General description of the release

Main new features:

• Graphics hardware acceleration support in Symbian^3 – Mobile 3D Graphics API is accelerated by a 3D GPU, and graphics performance is optimized for mixing 2D and 3D graphics.
• Improved security user experience - The Java Runtime shows the user fewer security dialogs during runtime. For certified MIDlets, full permissions can be granted in one go.
• Improved installation user experience - The user needs to accept only a single confirmation dialog when installing a MIDlet.
• Improved MIDlet start-up experience - The Java Runtime displays an instant start-up screen and also loads faster.
