WWDC 2017 has begun, and we've covered the announcements here.

Apple puts on a mostly-annual developers conference in California to showcase new software, software updates, and - sometimes - technologies that developers can leverage in order to make their apps more innovative and up to date. Apple calls this conference the Worldwide Developers Conference, and although it's geared toward developers, consumers are invited to watch.

There's usually a healthy dose of consumer excitement in the keynote. This year, for instance, Apple introduced a Siri-powered speaker called HomePod, a new iPad Pro with a 10.5-inch screen, watchOS 4 for Apple Watch, MacOS High Sierra for Macs, iOS 11 for iPhones and iPads, and more. In fact, here's a round-up of all the announcements.

Apple's WWDC 2017 conference takes places in San Jose, CA - rather than the usual city of San Francisco, CA - from 5 June to 9 June at the McEnery Convention Center. It means, for the first time, it is on the doorstep of Apple's new Cupertino complex.

Apple held its keynote address at 10am PST (6pm BST). It was available to watch online through the dedicated Apple website or the WWDC app on iPhone, iPad or Apple TV. It's a two-hour event. We will embed the video here when it becomes available.

Apple has announced the new version of iOS, expected for release in September. iOS 11 comes with a raft of new features. For instance, iMessages are now stored as part of iCloud, so they sync across all your devices. All your messages are stored in the cloud, but are still end-to-end encrypted for security. There are also new changes to Apple Pay, including the addition of person-to-person payments.

It works as an in-app add-on for iMessage so you can easily send payments to friends and families. Siri has a new, more natural voice and can translate from English to Chinese, French, German, Italian, etc. The Camera app improves in iOS 11, using HIEF compression for photos. They will look as good as normal JPEGs but at half the file size. Photos also now has a range of new options.

You have the ability to edit live images across the different frames, for instance. And finally, Control Center now packs all the features on one page, with sliders for volume and brightness. Then 3D touch will access individual controls, to tweak different aspects with more depth. Apple is yet to reveal the exact release date of iOS 11, but it should appear alongside the new iPhones later this "fall".

Apple has revealed some of the new features coming to Apple Watch when watchOS 4 is released later this year. The company explained that there will be new watch faces, including a Siri Watch face to see relevant content, including diary notifications, and news stories. The Music app is also improved. It has been redesigned, can automatically sync music and show cover art on the screen, and more.

Apple also showed a demo of the new dock. It will show recently used apps, so you can scroll through more easily than before. New fitness features are coming too, with playlists in Music starting when a workout begins. There are many other new features too, which we'll detail further soon. It is thought that watchOS 4 will be released in "the fall" - so a few months away yet.

Instead of announcing an all-new system with an all-new name, Apple announced MacOS High Sierra. It's a major update to Sierra, which Apple announced and rolled out last year. And Apple executive Craig Federighi wasted no time telling developers that High Sierra is "fully baked". The new macOS is about deep technology but also added some refinements, Federighi explained.

Safari is now the "world's fastest desktop browser" with High Sierra and is going after Chrome and its upcoming ad-blocking features. Safari now offers AutoPlay blocking and no longer has intelligence tracking prevention. But one of the biggest area of refinement in High Sierra is in Photos. There's now a persistent sidebar and a view that has all of your imports in chronological order.

Another big update announced is the new Apple File System. It's 64-bit, from top to bottom. Other new High Sierra features involve video and graphics; for instance, it now supports the H.256 standard for video. Apple also introduced Metal 2 and Metal VR. Remember, VR and AR apps need heavy GPU power, so we're not surprised to hear Apple announce is doubling down.

Steam VR SDK, Unity and Unreal engines are coming to the Mac as well.

Not content with updating the regular line of iMac all-in-one computers, Apple's also super-charging the iMac for professionals. The iMac Pro takes things to the next level with a huge amount of power. It comes in Space Grey and is based on the 27-inch 5K iMac design. The starting configuration equips you with an 8-core Xeon, but there will be options for 10-core or 18-core versions too.

It's not just the CPU that's ramped up, but it will be equipped with the new Radeon Vega GPUs, offering up to 16GB of vRAM. Apple said this is the most powerful Mac that it's ever made.

This iPad follows another new iPad from earlier this year. Called iPad, that device is 9.7 inches. It replaced the iPad Air 2 and starts at $329.

Apple has announced its own music system in the form of the HomePod speaker. It will be released later this year, but the company revealed a sneak peek during its keynote. The HomePod is designed to take on the Amazon Echo in smart functionality, but it also systems like Sonos in audio quality. It has a seven-beam forming tweeter array to fill a room multi-directionally, plus a 4-inch woofer.

The speaker is controlled by Apple's A8 processor. This enables many features, such as multi-channel echo cancellation and separation. However, its the smart functionality, combined with Siri voice control ("Hey Siri") and Apple Music, which, using six microphones around the circumference, streams tracks using plenty of contextual phrases. It can also, set reminders and timers and find out news, etc.

Apple's HomePod will come in white and black, and as it comes with HomeKit built into the device, it works to control smart appliances around your home even when you just interact with your iPhone from another location. It'll cost $349 and will ship in the US, UK, and Australia from December.

After several rumours suggesting it was happening, Apple has confirmed that itself and Amazon have finally settled some differences, as Amazon's Video app will make its way to Apple TV later this year. Amazon Video is the last major video app missing from Apple TV, not including All 4 and ITV Hub, and its addition would make the Apple TV a more attractive option as a set-top box.
