Google added version history to uploaded files in the documents list as well as drop downs in horizontal navigation and a new sharing experience to Google Sites.
- In addition, to the ability to "Upload any file" to Google Docs. Now you when you select "Add or manage versions" option on any file, you can upload new versions of a file, download previous versions, and delete older versions. Previously, you would have to upload new version as a new file with a new URL, re-share it, and put in the correct folders again.
- Drop down menu are now available in More actions > Manage site > Site layout.
- Sharing features in Docs, now extended to Google Sites. As with Docs, Sites now be set to one of three visibility options: private, anyone with the link, or public on the web. The new visibility option is always available at a glance at the top of each site.
With this update, new "Anyone with the link" setting makes your site available to anyone that knows unique URL, but blocks search engines from indexing the site. And for those times that someone sends you a link to a site but you don't have access, you can now request access to that site from the access denied page.
