An unexpected treat came zooming out of Google HQ today as Android 4.4.4 OTAs and factory images have started rolling out for Nexus devices. The updates have already been posted to AOSP and Al Sutton quickly followed up with a list of the changes. Since 4.4.3 is only 2 weeks old, and I/O is merely a week away, we had a feeling this was just a security update, and it looks like that's all it is.
Most of the significant changes are centered around fixing a recently discovered vulnerability in OpenSSL. The side effect is a few tweaks to the OpenSSL, WebView, and Chromium projects. There are also a couple of small tweaks to fix some unrelated bugs in logging and security.
The lion's share of changes went to the platform CTS (Compatibility Test Suite), but that is only used to verify a device firmware is operating within Google's guidelines for Android, so this code never actually makes it to your device.
All in all, this is a pretty minor update. Still, it's making our devices a little less vulnerable, and that's rarely a bad thing. If you're interested in skimming through the changes for yourself, head over to Funky Android!
