A couple of days back, a new firmware for Nexus 5 leaked online with a build version of KTU65 running on Android 4.4.3. The update was alleged to fix the camera problem and the battery drain issue.
According to the recent report from Myce, the latest Android 4.4.3 version with build number KTU83 has been sighted running on Nexus 5, which is code-named Hammerhead.
In addition, another Android 4.4.3 firmware with a build number KTU79 was spotted running on Nexus 7 (2013) model.
According to the naming convention followed by Google, the first letter of the build is the code-name of the release family (i.e. K for KitKat). The second letter denotes the branch code (i.e. R for Release). The following character denotes the quarter (U stands for Q1 2014) and the next 2 digits denote the date code (83 denotes the 83rd day in the quarter, i.e. March 24), writes XDA Developers.
With the patterns sorted out, the latest KTU83 Android 4.4.3 build for Nexus 5 was created on the March 24 2014.
With the new leaks on the possible Android firmware update for both Nexus 5 and Nexus 7 (2013), it is only a matter of time before we get the official date of the rollout of Android 4.4.3.
