Symbian Web Runtime versions and device support

Symbian Web Runtime versions

Symbian Web Runtime (WRT) was introduced in S60 3rd Edition, Feature Pack 2 devices. Symbian Web Runtime makes it possible to use the Web Browser for Symbian 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 significant features introduced for each version of the Symbian Web Runtime platform.

Table 1. Symbian Web Runtime version information
Symbian Web Runtime version	Features introduced
1.0	First release of the Symbian Web Runtime platform. Support for widgets through built-in JavaScript objects.
1.1	Support for Symbian Platform Services through Platform Services APIs. Support for home screen widgets on compatible S60 5th Edition devices, such as the Nokia 5800 XpressMusic.
7.2 (Version number jumps to match the version number of the mobile Symbian Web Browser.)	Support for home screen widgets on additional compatible S60 5th Edition devices, such as the Nokia N97. Addition of Platform Services 1.0 API method setLeftSoftkeyLabel() to the JavaScript menu object. Full support for Flash Lite 3.0. (Flash Lite 3.0 was available in Symbian WRT prior to version 7.1 but was not fully supported.) Multi-page home screen support
7.3 (Part of the Symbian Anna mobile operating system refresh release, along with Symbian Browser 7.3. Symbian WRT 7.3 is not available as an independent release.)	Addition of Platform Services 1.0 API method device.getServicePermissions() to the JavaScript device object for Symbian Anna and later releases. This method can reduce user security prompting for a widget. Also see What's new in Browser 7.3 for related Browser changes, some of which also apply to Symbian WRT 7.3, including Split-screen virtual keyboard support and JavaScript compilation change for function declarations in conditional expressions.
7.4 (Part of the Nokia Belle mobile operating system refresh release, along with Symbian Browser 7.4. Symbian WRT 7.4 is not available as an independent release.)	None, bug fixes only. Most notably, a bug is fixed so that you can use the viewport meta tag in home screen widgets. For more information on this bug, see What's new in Symbian Web Runtime 7.3. For more information on the viewport meta tag, see Viewport meta tag support.

Widget compatibility across Symbian Web Runtime versions

The Symbian Web Runtime environment is generally backward-compatible, with exceptions specified here.

Widgets created for Symbian WRT 1.0 run normally with Symbian WRT 1.1 and later versions. You should take newer technologies, such as different display sizes and the introduction of touch UI, into consideration when running Symbian WRT 1.0 widgets on newer mobile devices.

Widgets created using the Symbian WRT 1.1 or later Platform Services APIs do not work with Symbian WRT 1.0.

For more information:

For detailed information about the features supported by Symbian WRT versions 1.0 and 1.1, see Widget features.
To determine the version of Symbian WRT in a particular Symbian device, use the JavaScript widget.wrt object.
