Important Notes

• For the status of QTS updates and maintenance for your NAS model, visit https://www.qnap.com/en/product/eol.php
• We have fixed the vulnerabilities in the following apps to ensure your data security: Surveillance Station, QVPN Service, Qfiling, Qsync Central, QcalAgent, and IFTTT Agent. To continue using these apps, go to the App Center and update them to the latest version.
• For more information on the kernel versions for NAS models that QTS 4.4.1 supports, see https://www.qnap.com/en/release-note/kernel
• Removed the following applications from App Center due to PHP 7 updates in QTS 4.4.1: "phpEasyProject", "Dolphin", "CMS Made Simple", "Vtiger CRM", "iStat", and "PostgreSQL 9.3.13.3".
• Due to PHP 7 updates in QTS 4.4.1, PostgreSQL 9.3.13.3 can no longer work with phpPgAdmin. If you use phpPgAdmin to manage your data, ensure that you have exported the data before updating QTS. To transfer your data from PostgreSQL 9.3.13.3 to 11.4.1, you must manually export and then import the data.
• Due to compatibility issues, the following applications have been removed from the App Center in QTS 4.4.1: FileFlex, MantisBT, SugarCRM, Xeams, DokuWiki, and Azure Storage.
• Once you update QTS to 4.4.1 (or later) on the TS-1635AX, you will not be able to downgrade QTS to versions earlier than 4.4.1.
• Removed support for Plex Home Theater from HybridDesk Station.

Fixed Issues

• Storage ＆ Snapshots would display erroneous disk temperature values in S.M.A.R.T. information.
• Non-administrator users could not create subfolders in the "home" folder.
• Music Station would not automatically display album covers even when they were available.
• QTS could not run the ImageMagick PHP extension after QTS 4.4.1 and PHP 7 updates.
