Android 4.4.3 KitKat update will be based on just bug-fixes, change-log leaked

Couple of days ago we reported that Google is working on a fix for the Nexus 5 camera bug that overuses the CPU of the device and drains the battery at a pretty fast pace. The fix will be rolled out via the next Android update which is 4.4.3. Now, good folks at Android Police are reporting that the update is going to be based on just bug-fixes.

"According to a source familiar with the situation, Android 4.4.3 is, unsurprisingly, going to be a pure bug-fixer release. We shouldn't be seeing new features or UI changes - Google is saving those for a more major release (let's not speculate on 4.5, 5.0, etc. - it's way too early for that)," reported Android Police.

AP has also provided a change-log for the Android 4.4.3 update, along with a screenshot of 4.4.3 running on Nexus 5, with some parts redacted. Note that the features, listed below, are from a test build, so expect to see more changes until the final version gets rolled out.

In related to the news, Myce is reporting that the Android 4.4.3 update with a build number KTU83, codenamed "Hammerhead" has been spotted running on Nexus 5. Also, the upcoming update with build number KTU79, was spotted running on Nexus 7 (2013).

There is a way to decode these build numbers using Google's build number naming convention. According to that convention, the first letter of the build is codename of the release family (example K for KitKat). The second letter allows Google to indentify the exact code branch (R for Release, T for Testing). The next letter counts quarters with A being Q1 2009 and F is Q2 2010, and two digits indicate date code.

Based on the convention, the KTU83 Android 4.4.3 build for Nexus 5 was created on the 83rd day of Q1 2014, which is 24th March. And the KTU79 build for Nexus 7 (2013) was created on the 79th day of Q1 2014, which is 20th March.

There is still no word on when Google will release the 4.4.3 update. But given the fact to a series of leaks surrounding 4.4.3, the release is expected to get rolled out anytime soon.
