• Support importing data from smartctl even when the disk reports
  incomplete information for attributes (e.g. missing norm, worst, or
  threshold values).
• Log errors while SnapRAID scans the list of all files on a disk, so
  that the SnapRAID Daemon becomes aware of any I/O errors.
• Fixed importing of the disk serial number from the SCSI Device
  Identification VPD page (also known as VPD Page 83h).
• Various security improvements and memory leak fixes.
