Web Runtime versions

The Web Runtime (WRT) was introduced in S60 3rd Edition, Feature Pack 2 devices. WRT made it possible to use the S60 Browser engine to create small applications, called widgets. Widgets can be installed directly on the mobile device, allowing them to run without opening the browser. The following table summarizes the changes for each version of the Web Runtime (WRT) environment.

The Web Runtime environment is backward-compatible. Widgets created for WRT 1.0 run normally with WRT 1.1 and 7.1. However, you should take newer technologies, such as different display sizes and the introduction of touch UI, into consideration when running WRT 1.0 widgets on newer mobile devices. Widgets created using the WRT 1.1 or 7.1 Platform Services APIs do not work with WRT 1.0.

For detailed information about the features supported by the WRT versions, see section Widget features. For information about the Internet technology standards supported by WRT, see section Web Runtime standards.
