Important Notes

• This release mainly includes security updates for security issues in the open-source software Netatalk and OpenSSL, as well as other fixes.
• 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. (https://download.qnap.com/QPKG/CF64_0.1-1114.qpkg.zip)
• 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.
• To ensure your data security and reduce potential risks, we recommend avoiding exposing the SMB service to the Internet. Only use the SMB service on your local network. We also recommend disabling SMB v1, which is an insecure protocol known for its vulnerabilities.
