Google Finance lets you subscribe to more information about a company. There's a new RSS feed for news, a calendar with all the conferences and other important events, the option to view and export the historical prices for a stock.
A more useful new feature is a calendar with all the important events for the companies included into your portfolio. There's no feed for news in the portfolio section, though.
Google Finance will eventually add sections for all the links from "more resources", managing to mix the best information from other financial sites with its services.
