Unraid OS 7.4.0 Now Available

Unraid OS 7.4.0 is out now! It adds multiple custom networks and memory limits for Docker containers, Mover progress tracking, improved file operations, a shared task tray, and new boot-device backup and power-button options. It also includes WebGUI and Unraid API security fixes, Linux kernel 6.18.60-Unraid, and base package updates that address reported CVEs.

Highlights (changes vs. 7.3.4)

Containers / Docker

• New: multiple custom networks per container template, retained through update/recreate

• New: Memory limit field in Advanced View and a live icon preview in Add/Edit forms

• Improvement: registry update checks support OCI manifests and indexes and identify the Unraid client

• Fix: Docker icon handling and orphan-image date display

Storage

• New: Mover progress and status tracking (finally!)

• Improvement: Mover preserves hard links

• Improvement: File Manager keeps exclusive shares under /mnt/user, fixing cross-share and pool moves that could lose source files

• Improvement: Enter after a valid encrypted-array passphrase starts the array

• Fix: stopped-array utilization and boot partition used/free display

WebGUI / System

• New: shared task tray for background operations, with output available from any browser tab

• New: boot-device backups, downloaded to your computer or saved to the server, with compression options and progress reporting

• New: physical power button options (Shut down, Reboot, Do nothing) under Settings → Power Settings → Power Button

• Improvement: live plugin-install progress and faster Installed Plugins page loading

• Fix: several Plugin Manager, Unraid API Status, and Power Options fixes

Security

• WebGUI pages render runtime-provided values as text rather than markup

• OpenTerminal validates request inputs; root-password setup shows only when root is unconfigured

• Anonymous diagnostics mask network addresses and user-controlled identifiers

• Notification agents verify TLS certificates for public APIs

• Unraid API: GraphQL authorization, request-size and query-complexity limits, introspection blocked when Developer Sandbox is disabled, and OIDC secret and request hardening. Clients that rely on introspection in that mode or exceed the limits may need adjusting.

Kernel and base distro

• Linux kernel 6.18.60-Unraid

• 16 packages updated, including bind, brotli, patch, and util-linux (CVE fixes), btrfs-progs 7.3, and dynamix.unraid.net 4.37.11
