Why is Mozilla deceiving me from version to version?

Question

Mozilla

Every time after an update, Firefox wants to tell me what's new in the version I just downloaded. And carefully opens the page at, for example, www.mozilla.org/ru/firefox/9.0.1/whatsnew/ in which the version number changes.

Only here it never says what's new in the new version, but only links to some other uninteresting pages.

I even thought that the problem was the lack of a translator and replaced ru with en in the address: nothing happened. There is generally 404. And if the language index is removed altogether, then I will be redirected back to a useless Russian page.

What is it? A flaw, carelessness and laziness, a defect?
