A document detailing the history of the desktop version of Opera has been published. Ever wonder when a feature was first introduced or when a specific version was released? Look it up here!
If anyone spots any errors or omissions, let us know.
It should be noted that in the process of publishing this document, Opera Software has also rewritten history… 🙂
Update: An updated document has now been published. It contains more information, and also clarifies the situation with the "Elektra" name. …
The document refers to "Elektra" as a rendering engine, and also claims that Opera 5 and 6 were called "Elektra". This was not really the case. "Elektra" was the codename for the 4.0 release of Opera – the whole browser, just like "Merlin" was 9.0-9.2, "Kestrel" was 9.5-9.6, and "Peregrine" is Opera 10.
But nowadays, browser engines are supposed to have names, and people started referring to the engine in Opera 4 and then 5 and 6 (even though I'm not even sure if they had a separate "engine"). I'm not sure exactly when this started, but I have a suspicion that it was incorrectly introduced into Wikipedia, and started spreading from there. Wikipedia changed history, and the world followed 🙂
Since the popular belief now is that Elektra was just a rendering engine, and Opera 5 and 6 were built on the Elektra (Opera 4.0) foundation, Opera Software decided to go with the flow and make it easy to refer to the "engine" (i.e. rendering capabilities (thanks, Snorre :))). Each version has a version number for reference anyway.
While Opera Software has officially "rewritten" history, I hope this little piece of information is not completely lost. It might be of some remote interest to "Opera-philes" at least 🙂
