Today we’re bringing autosave to Basecamp (for messages and comments), Highrise (for notes), Backpack (for messages, comments, and notes), and Writeboard (for documents and comments), as well as right here on SvN.

Autosave keeps a local copy of your work in your browser’s storage as you write, so you’re always protected against accidental refreshes, closing the wrong tab, a browser crash, or clicking a link that opens in the same window. The local copy will be kept in your browser’s local storage until you submit that message or comment.

If you accidentally close your browser or refresh the page, everything you’ve typed will be restored automatically when you return. You don’t have to do anything, it just works.

Autosave works with modern browsers: Internet Explorer 9+, Firefox 3.5+, Chrome 4.0+, and Safari 4.0+. If you’re not already using one of these versions, now’s a great time to upgrade!

We hope this gives you even more confidence in working with our products. Losing something while you’re writing it stinks – hopefully this helps cut those incidents down dramatically.
