WebKit is also the basis for the experimental browser included with the reader, and for the default browser in, BlackBerry Browser in OS 6 and above, and mobile operating systems. WebKit's (API) provides a set of to display web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited. WebKit's HTML and JavaScript code was originally a of the and libraries from, and has now been further developed by people from KDE, and others., and some other are supported by the project.

On April 3, 2013, Google announced that it had forked WebCore, a component of WebKit, to be used in future versions of and the, under the name. WebKit is available under a license with the exception of the and components, which are available under the. As of March 7, 2013, WebKit is a trademark of Apple, registered with the U.S. Patent and Trademark Office. Contents.

Origins The code that would become WebKit began in 1998 as the KDE HTML layout engine and KDE JavaScript engine. The WebKit project was begun within Apple by Don Melton on June 25, 2001, as a of and KJS. Melton explained in an e-mail to KDE developers that and KJS allowed easier development than other available technologies by virtue of being small (fewer than 140,000 ), cleanly designed and standards-compliant.

KHTML and KJS were ported to with the help of an adapter and renamed WebCore and JavaScriptCore. JavaScriptCore was announced in an e-mail to a KDE in June 2002, alongside the first release of Apple's changes.

WebCore was announced at the in January 2003 by Apple with the release of the Safari web browser. JavaScriptCore was first included with as a private framework which Apple used in their application, while WebCore debuted with the first beta of Safari. Was the first major release of Apple's operating system to bundle WebKit, although it had already been bundled with a minor release of 10.2. According to Apple, some changes involved OS X-specific features (e.g., KWQ, OS X calls) that are absent in KDE's KHTML, which called for different development tactics. Split development The exchange of code between WebCore and KHTML became increasingly difficult as the code base diverged because both projects had different approaches in coding and code sharing. At one point KHTML developers said they were unlikely to accept Apple's changes and claimed the relationship between the two groups was a 'bitter failure'.

Apple submitted their changes in large patches containing very many changes with inadequate documentation, often to do with future additions. Thus, these patches were difficult for the developers to integrate back into KHTML.

Also, Apple had demanded that developers sign non-disclosure agreements before looking at Apple's source code and even then they were unable to access Apple's bug database. During the publicized 'divorce' period, KDE developer Kurt Pfeifle ( pipitas) posted an article claiming KHTML developers had managed to many (but not all) Safari improvements from WebCore to KHTML, and they always appreciated the improvements coming from Apple and still do so. The article also noted Apple had begun to contact KHTML developers about discussing how to improve the mutual relationship and ways of future cooperation. In fact, the KDE project was able to incorporate some of these changes to improve KHTML's rendering speed and add features, including compliance with the rendering test. Since the story of the fork appeared in news, Apple has released changes of the source code of WebKit fork in a public repository. Since the transfer of the source code into a public (CVS) repository, Apple and KHTML developers have had increasing collaboration.

Many KHTML developers have become reviewers and submitters for WebKit repository. The WebKit team had also reversed many Apple-specific changes in the original WebKit code base and implemented platform-specific abstraction layers to make committing the core rendering code to other platforms significantly easier. In July 2007, reported that the KDE team would move from KHTML to WebKit. Instead, after several years of integration, KDE Development Platform version 4.5.0 was released in August 2010 with support for both WebKit and KHTML, and development of KHTML continues. Open-sourcing On June 7, 2005, Safari developer announced on his that Apple was open-sourcing WebKit (formerly, only WebCore and JavaScriptCore were open source) and opening up access to WebKit's tree and the issue tracker. This was announced at Apple's 2005 by Apple Senior Vice President of Software Engineering. In mid-December 2005, support for (SVG) was merged into the standard build and in early January 2006 the source code was migrated from (CVS) to (SVN).

WebKit's JavaScriptCore and WebCore components are available under the GNU Lesser General Public License, while the rest of WebKit is available under a BSD-style license. Further development.

(July 2015) Beginning in early 2007, the development team began to implement (CSS) extensions, including, transitions and both 2D and 3D transforms; such extensions were released as working drafts to the (W3C) in 2009 for standardization. In November 2007, the project announced that it had added support for media features of the draft specification, allowing embedded video to be natively rendered and script-controlled in WebKit. On June 2, 2008, the WebKit project announced they rewrote JavaScriptCore as 'SquirrelFish', a. The project evolved into SquirrelFish Extreme (abbreviated SFX), announced on September 18, 2008, which JavaScript into native, eliminating the need for a bytecode interpreter and thus speeding up JavaScript execution. Initially, the only supported processor architecture for SFX was the, but at the end of January 2009, SFX was enabled for OS X on as it passes all tests on that platform. WebKit2 On April 8, 2010, a project named WebKit2 was announced to redesign WebKit. The goal is to abstract the components that provide web rendering cleanly from their surrounding interface or application shell, creating a situation where, 'web content (JavaScript, HTML, layout, etc) lives in a separate process from the application UI'.

This abstraction is intended to make reuse a more straightforward process for WebKit2 than for WebKit. WebKit2 has 'an incompatible API change from the original WebKit', which motivated its name change. WebKit2 will target Mac, Windows, and -Harmattan. Safari for OS X switched to the new API with version 5.1. Safari for iOS switched to WebKit2 since iOS 8.

According to WebKit is used as the rendering engine within and was formerly used by 's web browser on Windows, macOS, and before version 4.4 KitKat (Chrome used only WebCore, and included its own named and a multiprocess system). Other applications on macOS make use of WebKit, such as Apple's e-mail client and the 2008 version of Microsoft's, both of which make use of WebKit to render e-mail messages with HTML content. Installed base New web browsers have been built around WebKit such as the browser on mobile phones, Browser (ver 6.0+), browser, the Web browser before version 4.4 KitKat, and the browser used in from version 4.10.

KDE's web browser and also use it as the native web rendering engine. WebKit has been adopted as the rendering engine in, and (formerly named Epiphany) and, replacing their original rendering engines. GNOME's Web supported both and WebKit for some time, but the team decided that Gecko's release cycle and future development plans would make it too cumbersome to continue supporting it.

Uses WebKit as the basis of its application runtime. The latest interface update for 's employs WebKit to render its interface and built-in browser. WebKit is used to render HTML and run JavaScript in the application platform. In CS5, WebKit is used to render some parts of the user interface.

As of the first half of 2010, an analyst estimated the cumulative number of mobile handsets shipped with a WebKit-based browser at 350 million. By mid April 2015, WebKit was 50.3%. Ports The week after Hyatt announced WebKit's open-sourcing, Nokia announced that it had ported WebKit to the operating system and was developing a browser based on WebKit for mobile phones running S60.

Named, it was used on Nokia, Samsung, LG, and other Symbian S60 mobile phones. Apple has also ported WebKit to to run on the, and, where it is used to render content in the device's web browser and e-mail software. The mobile phone platform used WebKit (and later versions its ) as the basis of its web browser and the, announced January 2009, has an interface based on WebKit.

The 3 includes an experimental WebKit based browser. In June 2007, Apple announced that WebKit had been ported to as part of Safari. WebKit has also been ported to several toolkits that support multiple platforms, such as the toolkit, (EFL), and the toolkit. Included a WebKit port in the Qt 4.4 release as a module called QtWebKit (since superseded by QtWebEngine, which uses Blink instead). The on Qt also used WebKit. The Enlightenment Foundation Libraries (EFL) port – EWebKit – was developed (by and ProFusion ) focusing the embedded and mobile systems, for use as stand alone browser, widgets-gadgets, rich text viewer and composer. The Clutter port is developed by and sponsored.

There was also a project synchronized with WebKit (sponsored by Pleyo) called, which provided a meta-port to an abstract platform with the aim of making porting to embedded or lightweight systems quicker and easier. This port is used for embedded devices such as, PMP and it has been ported into,.

MorphOS version 1.7 is the first version of (OWB) supporting media tags. Forking by Google On April 3, 2013, Google announced that it would produce a fork of WebKit's WebCore component, to be named. Chrome's developers decided on the fork to allow greater freedom in implementing WebCore's features in the browser without causing conflicts upstream, and to allow simplifying its codebase by removing code for WebCore components unused by Chrome.

In relation to 's announcement earlier in the year that it would switch to WebKit by means of the codebase, it was confirmed that the would also switch to Blink. Following the announcement, WebKit developers began discussions on removing Chrome-specific code from the engine to streamline its codebase. WebKit no longer has any Chrome specific code (e.g., buildsystem, V8 JavaScript engine hooks, platform code, etc.) Components WebCore WebCore is a layout, rendering, and (DOM) for HTML and (SVG), developed by the WebKit project. Its full source code is licensed under the (LGPL). The WebKit framework wraps WebCore and JavaScriptCore, providing an Objective-C to the -based WebCore rendering engine and JavaScriptCore script engine, allowing it to be easily referenced by applications based on the; later versions also include a C platform abstraction, and various ports provide more APIs.

WebKit passes the and tests, with pixel-perfect rendering and no timing or smoothness issues on reference hardware. JavaScriptCore JavaScriptCore is a framework that provides a for WebKit implementations, and provides this type of scripting in other contexts within macOS. JavaScriptCore is originally derived from 's JavaScript engine (which is part of the KDE project) and the library. Since forking from KJS and PCRE, JavaScriptCore has been improved with many new features and greatly improved performance. On June 2, 2008, the WebKit project announced they rewrote JavaScriptCore as 'SquirrelFish', a.

The project evolved into SquirrelFish Extreme (abbreviated SFX, marketed as Nitro), announced on September 18, 2008, which JavaScript into native, eliminating the need for a bytecode interpreter and thus speeding JavaScript execution. An optimizing (JIT) compiler named FTL was announced on May 13, 2014. It uses to generate optimized machine code. 'FTL' stands for 'Fourth-Tier-LLVM', and unofficially for, alluding to its speed. As of February 15 2016, the backend of FTL JIT is replaced by 'Bare Bones Backend' (or B3 for short).

Apple has postponed production of its rumored 2018 MacBook Air model to the second half of the year, according to supply chain sources (via ). A new version of Apple's most affordable MacBook was expected to go into mass production in the second quarter, but the company has reportedly already informed supply chain partners of the deferment, without revealing its reasoning behind the decision. The sources said that Apple has informed supply chain partners that mass production of its new notebook model for 2018 will not kick off until the second half of the year, yet without explaining the rescheduling move. Some partners speculated that the postponement might be caused by problems with some key components such as processors. DigiTimes was on Apple's intention to release a new entry-level 13-inch MacBook, due in the second half of 2018, which would serve as a replacement for the MacBook Air.

Two months later, KGI Securities analyst Ming-Chi Kuo issued a research note claiming Apple has a ' set to be released at some point in 2018. Kuo didn't offer any details on what to expect in an updated MacBook Air beyond a lower price tag, but DigiTimes believes Apple could upgrade the MacBook Air with a Retina display, which has led to speculation about whether the machine will be an updated MacBook Air or a lower-cost MacBook. Bolstering these claims, Taiwanese site believes Apple is working on a more affordable version of the MacBook Air with a price point of $799 to $899, while Bloomberg Apple is working on a new MacBook that costs under $1,000, but it isn't clear whether it's in the MacBook Air family or a new sub-$1,000 machine in the MacBook line. The original plan for a second-quarter introduction pointed to an April–June timeframe, which indicated the new model could be announced at WWDC in June, but news of the deferred production makes that suggestion seem less likely, with an October release looking more probable. As a result, some MacBook Air supply chain partners who have readied their material inventories to support second-quarter production now reportedly face low capacity utilization before starting to deliver shipments in the third quarter, according to DigiTimes' sources. The current MacBook Air models haven't seen any substantial updates in. Since that time, Apple has, while the only recent upgrade to the 13-inch model has been a bump to the base processor option last June, but it's still a Broadwell chip from the 2014–15 timeframe.

This is great news for the iPad, something that everyone needs and wants and can replace the MacBook Air:) Statements like this are so misinformed and lacking in common sense. I tried exactly this very thing via an iPad Pro with keyboard cover. No can do as there are still so many times a full computer is completely necessary. Ever try webdesign on an iPad?

Serious photo editing? Audio and video conversion on the fly? Nope didn’t think so because it can’t be done yet or anytime in the foreseeable future via iPad.

Just bought a new MacBook Air to do these very things and it fills these needs perfectly, especially connected to my 27” external monitor. Love my iPad pro but in the end it’s still an over priced/glorified media consumption device imho. Apple might as well release a new Air, seeing that their product lineup is confusing at best: We have a MacBook, a Pro with only 2 ports and no touchbar, another Pro with 4 ports. And it doesn't even play nice with a Lightning Cable. But wait, you can also choose an iMac, or iMac 5k. Maybe even a Mac Pro (because it's still available online). Shiny, and so 'retro 2013'.

How old is the Mac Mini again? Oh, but 'what's a computer'? I guess I can get this keyboard. I wonder how many other Smart connector accessories are out there.

I digressed, but thanks, Apple.
