datajs is a cross-browser and UI agnostic JavaScript library that enables data-centric web applications with the following features:

• OData client that enables CRUD operations including batching and metadata support using both ATOM and JSON payloads.
• Single store abstraction that provides a common API on top of HTML5 local storage technologies.
• Data cache component that allows reading data ranges from a collection and storing them locally to reduce the number of network requests.

Changes from datajs 1.0.2

The changes made since the previous release contain the following minor updates to support OData V3 services:

• The library will add the MaxDataServiceVersion header if missing from the request.
• The mime type for json payload has been changed to "application/json;odata=verbose"
• Minor fix for reading the responses to a batch request.
• Add the new EDM namespace to the metadata handler.

Despite these changes, the library still is an OData V2 client.
