Going From Version To Version

What do I need to do to go from version 8.6 to 8.7? Can I transfer some of the updates to 8.7 from 8.6 to save on redownloading them all? What is the best way to update to the newest version? Thanks.

A: As long as release notes or installation hints don't recommend other, you may unpack a new version's archive (.zip) over/into an existing structure, if you let existing files be overwritten.
Of course you may use the automatic self update functionality instead.
