The Opera browser was begun by Telenor, the leading Norwegian telecom company, in early 1994. In 1995, Opera was split off into a separate company, Opera Software SA, which remained in Norwegian hands until mid-2016, when the entire Opera browser business was purchased by a Chinese consortium for $600 million, leaving the parent company with Opera Apps & Games and Opera TV.
Opera 1.0 was an in-house project to demonstrate that Telenor’s programmers were capable of creating a compliant browser. The project began in April 1994 with version 1.0 completed in April 1995. Opera developed its own engine to render web pages.
Opera 2.0 was finalized one year later, in April 1996, and the software was released as shareware, but it wasn’t until version 2.1 that Opera was officially released. This version introduced full page scaling, allowing the user to zoom from 20% to 1000%. It was the first version available for Macs.

It includes a variety of programs to accomplish common Internet tasks such as web browsing, IRC, email.
Opera 4.0 was the first to require Windows 95 or newer when it was released in June 2000. It gained tabbed browsing and had support for both XML and Dynamic HTML. With version 4.0, Opera began using a cross-platform core.
Opera 5, released at the end of 2000, was ad-supported instead of being shareware with a free trial period. Mac requirements are System 7.5.3 through 9.2.x (there is no native Mac OS X support, but it will run in Classic Mode with OS X 10.4.11 and earlier). The installer notes that Unicode and Full Screen View are not supported. Version 5.1 added mouse gestures in April 2001.
With version 6 in November 2001, Opera gained Unicode capabilities as well as PNG alpha-channel transparency. Mac requirements include a PowerPC Mac and Mac OS 8.6 through OS X 10.2.2 Jaguar – the first Opera release for Mac OS X. Version 6.1 was the first Opera version available for FreeBSD.
With Opera 7.0, the browser moved to the Presto rendering engine in January 2003. Opera 7.0 was the first version to require Mac OS X, dropping support for the Classic Mac OS. Version 7.3 introduced voice capabilities. Version 7.5 added support for RSS news readers.
Opera 8.0 (April 2005) added Scalable Vector Graphics (SVG) support, and version 8.5 dropped ads as Opera became a truly free browser.
Opera 9 (June 2006) gained widgets and was the first to pass the Acid2 test, 9.1 added fraud protection, and 9.2 got Speed Dial, a launch page with thumbnails.
With version 11.0 (December 2010), Opera required an Intel-based Mac, and Opera 12.0 (June 2012) no longer supports OS X 10.4 Tiger.
From there, Opera skipped 13 and 14, going right to version 15 in July 2013, moving from Opera’s Presto layout engine to WebKit, which Apple uses as Safari’s layout engine and Google uses for its Chrome browser, and becoming part of the Chromium project.
Opera moved to an accelerated release schedule, as Chrome and Firefox had already done, and also released versions 16 through 19 in 2013. Opera 20-26 came out in 2014, all based on Chromium. Opera had eight releases in 2015, versions 27 through 34, and in 2016, it released Opera 35 through 42. 2017 releases range from 43 to 49.

User agent string/ID
The user agent string for Chromium-based versions of Opera resembles the Chrome string with an additional browser signature:
OPR/[version major].[version minor].[build].[patch] (edition)
This signifies the name of the browser (OPR) followed by a series of numbers denoting the build. Winreducer serial key.
Opera 25 For Mac High Sierra
An edition may be included in the string, if the build is from the developer or beta pre-release streams, or if the build has been custom-made for an Opera partner. For example, a developer channel release of Opera’s partner build with Yandex may have a signature that looks like:
OPR/25.0.1614.18 (Edition developer-Yx)
The full user agent string looks similar to this:
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.87 Safari/537.36 OPR/37.0.2178.31 (Edition beta)
