Version history for uploaded files in Google Docs

Using “Upload any file”, users already have the ability to upload, store, and share any file up to 1 GB in size. Now you can upload new versions of the same file to your document list. Previously, each time you updated a file, you would have to upload the new version as a new file with a new URL, re-share it, and put in the correct folders again.

Editions included:
Standard, Premier, Education, Team, Partner Edition and Google Apps for Government

Languages included:
All languages supported by Google Docs

How to access what's new:
Select the “Add or manage versions” option on any file, you can then upload new versions of a file, download previous versions, and delete older versions.
