The next version of Android is here… sorta.

Like clockwork, Google’s released the first beta version of its mobile operating system, Android Q, for developers. The new version of Android is available to download for all Google Pixel owners — that’s for Pixel 1, 2, and 3 — and includes a number of updates ranging from improved security to with the most notable being support for foldable devices.

One of the biggest issues facing foldable devices is how Android will adapt to the various modes when folded and unfolded. Different devices will have have different display configurations and it’s important Android can morph appropriately.

Google says Android Q comes with several optimizations to help better display apps on foldable devices and large screens. An updated Android Emulator also lets developers start testing their apps for foldable displays even without a foldable device on hand.

Portrait photos are all the rage these days, and in Android Q, Google’s taking them to another level with a feature called “dynamic depth.”

Using the depth map data collected from a camera, which include information for an isolated background and foreground, Google says apps will be able to create “specialized blurs and bokeh options.”

This is pretty neat and resembles what you can simulate with an app like Focos, which lets you change the shape of the bokeh from a circle to, say, a star, or triangle, or heart.

Android Q also makes sharing content faster. There’s a new Sharing Shortcuts feature that “let users jump directly into another app to share content.”

There’s also a host of other less visible under-the-hood updates to Android Q including a new settings panel that can be activated from within certain apps. For example, Chrome could show shortcut buttons for adjusting settings like WiFi, airplane mode, and data without you needing to go into the Settings app.

New Wifi modes have been added to benefit certain applications like gaming. Google says users will be able to toggle on a “low latency mode” which would be beneficial for “real-time-gaming” and “active voice calls.”

Android Q also comes with hardened privacy protections that’ll give users more control over when apps access their location; you can choose to only let an app access your location when it’s in use as opposed to always or never. Similarly, there are better controls to keep tabs on what files (i.e. photos, videos, audio, etc.) apps are requesting access to.

There’s a ton more of screw tightening in Android Q, including support for a AV1 video codec that aims to improve high-res video while using less bandwidth, improved Vulkan support for better game graphics, and faster ART runtimes for speedier startups in various apps. You can read about all of the updates in the first beta for Android Q on the Android Developers Blog.

There are two ways to test Android Q on your Pixel, and both are pretty easy. The first is to enroll your Pixel in the Android beta program and get the update pushed to it over the air. If you’re more experienced, you can also download the Android system image files from Google here and flash them on yourself.

Android Q is a beta and as such, it’s likely buggy. As always, update at your own risk. We advise updating a device that isn’t your primary one to prevent any potential data loss if you’re eager to try Android Q.

Now, for the most important question: What does the Q in Android Q stand for? Quiche, maybe?

A fatal Ethiopian Airlines crash this weekend has prompted President Donald Trump to ground all U.S. airplanes of a similar model.

Boeing launched an investigation on Tuesday after an Ethiopian Airlines plane crashed shortly after takeoff on Sunday. The aircraft — a Boeing 737 Max 8 — was  the same model involved in the fatal Lion Air crash in Indonesia in October.

President Trump at a White House panel made the announcement about grounding both Boeing 737  Max 8 and 9 planes in the U.S.

Any Boeing 737 Max 8 planes that were in the air during the announcement will be allowed to continue to their destination. Once the aircrafts land, they will be forbidden from flying in U.S. airspace along with other Max 8 and Max 9 aircrafts.

The U.S. is the last of any major developed country to ground the aircrafts. China, Germany, France, Canada, the U.K., and other countries grounded the planes much sooner after the Sunday crash.

A petition circulated Tuesday calling for the Boeing 737 Max 8 crafts to stop flying on Southwest and American flights. A New York Times analysis found U.S. companies Southwest and American airlines are the top carriers that use the planes in its fleets. 

The FAA released a statement shortly after President Trump’s press conference, explaining that the Boeing 737 would be forbidden from being operated  by any U.S. airlines or in any U.S. territory.

The FAA’s statement was markedly different from the one the agency released on Tuesday, when it said it  was reviewing planes and that its review so far provided “no basis to order grounding the aircraft.“

Boeing issued a statement immediately following Trump’s announcement, noting its “full confidence in the safety of the 737 Max” but that it supports the decision to temporarily ground its planes.

Beware, for this post is dark and full of spoilers for Game of Thrones Seasons 1-7.

Valar morghulis, friends. You’ve just entered Mashable’s Citadel, where we are Rewatching for the Throne, dissecting Game of Thrones season by season to prepare for the final six episodes beginning on April 14.

Here are all the best Season 4 theories, unanswered questions, unresolved plots, and forgotten tidbits you need to remember before winter comes for the endgame in Season 8.

Who can forge Valyrian steel?

Season 4 opens with Tywin melting down the Stark family Valyrian sword Ice down into two swords for House Lannister (later named Widow’s Wail and Oathkeeper).

This is a subtle reminder that Valyrian steel — the only thing that can kill White Walkers — is not only extremely rare, but also that only a few people in the world know how to re-forge it. Tywin tells Jaime he hired a blacksmith in Volantis, but in the books it’s actually Gendry’s mentor, Tobho Mott, who possesses the rare knowledge and magic needed for this skill.

Since Gendry returned to the show in Season 7, a long-standing theory is that he will use his what he learned from Mott to go a step further than just reworking. The pile of dragonglass being forged in a brief scene from the Season 8 trailer seems to all but confirm that Gendry will forge the first new Valyrian steel weapons since the Doom of Valyria.

And they’ll need it. 

Everything we learned from the White Walker transformation

One of the most important scenes from Season 4 (if not the entire series) is something we never saw in the books: the White Walkers on their home turf.

In the scene where Craster’s last son is sacrificed as a “gift to the gods,” a White Walker takes him to what we can assume is The Lands of Always Winter. It’s the part of the map no humans ever dare go, where the White Walkers hung out for thousands of years since the first Long Night. It’s also probably where they kept Craster’s transformed sons (and any other sacrificed humans) safe, raising them to maturity or until they’re more battle ready.

What this Season 4 scene with the baby at the alter gave us a glimpse into is how the White Walkers aren’t just some mindless evil. They have their own rituals, history, needs, and even culture in a sense. Inarguably, it proved their goal isn’t just the destruction of all humans because, actually, they seem to need humans (alive humans, since the zombie-like wights are different) in order to create more of their own kind. 

This culminated in a fan-favorite theory that the White Walkers’ real goal is to protect themselves from extinction, either due to the return of a threat like the dragons or to a dwindling numbers of human sacrifices to keep their population strong. 

In general, there doesn’t seem to be a lot of White Walkers left. The most we’ve ever seen together is in this Season 4 scene, where twelve stand in the background as the Night King performs the transformation. We’ve never seen any female White Walkers, leading us to believe this transformation process is their only current means of reproduction (read more in our Season 2 round up).

The fact that thirteen White Walkers are present here could have its own significance, but we’ll get to that in our upcoming Season 5 round up.

Many fans think that, despite what we’ve been lead to believe, the White Walkers won’t be defeated in war, but rather with a peace treaty. It’s also most likely what happened the first time they came during the legendary Long Night, striking some sort of agreement with the humans to stay on their side of the Wall in the Lands of Always Winter.

I mean, isn’t that more believable than the legends of The Last Hero or Azhor Ahai, which claim that a single person defeated them in combat? And isn’t it more logical that the creatures who can do ice magic built the Wall themselves, rather than the myth that it was built by humans and giants?

Some even believe that the Night’s Watch was initially created to ensure this peace was maintained between humans and the White Walkers. Which brings us to the legend of the Night’s King.

Who is Melisandre, and how much of her magic is a trick?

After the Season 6 reveal, we know that Melisandre has been using glamour this whole time to cover up the fact that she is centuries old.

But another pivotal scenes happens in Season 4, when she explains to Selyse in the bath tub that, “Most of these powders and potions are lies. Deceptions to make men think they witnessed our Lord’s power. Once they step into his light, they’ll see the lie for what it was – a trick that led them to the truth.”

Most believe that Melisandre believes in her cause, but can create illusions in the flame that lead people like Stannis to do what she believes they must do. But in general, don’t be quick to trust what any of the Red Priests show other characters in the flame.

As for who Melisandre really is, there’s no solid arguments that would be relevant to the show.

But her age, whether a couple hundred or several hundred years old, means she was alive at the height of the Targaryen dynasty. This could make her one of Dany and Jon’s most vital allies as far understanding their fire magic and dragons — potentially even helping them raise a new dragon from stone.

What did the Three-Eyed Raven mean when he said Bran would fly?

One key phrase that fans keep coming back to is the Three-Eyed Raven’s assertion to Bran that, “You will never walk again. But you will fly.”

Now, this could easily just be meant in a metaphysical sense, with Bran flying through history or even flying as a flock of ravens in one moment during Season 7. But it’s also very like George R. R. Martin to give a phrase like this several meanings.

Other theories posit that this is predicting Bran warging into a dragon, namely Viserion. Others see this is as confirmation of Bran being the Night King theory, since he’s riding Viserion too.

What will come of the Arya/Hound reunion?

It’s easy to forget, but the Hound was one of the first people on Arya’s kill list. Yet when last they were together, Arya refused his pleas for her to kill him and instead left him to die slowly on a mountain side.

He didn’t die, as we know. Actually, from the looks of the latest Season 8 trailer, he’s now at Winterfell. And so is Arya.

What will their reunion look like? Arya’s not one to show mercy to a person on her list. 

But in Season 6, she mentions the Hound twice during her training with the Faceless Men. She claims to hate him, but Jaqen accuses her of lying. Later when the Waif questions her about the Hound, Arya says she didn’t kill him because she’d taken him off her list, and didn’t really want him dead anymore.

The Hound seemed to glow with a sense of pride when Brienne told him that Arya’s become a true warrior in the Season 7 finale. So it’s clear he holds no hard feelings toward her.

Tyrion might not be a Lannister, and is actually a secret Targaryen

A running joke is that just about everyone is a secret Targaryen, from Varys to Craster. But when it comes to Tyrion, there are just way too many sly hints to ignore.

Throughout his Season 4 arc with Tywin, Tywin says every variation of “you are not my son” imaginable. There’s a lot more textual proof that Tyrion’s Season 1 assertion that, “All dwarves are bastards in their father’s eyes,” is literal. He could very well be a bastard of Dany’s father, Mad King Aerys.

Throughout the books, people talk about how King Aerys openly lusted after Joanna Lannister, Tywin’s wife. It is almost certain he had sex with her at least once. Rumor has it that before she married Tywin, Joanna was Aerys’ mistress, and eventually dismissed as the Queen’s  lady-in-waiting for that reason. Then there’s the story of how Aerys took “liberties” with Joanna during the bedding ceremony of her and Tywin’s wedding. 

All of this set the precedent, but the timing wouldn’t make sense, since Joanna was never around Aerys much after that. Until George R. R. Martin made a point in A World of Ice and Fire to state that Joanna attended a celebration in honor of Aerys reign in 272 AC. He publicly made comments on Joanna’s breasts and, later for unknown reasons, Tywin tried to resign as Hand of the King. 

A little under a year later, Tyrion was born. And some can’t help but speculate that his “deformities” were caused by incestuous Targaryen genes.

The show only added fuel to the flames in Season 6 when Tyrion had a whole scene with Daenerys’ pissed off dragons, unchaining them. We cannot stress enough how badly this should’ve gone for Tyrion. The fact that they accepted him is some of the best evidence to support that they sensed his Targaryen blood.

The biggest hitch to this theory is that fans aren’t sure why it’d even matter at this point if Tyrion were a Targaryen.

Before Season 7, the speculation is that he’d be the “third head of the dragon,” AKA he’d ride Viserion while Jon would take Rhaegal and Dany would continue to dominate with Drogon. But Viserion is gone now. And there’s not enough bonding time in the world that would make him able to be ridden by Tyrion.
