Thread:Project:Support desk/General advice needed: How to handle changes in UI?

MediaWiki 1.23.6, PHP 5.4.33 (cgi-fcgi), MySQL 5.5.36-cll-lve

My wiki includes some wiki-specific help pages. Under "how to create a page", it says "type the name of the new page into the search box and press the 'Go' button".

But at some point, the 'Go' button got up and went.

So I'm wondering how administrators deal with the general problem: Improvements to the UI (or workflows, or any functionality) that make help text obsolete. Maybe we just suck it up and stay on top of things by reading change logs. But if there's some clever automatic alerting mechanism, I'd like to know about it. Pointers or advice appreciated.

(Evidence that there is no such mechanism: this help page still refers to a 'Go' button, and indeed to a search box on the left of the page.)
