WebKitGTK+ in its latest development form has a new multiple web process model that allows spawning one process per web view. With GNOME's version of WebKit having this feature, the Epiphany web-browser is already making use of the new API.
was released this morning with an API to allow setting the multiple web process model and other changes like languages support within the network process and other bug-fixes. Now having this multiple web process interface, GNOME's Epiphany web-browser landed support so that it can use the WebKitGTK+ feature of having one process per web view (tab/window).
Epiphany's support for multiple web processes happened with this commit
that worked on around one thousand lines of code. This multi-process feature now puts GNOME's work on par with other open-source web browsers.
