There's one security update released today and that is libtiff. This package is now upgraded to the latest version which fixed the problem.
Another change happening in the latest batch of update is the change of the shell being used in the installer setup script. In the past, Bash was avoided because it's considered bloated and at that time when floppy disks are still the main media, size does matter. So the choice goes to Busybox. Right now, the size is no longer a problem, so Pat decided to go back to Bash.
Another reason to change into bash is because there has been some report about a bug in the installer setup script since last month on LQ. Pat finally decided to go back to genuine bash and that should fix the problem away.
