Synology just released another update for DSM.
As usual it’s highly recommended to wait for a new XPenology boot image before you update your XPenology installation. Even though some people have claimed that the update is working with the current boot image, it’s not considered safe. I’ll post another update once a new boot image is available for download and how to upgrade.
Version:5.2-5644 What's New This update includes all bug fixes as well as security fixes in the previously released critical updates since DSM 5.2-5592. Fixed Issues Improved stability of FTP connections. Improved stability when copying large files on DS216play. Improved general stability of NTP service. Supports Data Scrubbing for iSCSI LUN (Block-Level) in Storage Manager. Improved the stability of encrypted backup in models with ARM processors. Improved general stability of Btrfs file system. Increased the connection limit for Log Receiving in Log Center. Upgraded PHP to 5.5.30 to address multiple vulnerabilities (CVE-2015-5589, CVE-2015-5590, CVE-2015-6834, CVE-2015-6835, CVE-2015-6836, CVE-2015-6837, CVE-2015-6838, and CVE-2015-3152). Fixed an issue where a DSM critical patch could not be manually uploaded when the system was in a Hybrid HA cluster. Minor bug fixes.
