A MediaWiki version isn't outdated the next day. See Version_lifecycle to know, how our version lifecycle works. Normally you should use always the latest stable version of MediaWiki, but there are some LTS versions, which get security fixes, too. There should be no problem (and in your own interest) to upgrade/use some of the supported versions of MediaWiki.

Weekly snapshoots of MediaWiki (called wmf-branches) are thought for Wikimedia wikis use only (like Wikipedia and sister projects). You can, if you want, use these versions, too, to get the newest changes, which are mainly untested for environments outside the wikimedia use. So you have to be very familar with MediaWiki, to know what to do, if something went wrong.
