Android 4.4 KitKat release date, news and rumors

Having long expected version 5.0 of Android to be given the code name Key Lime Pie, Google instead handed the 'K' release name to Android 4.4 and in a weird cross-promotional deal it called it Android KitKat.
As part of the deal Nestle is running a contest to win a Nexus 7 or Google Play credit through specially
branded Kit Kat bars.
So, apart from the fact that the chocolate bar has a space between Kit and Kat and Android 4.4 doesn't. what do we know about KitKat so far?

Android 4.4 release date

Android 4.3 recently arrived on the Nexus 7, Nexus 7 2012, Nexus 4, Nexus 10 and Samsung Galaxy Nexus but is yet to roll out to other devices. It'll also be arriving 'soon' on the HTC One and Samsung Galaxy S4 Google versions, with HTC saying it expects to push it out to developers by the end of September.
So now we can start to look forward to the Android 4.4 KitKat release date. But when? We'll take a guess at late October or early November 2013 for now - which is when we were previously expecting to see Android 5.0 break cover.
On September 20 Nestle Germany confirmed an October launch for Android KitKat on its German KitKat Facebook wall, replying to a question with a translated message which reads: "Hi Tim, Android 4.4 KIT KAT is available in October".
A release date earlier tipped to Ausdroid which turned out to be incorrect was October 14, as was October 15 which was a date supposedly overheard at Google's October Launchpad developer event.
Writing on his Google+ page on 3 October, Artem Russakovskii of Android Police said that the Android 4.4 release date is actually October 31, a date that was set some time in early September.
"Dates do change, and my information is about a month old, so if KitKat or the Nexus are delayed, Google may not hit the October 31 date," wrote Russakovskii. "I really don't see them finishing everything early, so I wouldn't bet on anything earlier than that date."
Russakovskii added that this date fits with a rumoured October 14 TA (Technical Acceptance) date for the next Nexus, which had been earlier misinterpreted by the media as the release date.
Update: Google seems to be playing a bit of a game with us now after posting a couple of teasing statues on its official Google+ KitKat page which the world has taken to be a series of cryptic clues. Are they right? We'll let you decide.

Android 4.4 features

Android 4.3 came with a few minor upgrades including better multi-user customisation, support for Bluetooth smart technology and an updated keyboard. As a minor release, Android 4.3 didn't even get its own desert-themed name, sharing the Jelly Bean moniker with Android 4.1 and 4.2.
So with a brand new code name, we can expect Android 4.4 to bring some bigger changes, but all Google is saying at this stage is: "It's our goal with Android KitKat to make an amazing Android experience available for everybody."
From this, we can assume that Google wants to get Android onto less powerful devices, something we were previously hearing about Android 5.0 when it was claimed that the new OS would be optimised to run on devices with as little as 512MB of RAM.
We also learned from Android Central back in February 2013 that Google is working with the Linux 3.8 kernel. One improvement that this kernel brings is lowered RAM usage, which fits with Google's goal of bringing Android to more devices.
The source who tipped Ausdroid with the October 14 release date also leaked some supposed details of the new OS, confirming that it would be available for "older phones", adding that it would also bring gallery visualization tweaks, new animation APIs, new notification widgets and the ability to change the Android default blue to other colors.
Leaked screenshots sent to 9to5Google, as well as other sites, show what might be a sneak peak at the Android 4.4 phone and messaging apps. The screenshots show a cleaner design and a lighter colour, plus a status bar that changes colour according to the colour scheme selected.
