At this moment, Ubuntu 14.04 only offers version 53 of Chromium (released at 2016-11-16), while Chrome version 56 was just released. More recent versions of Ubuntu, e.g. 16.04, are already offering Chromium version 55 (and I guess 56 will follow soon). Looking at the upstream project, chromium-browser, I see that they don't offer a newer version than 53 for Ubuntu 14.04 either.
Is there a reason why a more recent version is not available? Has chromium-browser stopped supporting Ubuntu 14.04?
While the other question is interesting, it is too wide and it does not seem to apply strictly to browsers. Both Chromium and Firefox versions are actually too new to match with the "freeze" explanation that is given as an answer of the other question.
