Google Spreadsheets now uses a simplified toolbar that makes it easier to find the most commonly used formatting tools. Spreadsheet features can now be found in the new menus, which resembles the interface you're already familiar with in Google Documents and Google Presentations.
The blue 'Share' button lets you give users viewing rights, add collaborators who can edit your spreadsheets with you, or publish your spreadsheets to the web.
This release also includes speed and performance enhancements for Google Spreadsheets.
Standard, Premier, Education, Team and Partner Editions
How to access what's new:
Sign in to Google Docs, and open a new or saved spreadsheet to access the new user interface.
