Android build LRW73D has been spotted in the Chromium issue tracker, the build is running on a Nexus 5. The issue previously had the “Google Restricted View” label indicating it could contain information that should only be available to Google developers. Apparently it didn’t and the label was removed a day later. The same issue also confirms the existence of Project Hera.
(As always a screenshot, in case the issue is removed)
The RW73D build is almost a week old, starting with Cupcake, individual builds are identified with a short build code like LRW73D that give an indication of the build date. The first letter is the code name of the release family, e.g. L is likely Lemon Meringue Pie. The second letter is a branch code that allows Google to identify the exact code branch that the build was made from.The next letter and two digits (W50) are a date code. The letter counts quarters, with A being Q1 2009. Therefore, W is Q3 2014. The two digits count days within the quarter, so W73 is September 11th 2014. Finally, the last letter identifies individual versions related to the same date code, sequentially starting with A. So D is the fourth version of that day.
Google states on their website that the date code is not guaranteed to be the exact date at which a build was made, and it is common that minor variations added to an existing build re-use the same date code as that existing build.
As you can see in the screenshot below, the issue was also labeled with “Project-Hera”, the minus in front of it indicates the label has been removed. At the moment there aren’t any “Project Hera” issues in the Chromium Issue Tracker, but a quick search did reveal this page (screenshot below) confirming Project Hera is indeed in the works.
Hera would allow for tighter integration between search, Chrome and your mobile device, allowing for actions started out in your Chrome desktop browser to be carried over to your mobile device automatically and/or would allow UIs build with HTML5.
