Adobe Systems has announced the availability of version 1.5 of its AIR software for Linux operating systems.

Adobe AIR 1.5, a component of the Adobe Flash platform, enables web developers to use HTML, JavaScript, ActionScript and the free, open source Flex framework to deliver web applications outside the browser.

The company said that developers can now use Adobe AIR 1.5 technology to create software applications that are available on Linux, in addition to the Windows and Mac operating systems.

AIR 1.5 is expected to include functionality introduced in Adobe Flash Player 10, such as support for custom filters and effects, native 3D transformation and animation, and extensible rich text layout.

Offering new features and performance improvements to create more expressive AIR applications, Adobe AIR 1.5 incorporates the open source WebKit HTML engine and now accelerates application performance with SquirrelFish, the new WebKit JavaScript interpreter. Adobe AIR 1.5 is also expected to include a new, encrypted database that reportedly meets enterprise security compliance requirements while storing data more securely on customers’ computers.

David Wadhwani, general manager and vice president of the platform business unit at Adobe, said: The release of Adobe AIR 1.5 for Linux builds on our ongoing commitment to the Linux community and our legacy of creating technologies that work consistently across operating systems. Using Adobe AIR, millions of web developers can now be Linux developers, and with little effort and no additional costs, companies can now target emerging markets and a broad set of new devices where Linux is growing in popularity.
