Manual talk:MediaWiki feature list/Archive

To enable or disable smart caching (?)
It is mentioned in the feature list that there is an optional smart caching. How do I enable or disable that caching? Is it enabled by default? Thank you.

I wouldn't know how one might disable this feature.

Other wikimedia project
Will there come a link system in wikimedia so we can link the other wikimediaprojects so we can see under or above the interwiki links in wikipedia for linking to wiktionary and commons and other projects pages (to promote them a bit) and share these info?

Or schould it be done wit external links under the article.
