• Snow Leopard compatibility [feature 2845796] (Thanks again to Steve Anthony)
• Improved limits on output from syslog to STDOUT
• Simplified startup of services on Leopard and Snow Leopard
• Fixed bug in creation of user account lists in Snow Leopard where system accounts would show up
• S.M.A.R.T. status verification is now being done in the expert mode. I still want to implement this using smartmontools, but for now diskutil will do.
• Blessing of Mac OS X System folders on attached volumes is now possible. This is a primitive bless, ie, it does not create boot files, but simply blesses the chosen System folder and (optionally) sets it to be used for startup on next launch.

Leopard-compatible version (see http://sourceforge.net/projects/applejack for details)

* Compatible with Intel-based Mac OS X systems.
* Added an automated uninstaller routine, to enable easy and almost foolproof uninstallation of AppleJack.
* Added /var/root/Library/Caches to the system cache cleanup routine.
* Experimental expert mode exists, but is currently hidden until it can be tested further. (see Appendix B). The only well-tested options at this point are the memory test using the included Memtest utility, and the option to disable auto login.
* Improved the internal coding of user-input prompts. Uses a standardized interface for these functions now.
* The preference file check now uses a null byte character to separate files rather than an arbitrary "improbable" string.
