Google released new version of Google Gears!
1) Store and serve application resources locally
2) Store data locally in a fully-searchable relational database
New included features are HttpRequest and Timer.
The main reason for these modules was that developers told Google they wanted to make HTTP requests and create timers inside Gears workers, as written on Gears API Blog.
