The release candidates for Flash Player 10.1 and Adobe AIR 2.0 are now available on Adobe Labs for Windows, Mac, and Linux.

Adobe® Flash® Player 10.1 is the first runtime release of the Open Screen Project that enables uncompromised Web browsing of expressive applications, content and video across devices. With support for a broad range of mobile devices, including smartphones, netbooks, smartbooks and other Internet-connected devices, Flash Player 10.1 allows your content to reach your customers wherever they are.

A prerelease version of Flash Player 10.1 is now available for Windows, Macintosh, Linux, and Solaris operating systems.

This public prerelease is an opportunity for developers to test and provide early feedback to Adobe on new features, enhancements, and compatibility with previously authored content. Consumers can try the prerelease of Flash Player 10.1 to preview hardware acceleration of video on supported Windows PCs and x86-based netbooks. You can also help make Flash Player better by visiting all of your favorite sites, making sure they work the same or better than with the current player. We definitely want your feedback to help improve the final version, expected to ship in the first half of 2010.

Bad news for Flash developers waiting for new release of Flash CS5 to build native IPhone application is Apple banned IPhone app build with Flash CS5 or other tool like MonoTouch, Titanum,  Unity and Phone Gap.

The new change to the iPhone Developer Program License Agreement, which comes as part of the release of the new iPhone OS SDK for developers, changes all that. Originally section 3.3.1 was only a sentence long, but now it has gained several more.

Here’s the new wording of the policy in question:

“3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).”

As Daring Fireball’s John Gruber points out, the new language almost certainly means that cross-compilers are banned — you have to build iPhone apps within Apple’s pre-approved programming languages or watch your app be denied access to Apple’s app stores.
