest security and stability improvements.

Backup Before Updating: Always have a current backup before applying major firmware releases.

Monitor Auto-Updates: If automatic updates are enabled, devices will continue receiving staged firmware notifications without user action.

If you have specific questions about new features or fixes in 5.32.102 beyond the rollout announcement, you can also check WD’s official product security pages or the detailed release notes site (e.g., os5releasenotes.mycloud.com).
