We're all happy to see Android 4.3 finally make its appearance, especially as it brings some pretty important and positive low-level improvements like Bluetooth Low Energy and TRIM support. Unfortunately, new versions often introduce new bugs that slip by even the most diligent testers. Jelly Bean 4.2 had its fair share of issues, including an almost comically bad oversight: the total annihilation of December in the stock Contacts app. This is why each major release is often followed by a couple of bug fix OTAs in the following weeks.
Update: Looks like we were right.
ROM developers and Android tinkering enthusiasts alike have probably noticed at this point that the new iteration of the Nexus 7, unveiled two weeks ago, does not yet have factory images or driver binaries posted on the appropriate Google Developers page. A similar issue plagued the Nexus 4 in its early days, though eventually images were posted. At the time, legal issues were speculated as a possible reason for the delay, and Android build maintainer JBQ - largely responsible for the images / binaries - said only this in response: "I can't comment."
With the new Nexus 7, JBQ has not outright said that legal problems with Qualcomm are preventing the factory images (and possibly the driver binaries) from being published, but a quick look at the relevant evidence makes it pretty duh-obvious that's what's going on.
While we haven't heard much on the Android 4.3 update news front for the One or Galaxy S4 GPE other than "soon," it sounds like soon really may mean soon. HTC just released the Android 4.3-based kernel source and framework files for the One GPE on HTCdev.
The corresponding software version for the source and framework is 3.06.1700.10, while the kernel version remains unchanged at 3.4.10. You can download the kernel right here, and the framework files here.
There's no denying the usefulness of a keyboard when doing a lot of text input on Android, and there's no shortage of Bluetooth options that fit the bill perfectly. Anyone who spends a lot of time in email or a text editor likely has one of these handy little accessories laying around, but if that user also owns a Nexus device with 4.3, then they're in for a bit of a surprise the next time it's paired up: many Bluetooth keyboards no longer work post-update.
So, you want to know about everything that's new in Android 4.3. Every single change that's occurred since 4.2.2. Well, if you don't mind scrolling through a barely-human-readable, mile-long developer changelog, now you can satisfy that urge.
Al Sutton has posted a wonderfully-formatted AOSP commit changelog covering the changes from Android 4.2.2 (JDQ39) to Android 4.3_r2.1 (JSS15J). The JSS15J build is the most recent release of 4.3, and is the one currently shipping on the new Nexus 7.
Android 4.3 was officially unveiled and released two days ago to the Android Open Source Project. In a surprisingly timely fashion, Google also released both the factory images and OTAs to the Nexus 4, 7, 10, and the Galaxy Nexus.

Ever since its inception in Android 4.2, end-users have wondered why the multi-user function has been restricted to tablets. While switching between profiles desktop-style certainly makes the most sense on tablets, there's no technical reason why it couldn't be enabled for phones as well. Yesterday an official Android engineer took to Reddit to explain the reasoning behind the limitation.
"...it is not at all clear how it should work on a phone, specifically with respect to SMS and phone calls," writes Dan Morrill, Google Engineer and a regular on the popular /r/Android subreddit.
If you've already updated to Android 4.3, whether via an OTA or by flashing it manually, and rooted it, you're more than likely using Chainfire's SuperSU, which carefully works around the new restrictions Google put in place. Cody has a good write-up about why they did it and what's going on, so go read that if you're interested in the details.
Chainfire created the Android 4.3-compatible root method and the updated SuperSU back when the first leaks showed up for the Galaxy S4 but hasn't updated it for a few weeks.
Google Maps product manager Evan Rapoport revealed another Android 4.3 change on Google+ this morning - better photo spheres. Photo spheres were introduced in Android 4.2, and I truly believe they're one of the biggest things to happen to personal photography in years. They're limited to Nexus devices for the time being - and viewing outside of Maps / Google+ is still hard - but it's encouraging to see that Google is still going strong developing the feature.
