Adobe Systems announced Flash Player 11 and Adobe Air 3 software Wednesday to assist developers in building more sophisticated applications with dozens of new features across smartphones and tablets as well as desktop computers.

The releases are Adobe’s biggest in two years, and will be available free of charge in early October, said Anup Murarka, Adobe’s director of product marketing. The related tools, Flash Builder and Flex, will support new features in Flash Player 11 and Adobe Air 3 by the end of the year.

The releases will enable delivery of 2D and 3D games over the Internet to various devices, Murarka said. Developers of enterprise applications will also find the 3D capabilities popular for data-centric apps. Enterprises, for example, will be able to build application dashboards to “visualize complex data sets” with 3D images, he said.

Developers will also be able to use the tools to more deeply integrate business software like Excel and Outlook in devices and to access hardware programming interfaces for functions such as Near-Field Communication being used more widely in smartphones, Murarka said.

The new versions will also help developers build more secure applications with the ability to leverage cryptographically secure random number generation, he said.

For 3D support, Abode said faster video rendering on desktops is provided through hardware acceleration. A pre-release version of those same 2D and 3D features for mobile platforms, such as Android, Apple iOS, and BlackBerry Tablet OS, is also now available, with a full production release coming “in the near future,” Adobe said in a statement.

Other features give developers the ability to package Air 3 within an application to simplify installation of apps on Android, Windows and Mac OS, much the same as Adobe has done for Apple iOS recently.
