  • RLZ tracking when Chrome is downloaded as part of marketing promotions and distribution partnerships. This transmits information in encoded form to Google, e.g. when and from where Chrome has been downloaded. In June 2010, Google confirmed that the RLZ tracking token is not present in versions of Chrome downloaded from the Google website directly or in any version of Chromium. The RLZ source code was also made open source at the same time so that developers can confirm what it is and how it works.

History

Because Chromium is the open source project that results in releases of Google Chrome, the history of the two is intertwined. Chromium is a project, making all releases developmental, with Chrome being the official release.

2008

Google Chrome was first introduced in September 2008 and along with its release the Chromium source code was also made available allowing builds to be constructed from it. The initial code release included builds for Windows and Mac OS X, as well as Linux, although the latter was at a very early stage of development and lacked complete functionality. Chromium 1.0 was released in December 2008 and with it Chrome was removed from beta status for Windows only.

Upon its first release in September 2008 Chromium was criticised for storing saved passwords in a manner so that any casual user of a computer can easily read them from the GUI. Users have filed many bug reports and feature requests asking for a master password option to access stored passwords, but Chromium developers have consistently insisted that this provides no real security against knowledgeable hackers. Users have argued that it would protect against co-workers or family members borrowing a computer and seeing the stored passwords in clear text. In December 2009 Chromium developer P. Kasting stated: "A master password was issue 1397. That issue is closed. We will not implement a master password. Not now, not ever. Arguing for it won't make it happen. "A bunch of people would like it" won't make it happen. Our design decisions are not democratic. You cannot always have what you want."

2009

In January 2009 the first development versions of Chromium 2.0 were made available, featuring a bookmark manager and support for non-standard CSS features, including gradients, reflections and masks.

In May 2009 the first alpha Linux version of Chromium was made available. In reviewing that alpha version Ryan Paul said that it was "still missing features and [has] lots of rendering bugs, but it is clearly moving in the right direction." The first developer releases for Chrome on the Linux and Mac OS X platforms were made available in June 2009, although they were in a very early stage and lacked Adobe Flash

Chromium 3.0 was released on 28 May 2009 as version 3.0.182.2. Chrome 3.0 followed in September 2009 and introduced a much faster JavaScript engine, a system for user-selectable themes, improvements to the Omnibox and a redesigned new tab display page.

Chromium 4.0.212.0 was the first Chromium 4.0 version and appeared on 22 September 2009 with Chrome 4.0 publicly released in December 2009. Both brought support for extensions, plus synchronization of bookmarks along with Chrome beta versions for Mac OS X and Linux. The all-platform market penetration of Chrome/Chromium 4.0 combined was at 6.73% by the end of April 2010.

2010

Chromium 5.0 was released on 26 January 2010 with 5.0.306.0 as the initial version. Google Chrome 5.0 followed on 25 May 2010 and provided stable (non-beta) releases for all platforms. At that time the web magazine, OMG! Ubuntu!, reported that Chrome/Chromium usage was at 36.53% for Linux browsers, compared to 55.52% for Firefox and 2.82% for Opera.
Chromium 6.0 was introduced in May 2010 with the first release version 6.0.397.0. In July 2010 Chromium 6 daily builds introduced new features focusing on user interface minimalism, including a unified single page and tools menu, no home button by default (although user configurable), no "go button", a combined "reload/stop" button, bookmark bar deactivated by default, an integral PDF

, a smarter URL bar. Chrome 6 was released in both a stable and beta version on 2 September 2010 as version 6.0.472.53. The switch to 6.0 brought security fixes, a slightly updated user interface, improvements to form autofilling, synchronizing of both extensions and autofill data, along with increased speed and stability.

Chromium 7.0 was released on 17 August 2010, with 7.0.497.0 as the first version made available. This version boosted HTML5 performance to double the speed of Chromium 6. It also added hardware acceleration, which speeds up the browser in complex graphics situations by a factor of 225 times, integration of instant search, UI Tabs which move all the remaining user interface windows into the browser tabs, including the "options" menu, and 3% faster JavaScript performance.

7 October 2010 marked the release of Chromium 8.0, seven and a half weeks after that of Chromium 7. The initial release in this series was version 8.0.549.0. The development of Chromium 8.0 focused on improved integration into the Google Chrome OS

 features. These include background web applications, host remoting (allowing users centrally to control features and settings on other computers), and cloud printing. On 12 January 2011 versions of Chrome and Chromium prior to version 8.0.552.237 were identified by US-CERT as "contain[ing] multiple memory corruption vulnerabilities. These vulnerabilities include a stack corruption vulnerability in the PDF renderer component, two memory corruption vulnerabilities in the Vorbis decoder, and a video frame size error resulting in a bad memory access...By convincing a user to view a specially crafted HTML document, PDF file, or video file, an attacker can cause the application to crash or possibly execute arbitrary code." This vulnerability was publicized after Chrome version 8.0.552.237 was released fixing these problems, to alert users to upgrade versions as soon as possible.

Chromium 9.0 was released on 23 October 2010, just 16 days after Chromium 8.0, with 9.0.562.0 as the initial version. The new version introduced an infobar refresh feature with the aim of preventing website spoofing attack

s. Reviewer Wolfgang Gruener noted that the first builds of Chrome 9 have now doubled in size between Chrome 3 and Chrome 9 to a compressed download of 28.2 MB, calling it "notably more bloated". Gruener also criticized the seemingly arbitrary numbering breaks between major versions, saying, "even by more progressive standards, the version numbering may be a bit excessive. By the end of this year, Google will have gone through seven or eight different browser versions. Some may doubt the benefit of that strategy." Chromium 9 introduced two new test features in November 2010 intended to load web pages more quickly, "pre-rendering" and "false start", plus sandboxing

Chromium 10.0 was released on 3 December 2010, with 10.0.601.0 as the initial version. It introduced 18 new features, including "Instant Type" searching as well as "GPU accelerated compositing". Development of "Webpage pre-rendering" was reduced to an inactive while selectable "snap start" was introduced.

2011

Chromium 11.0 was released on 28 January 2011, with 11.0.652.0 as the initial version. Development work in this version centered on cleaning up the settings menu, including the Sync menu and eliminating all checkboxes. Reviewer Wolfgang Gruener said "The Settings menu isn’t quite as messy anymore and looks much more like what you would expect from a professionally designed software." Language and spell checking support was expanded to 100 languages. Chromium 11 used WebKit 534.18 and V8 3.1.1 which resulted in improved speed in JavaScript and other benchmark tests. In early testing Chromium 11 was faster than Firefox 4 in V8 and Kraken benchmarks, but was 12% slower than Internet Explorer 9

In February 2011, Google’s Jeff Chang announced to Chromium developers that there would be further large-scale interface changes. These may include eliminating the "Omnibox" URL bar and combining the current two line layout which has tabs on one line and and navigation buttons, menu and URL bar on a second line into one single line, thus freeing up more screen space for content. Chang indicated that this would result in URLs not always being visible to the user, that navigation controls and menus may lose their context and that the resulting single line could be quite crowded. Other proposed changes include being able to log into multiple accounts in different windows and improved URL suggestions from the user's history. By the middle of 2011, after some experimentation, the developers decided that eliminating the URL bar was too risky and shelved the idea.
Chromium 12.0 was released on 11 March 2011, with 12.0.700.0 as the first version. Initial changes in the first versions of Chromium 12 included about:flags updates of test features, incorporating an fps counter for hardware acceleration benchmarks, a P2P API interface that may indicate future platform data exchange features, an enhanced URL bar and small changes to the tabs. Chromium 12 incorporated WebKit 534.24 and V8 javascript engine version 3.2.1.1. It is anticipated that a URL bar web app launcher will be added during the development cycle. Chromium 12 also introduced a new simplified 2D logo that replaced the 3D style logo used from the project since its inception. Early in the Chromium 12 cycle the history quick provider was introduced. This feature automatically searches the browser history for websites visited in the past 72 hours looking for matching page titles and URLs. It also searches through URLs that have been typed at least twice as well as URLs that have been visited at least four times ever.

In March 2011 Google announced directions for the project for the year, including a plan for seven new major versions, planning to end the year with Chrome 17 out. Development priorities will focus on reducing the browser's size, integrating web applications and plug-ins, cloud capabilities and touch interface. The size is a concern to developers, who have noted that Chrome 1 was 9.0 MB in Windows download size, compared to Chrome 10 for Windows at 26.2 MB, as a result they have created a "bloat taskforce". Larger download sizes are a problem for a number of reasons, as Chrome Developer Ian Fette explained: "1. We do distribution deals with Chrome, where we bundle Chrome with other products. These get difficult when our binary grows. 2. We see increased download failures / install dropoffs as the binary grows, especially in countries with poor bandwidth like India. India also happens to be a very good market for Chrome (we have good market share there and growing), so that's also very problematic."

With the release of Chromium 12.0.742.0 on 19 April 2011 the interface incorporated some new changes, the most significant since Chromium 6 was released. A multi-profile button was introduced allowing users to log into multiple Google and other accounts in the same browser instance. The new tab page was also redesigned and separated into four horizontally-scrollable screens, providing access to most visited pages, Google apps, plus two identified pages. The page reload button was also redesigned along with minor changes to the URL bar. The first stable version of Chrome and Chromium 12 released was 12.0.742.91 which brought malware detection and support for hardware-accelerated 3D CSS transforms.

Chromium 13.0 was released on 26 April 2011, with 13.0.748.0 as the initial version. Early versions of Chromium 13 included a menu button to enable users to switch between multiple Google profiles, multi-selection of tabs and an improved omnibox engine. This version also included several minor GUI changes, including a slightly lightened menu bar. By early May 2011 the results of Google's attempts to reduce the file size of Chromium were already being noted. Much of the early work in this area concentrated on shrinking the size of WebKit

Later builds of Chromium and Chrome in mid-May 2011 introduced the optional "compact navigation view", aimed at mobile device users. This view combined the tab and URL/menu bars into one bar, by making the URL bar hide when not in use, thus saving 30 pixel

Chromium 14.0 was released on 2 June 2011, with 14.0.783.0 as the initial version. This initial version included about:flags testing support for preload instant search, permitting the user to preload the default search engine used in instant search and GPU-acceleration on all pages. Default changes includes 2D-accelerated canvas and the task manager incorporated a frames-per-second counter. There was also support for the Page Visibility API. By the time development of Chromium 14 had been completed and Chrome 14 stable released this version also incorporated Mac OS X Lion scrollbar compatibility and "presentation mode". It also had support for the new Web Audio API and Google Native Client

Chromium 15.0 was released on 28 July 2011, with 15.0.837.0 as the initial version. Work in this version included integrating the profiles and synchronization features, including moving synchronization into the main menu and introducing a profile manager. Synchronization data will be encrypted by default. Chromium 15 also expands webpage pre-rendering. Dan Bailey of Conceivably Tech stated about this version and the development of it, "it is obvious that Google is plugging along and is fine-tuning its browser...Chrome isn’t surrendering its perception of the most advanced browser today anytime soon." As development wound up in early September 2011 Chromium 15 also gained a "self-crashing" feature that crashes the browser if a close command is not completed in 25 seconds, smooth scrolling when using the space bar, automatic pre- and auto-logins to Google's own web pages, task bar logos to show different profiles, greatly enhanced synchronization customization, including optional search engine synchronization and improvements to the prerendering process.

Chromium 16.0 was released on 10 September 2011 at build 100523, with 16.0.877.0 as the initial version. Early in the development of version 16 an experimental Offscreen Tabs Module was incorporated which allows simultaneous user interaction with multiple web pages. This version for Mac OS-X included a move to Google's Skia 2D graphics library in place of Apple’s core graphics as previously used. This aligned Chromium for Mac with the Windows and Linux versions.

Chromium 17.0 was released on 19 October 2011, with the initial release version 17.0.913.0. This version introduced http pipelining as a test feature to increase web page load speed, starting with build 106364.
