Due to popular demand, Opera Software showed interest in programming its browser for alternative operating systems such as Apple Macintosh, QNX and BeOS. On October 10, 1997, they launched "Project Magic", an effort to measure user interest in the development of new Opera releases for other operating systems, in order to fund the development of a new version appropriately.{{cite web|url=http://www.operasoftware.com/alt_os1.html |title=Opera Software - Opera for OS/2, Mac, X11, BeOS... |author=Helmar Rudolph |archive-date=February 12, 1998 |work=operasoftware.com |url-status=dead |archive-url=https://web.archive.org/web/19980212101338/http://www.operasoftware.com/alt_os1.html }} On November 30, 1997 they closed voting for which operating system to develop with. Project Magic then became a news column for updates for alternative operating systems until version 4.{{cite web|url=http://www.operasoftware.com/alt_os.html|archive-url=https://web.archive.org/web/19980212095651/http://www.operasoftware.com/alt_os.html|title=Opera Software - Opera Winfree!

In 1998, Opera 3.5 was released, adding Cascading Style Sheets (CSS) support, TLS 1.0{{cite web|url=https://help.opera.com/en/operas-archived-history/|title=Opera's archived version history 1-12|access-date=2024-06-03}} the Elektra rendering engine, and file upload capability.{{cite web|url=http://www.blooberry.com/indexdot/history/opera.htm|title=Browser History: Opera|last=Wilson|first=Brian|access-date=2008-02-19}}

Since version 3.5, Opera has supported CSS, and Håkon Wium Lie, one of the inventors of CSS, is the CTO at Opera.[http://www.meyerweb.com/eric/articles/webrev/199906.html CSS: If not now, when?], Eric Meyer, June 1999, retrieved on October 25, 2005 Up to 6.0 Opera supported most common web standards, Netscape plugins and some other recent standards such as WAP and WML for wireless devices, but its implementation of advanced ECMAScript (of which "JavaScript" is an implementation) and the HTML Document Object Model was poor.

Version 3.6 was released on May 12, 1999.{{cite press release|url=http://www.opera.com/press/releases/1998/12/15/|title=Opera Software Releases 3.60|publisher=Opera Software|date=December 15, 1998|access-date=2008-12-10}} The 16-bit version of Opera for Windows 3.62 is the last version to support Windows 3.x.

}} Opera 7 was released, introducing the new "Presto" layout engine, with improved CSS, client-side scripting, and Document Object Model (DOM) support. Mac OS 9 support was dropped.

Version 7.0 saw Opera undergo an extensive rewrite with the faster and more powerful Presto layout engine. The new engine brought almost full support for the HTML DOM meaning that parts of, or a whole, page can be re-rendered in response to DOM and script events.

A 2004 review in The Washington Post described Opera 7.5 as being excessively complex and difficult to use. The review also criticized the free edition's use of obtrusive advertisements when other browsers such as Mozilla and Safari were offered free of charge without including advertisements.{{cite news

In August 2004, Opera 7.6 began limited alpha testing. It had more advanced standards support, and introduced voice support for Opera, as well as support for Voice XML. Opera also announced a new browser for Interactive Television, which included a fit to width option Opera 8 introduced. Fit to Width is a technology that initially utilized the power of CSS, but it is now internal Opera technology. Pages are dynamically resized by making images and/or text smaller, and even removing images with specific dimensions to make it fit on any screen width, improving the experience on smaller screens dramatically. Opera 7.6 was never officially released as a final version.

On January 12, 2005, Opera Software announced that it would offer free licenses to higher education institutions,[http://www.opera.com/pressreleases/en/2005/01/12/ Students surf safely with Opera: Opera site license free for educational institutions], January 12, 2005, retrieved on October 25, 2005 a change from the previous cost of $1,000 USD for unlimited licenses. Schools that opted for the free license included Massachusetts Institute of Technology (MIT), Harvard University, University of Oxford, Georgia Institute of Technology, and Duke University. Opera was commonly criticized for having been ad-sponsored, since this was seen as a barrier to gaining market share. In the newer versions the user was allowed a choice of generic graphical banners, or text-based targeted advertisements provided by Google based upon the page being viewed. Users could pay a license fee to remove the advertisement bar.

In 2003, MSN.com was configured to present Opera browsers with a style sheet used for old versions of Microsoft Internet Explorer.{{cite news

}} The outdated style sheet that Opera received caused Opera to move a significant amount of MSN.com's content 30 pixels to the left of where it should be, distorting the page and making it appear as though there was a bug in Opera.{{cite news

In response, the Opera Software company created a special "Bork" edition of Opera which displayed gibberish instead of MSN.com but not on any other web site. They said they did this to make a point about the necessity of a harmonious relationship between web browsers and web sites.{{cite press release

After the complaints, Microsoft changed their servers to present the latest version of Opera, version 7, with the style sheet served to the latest version of Internet Explorer, which resolved the problem. However, Microsoft continued to serve the outdated style sheet to the older Opera 6.

In November 2004, Opera Software sent an electronic message to Microsoft, complaining that Opera users were sent an incomplete JavaScript file when using Hotmail (now Outlook.com). The incomplete file prevented Opera users from emptying their "Junk E-mail" folders. The Opera Software company later sent a physical letter to Microsoft. Nevertheless, as of February 11, 2005, Microsoft had neither replied to the messages nor corrected the issue.{{cite web

Version 9.6 improved Opera Link with the new opportunity to sync custom search engines and typed history. Feed preview and an updated Opera Mail client were additional changes.

Version 10 (Peregrine) debuted in a first beta version on June 3, 2009 and scored 100/100 on the Acid3 test, but failed the smoothness criteria. There was also a preview build that scored 100/100, released on March 28, 2009. Among other features, it also came with speed optimizations, inline spell checking for forms, an auto update feature, HTML mail formatting, web fonts and SVG font support, alpha transparency support using the RGBA and HSLA color models, and an updated version of the Opera Dragonfly web debugger. Opera Turbo, a mode which uses Opera's servers as proxy servers with data compression, reducing volume of data transferred by up to 80% (depending upon content), and thus increasing speed, was introduced.

Opera 10 was officially released on September 1, 2009. Within a week of release, 10 million downloads had been recorded.

The 10.5x versions (codenamed Evenes) also came with a new JavaScript engine, Carakan, and a new graphics backend dubbed Vega (replacing the previously used Qt), that have increased its speed measurably. Then version 10.60, which Opera Software claims to be 50% faster than Opera 10.50, which also brought up new features like Geolocation, WebM support, AVG malware protection, Speed Dial improvements, etc.

Opera 10.63 is the last version to support Windows 9x and Windows NT 4.0, as later releases would require at least Windows 2000.

Opera 11 (codenamed Kjevik) was released on December 16, 2010 with new features including extensions, tab stacking, visual mouse gestures, new installer (Windows only) and safety improvements to the address field. In addition, the content blocker list now can be synchronized through Opera Link.{{cite web|url=http://www.opera.com/press/releases/2010/12/16/|title=Are you ready for Opera 11?|work=Opera Desktop Team|date=December 16, 2010|publisher=Opera Software|access-date=December 16, 2010}} It also passes the Acid3 Test as of January 22, 2011.

On April 12, 2011, Opera 11.10 (codenamed Barracuda) was released. It contains many fixes "under the hood", such as improved Turbo Mode, a plug-in installation wizard and a rewritten Speed Dial. Opera 11.10 was updated to use the new Presto 2.8 Rendering Engine.

Notes

• Windows 10 is only for IA-32 and x64, not for ARM64 and ARMv7.
• Only x86-64 builds of Opera for Mac are available at this time. ARM64 builds should soon be available as the Apple transition to ARM processors continues.
