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)

- Mozilla/[version]
