In conjunction with Google I/O we're releasing a new version of Gears, 0.5.21.0. This version includes minor bugfixes and three new features:
- Drag & Drop support for dragging files into a web page and letting the web page act on those files
- Image thumbnailing
- Blob builder API, which allows script to build binary blobs, including valid multi-part-form-encoded blobs that contain binary file parts, which can then be uploaded using Gears.HttpRequest
Documentation on http://code.google.com/apis/gears/ will be updated soon with more details about the new features.
