This document provides a quick historical reference to Opera versions, release dates, release streams, rendering engines, JavaScript engine, user agent/ID strings formats, features, and improvements.
The information below describes version history for Opera browsers built using the WebKit/Chromium rendering engine, Opera versions 15.0 and above. For information about the landmarks developed in Opera’s Presto rendering engine and related Opera browsers, please see Opera’s archived version history.
Version downloads

- Opera for Windows, Mac, and Linux computers.
Opera pre-release channel builds
WARNING: These are pre-release builds. Please use them only on properly backed up computers. They contain the latest changes, but may also have severe known issues, including crashes and data loss situations. In fact, they may not work at all.
Archived Opera versions
Legacy version of Opera for Mac, Windows, and Linux can be found in the Opera archive.
User agent string/ID
The user agent string for Chromium-based versions of Opera resembles the Chrome string with an additional browser signature:
Opera For Mac
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.
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)
This string will vary depending on your operating system and the build number you are using. Broken down, these objects mean:
- Mozilla/[version]
- Signifies the browser is Mozilla compatible.
- (Operating system)
- Signifies which platform and version of operating system the browser is running on.
- AppleWebKit/[build]
- Signifies the browser is WebKit compatible.
- (Layout engine)
- Signifies the layout engine used for rendering. KHTML is open-source and developed by the KDE project.
- Chrome/[version, build, and patch]
- Signifies the browser is Chrome compatible.
- Safari/[build]
- Signifies that the browser is Safari compatible.
- OPR/[version, build, and patch]
- Signifies the Opera browser signature (See above).
- (Edition)
