The features I (and others most likely) will enjoy the most are:

59./.hop now hides display of hop message.
60.The /echo -sa swiches can now be used at the same time.
64.The switchbar now displays scroll buttons when it is vertical and
unable to fully show all windows. The mouse wheel can be used to
scroll through the window list.
78.Added Sort dialog to Window Menu, allows you to specify the sort
order of Switchbar buttons and Windows.
86.Script errors can now be caught by adding an :error goto point to
your script. When an error occurs, the script will jump to :error
and continue running.

$error returns the error message. You can reset the error with
/reseterror. If you don't reset the error, it will propagate
backwards to any calling aliases until an :error is found and
will halt the script.

Numbers 64 78, and 86 specifically I love. So nice >:D
