A new feature of the Events module is the ability to combine one or more Events module within your site into a Master Calendar.  You could use this to allow specific users to modify and display only their events within a site-wide calendar.

Event Listing

You can now link an Events module to another existing Events module in order to display its events as a list. In previous versions you could only choose to display a particular modules events in either Month or List View.

Stylesheet Use

The Events module now makes better use of Cascading StyleSheets (CSS) that you can use to change the size, color, and borders of your Events modules. CSS use is per site.

Event Navigation

The Month View now gives you the ability to more easily navigate to a specific day and drill-down to a specific week.
