Appcelerator has released Titanium Mobile 1.6, an update to its cross-platform app framework for Apple iOS and Google Android.

The update adds 26 features for Android and 9 features for iOS. The Facebook API has been completely redone, keeping up-to-date with the latest Facebook API. There is beta support for the Android NDK – native code development.

Android 1.6 is now deprecated and will not be supported in future releases.

While not a big release in itself, Titanium Mobile 1.6 is require for using forthcoming Titanium+Plus modules, libraries which add support for features such as barcode reading and PayPal payments.

There is no sign yet of Aptana integration, following the acquisition of this JavaScript IDE in January.

Updating to the 1.6 SDK was delightfully easy on Windows. Just open Titanium Developer and click the prompt.
