A couple of days ago, AOSP was graced with a series of freshly created "l-preview" branches and a massive push of brand new code. As we know now, quite a bit of that code push wasn't truly representative of the L developer preview. (Very sneaky, Google.) Most of the truly new updates belonged to GPL-licensed projects, which Google is obligated to release in a timely fashion. The remaining projects with "l-preview" branches were filled with a recent snapshot from the Master branch.
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.
Unless you blacked out all of the news from yesterday to avoid a deluge of stories about what has been happening in Cupertino, you probably caught wind that there's a brand new update to Android. Whether you're manually installing the latest OTA or going all out with the factory images, you might be interested to know what is actually different. Thanks to Al Sutton, we've got a brand new changelog compiled from the list of code commits submitted to the Android Open Source Project (AOSP).
A brand new OTA began rolling out to the 2013 Nexus 7 LTE just two days ago, and today those changes finally appeared in AOSP. As is the tradition, Al Sutton built a list of changes and posted them to his site. Every bug fix and tweak from KOT49H (4.4.2_r1) to KVT49L (4.4.2_r2) is included. There isn't a lot to look at, but if you're interested in what's new, you can find the developer changelog here.
If you've got (a lot of) spare time on your hands this evening and a burning desire to know literally everything new in AOSP with Android 4.4 KitKat, Funky Android has done the work for you, providing a complete, comprehensive log of all commits made from 4.3_r2.1 (JSS15J) all the way up to 4.4_r1 (KRT16M).
The list is extremely lengthy, but includes handy links to Google's Android Source site where you can find more info about each commit.
