A new version of the SDK is out, m5-rc15. It is another update in the process of transitioning from M3 to M5 version and now includes all the changes mentioned in the documentation when m5-rc14 was released. The update doesn't introduce any new API and does not require you to update the Eclipse ADT plugin.
The primary reason of this release is to fix a vulnerability in the handling of images. This security issue was reported by Alfredo Ortega from Core Security Technologies. It was reported that a vulnerability in the handling of images allowed complete control of the phone. The vulnerability had been identified to cause heap and integer overflow while handling GIF, PNG, BMP images.
