Important Notes

• To prevent malware and ransomware from exploiting SMB v1 vulnerabilities, QTS now automatically sets the lowest SMB version to SMB v2 if your lowest SMB version is SMB v1 before this firmware update.
• To ensure your device security, QTS will automatically install Malware Remover after this firmware update if Malware Remover is not already installed on your device. This installation will only be performed once.
• When QTS 4.3.x is installed on NAS models running on 64-bit Intel and AMD processors, some applications may not be supported. To check if installed apps on your NAS are compatible with QTS 4.3.x, download the QTS 64-bit compatibility tool 197and install it on your current QTS build.

• Starting from QTS 4.3.4, QNAP NAS devices no longer support creating storage pools or static volumes using NVMe PCIe/M.2 SSDs. However, this limitation does not apply to the SSDs installed in built-in M.2 slots or on QM2 expansion cards.
