The release fixes an issue with the remote management software that caused incorrect IP addresses to be displayed in the Scanner, improves performance on networks with clients whose IP addresses change frequently, changes view order of screens in multi-observe mode, improves reliability of screen sharing sessions, enables automatic copy and paste between local and remote computers, and fixes a bug that caused clients to be incorrectly reported as Offline or Sleeping.

Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
