+
+## Changes vs. [Unraid OS 7.3.1](/unraid-os/release-notes/7.3.1/)
+
+### Security
+
+- Security: updated bind, dnsmasq, libarchive, libidn, net-tools, nginx, openssl, shadow, sqlite, and xorg-server for security fixes. dnsmasq, nginx, openssl, net-tools, and sqlite include listed CVE coverage.
+- Fix: CVE-2026-3838.
+
+### Containers / Docker
+
+- Improvement: updated Docker to 29.5.3-1_LT.
+- Fix: VLAN Docker networks now restore gateway and default-route handling more reliably after the Docker 29 upgrade, so affected containers can regain outbound and inter-VLAN connectivity.
+
+### Storage
+
+- Improvement: updated ZFS to 2.4.3_6.18.37_Unraid-1_LT.
+- Fix: boot pool device removal works correctly again instead of failing with a GUI error in some mirrored boot pool configurations.
+- Fix: replacing a missing boot pool device no longer leaves behind a stale missing mirror member in some port-swap scenarios.
+- Fix: formatting or erasing a pool no longer crashes the GUI in a specific `sda` naming edge case.
+- Fix: corrected Btrfs RAID1 pool size and usage reporting on the dashboard for mixed-size devices.
+
+### WebGUI / System
+
+- Improvement: updated dynamix.unraid.net to 4.35.1.
+- Improvement: refreshed base system packages including bash, ca-certificates, curl, git, pkgtools, rsync, util-linux, and other core components.
+- Fix: controller views in System Devices now show the correct drives instead of sometimes including unrelated devices.
+- Fix: mDNS service discovery can recover more reliably after a temporary network loss.
+
+### Networking / Hardware
+
+- Improvement: updated cifs-utils, iproute2, libnvme, and wireless-regdb.
+- New: added libcbor, libfido2, and libmaxminddb.
+- Improvement: Intel iGPU SR-IOV controls are now hidden unless the required plugin is installed, avoiding settings that cannot be applied.
+
+### Virtualization
+
+- Improvement: updated QEMU to 10.2.3-1_SBo_LT.
+- Improvement: more accurate PCI link speed reporting for Intel Arc GPUs in System Devices, which helps when checking passthrough hardware.
+- Improvement: the VM Network Source selector is now wider and sorted more naturally, making long or numbered network names easier to scan.
+- Fix: VM context menus now stay visible when opened near the bottom of the page instead of rendering partly off-screen.
+- Fix: VM usage reporting better matches actual guest CPU activity instead of showing inflated usage during unrelated file transfers.
+- Fix: removed an outdated reboot warning from VM settings when PCI options are enabled.
+
+### Unraid API
